Introduction
FGF-basic is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein functions as a modifier of endothelial cell migration and proliferation, as well as an angiogenic factor. It acts as a mitogen for a variety of mesoderm- and neuroectoderm-derived cells in vitro, thus is thought to be involved in organogenesis. Three alternatively spliced variants encoding different isoforms have been described. The heparin-binding growth factors are angiogenic agents in vivo and are potent mitogens for a variety of cell types in vitro. There are differences in the tissue distribution and concentration of these 2 growth factors.

Introduction
Vascular endothelial growth factor is an important signaling protein involved in both vasculogenesis and angiogenesis. As its name implies, VEGF activity has been mostly studied on cells of the vascular endothelium, although it does have effects on a number of other cell types (e.g. stimulation monocyte/macrophage migration, neurons, cancer cells, kidney epithelial cells ).VEGF mediates increased vascular permeability, induces angiogenesis, vasculogenesis and endothelial cell growth, promotes cell migration, and inhibits apoptosis. In vitro, VEGF has been shown to stimulate endothelial cell mitogenesis and cell migration. VEGF is also a vasodilator and increases microvascular permeability and was originally referred to as vascular permeability factor.
Elevated levels of this protein is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy.

More Info

Introduction
TNFR2 belongs to the TNF-receptor superfamily. TNFR2 is receptor with high affinity for TNFSF2/TNF-alpha and approximately 5-fold lower affinity for homotrimeric TNFSF1/lymphotoxin-alpha. TNFR2 mediates the majority of the metabolic effects of TNF-alpha. In addition, knockout studies in mice propose a role for TNFR2 in protecting neurons from apoptosis by stimulating antioxidative pathways. TNFR2 expression might have a significant role in the angiogenesis, tumor cell proliferation and metastasis of Invasive micropapillary carcinoma of the breast.
There are 2 types of soluble TNF receptors: sTNFR-I and sTNFR-II, which act to neutralize the biological activities of TNF alpha and TNF beta. The levels of these soluble receptors seem to increase as a result of shedding of the extracellular domains of the membrane bound receptors. High levels of soluble TNF receptors are found in the amniotic fluid of pregnant women. TNFR2 and TNFR1 form a heterocomplex which mediates the recruitment of 2 anti-apoptotic proteins, c-IAP1 and c-IAP2, which possess E3 ubiquitin ligase activity. IAPs’ function in TNF-receptor signaling is unknown; nevertheless, c-IAP1 is believed to potentiate TNF-induced apoptosis by the ubiquitination and degradation of TNF-receptor-associated factor 2, which mediates anti-apoptotic signals. Oxidative stress promotes TNFR1 and TNFR2 self-interaction, ligand-independent and enhanced ligand-dependent TNF signaling. TNF-a, TNFR1 and TNFR2 have roles in cellular differentiation. TNFR1 and TNFR2 function in cell type-specific renal injury.

Introduction
HDGF is a member of the hepatoma-derived growth factor family. HDGF plays a role as a secreted mitogen from the human hepatoma cell line Huh-7. HDGF is a nuclear targeted vascular smooth muscle cell mitogen as well as a heparin-binding protein that is greatly expressed in tumor cells where it stimulates proliferation. HDGF takes part in organ development and lung remodeling after injury by promoting proliferation of lung epithelial cells. HDGF plays a role in the carcinogenesis of gastric epithelial cells through promotion of cell proliferation by Erk1/2 activation. HDGF is linked with tumorigenesis and the growth of cancer. HDGF is a self-regulating factor connected with the prognosis of liver cancer, non-small cell lung cancer and pancreatic cancer. HDGF has proliferative, angiogenic, and neurotrophic activity. HDGF is a distinctive nuclear targeting growth factor that is vastly expressed in HCC cells and is a prognostic factor for HCC.

Background
Endothelial cells express 3 different vascular endothelial growth factor receptors: VEGFR-1 (Flt1), VEGFR-2 (KDR/Flk1), VEGFR-3 (Flt4) which are a part of the receptor tyrosine kinases family. Those receptors express mostly in endothelial cells, but VEGFR-1 can also be found on monocytes, dendritic cells and on trophoblast cells. Flt1 contains 7 immunoglobulin-like extracellular domains, a single transmembrane region and an intracellular split tyrosine kinase domain. Flt-1, when compared to VEGFR-2 receptor has a higher affinity for VEGF but a weaker signalling activity. VEGFR-1 also mediates signals for differentiation.

Introduction
Vascular endothelial growth factor is an important signaling protein involved in both angiogenesis and vasculogenesis.VEGF activity has been mostly studied on cells of the vascular endothelium, although it does have effects on a number of other cell types (e.g. stimulation monocyte/macrophage migration, neurons, cancer cells, kidney epithelial cells ).VEGF mediates increased vascular permeability, induces angiogenesis, vasculogenesis and endothelial cell growth, promotes cell migration, and inhibits apoptosis. In vitro, VEGF has been shown to stimulate endothelial cell mitogenesis and cell migration. VEGF is also a vasodilator and increases microvascular permeability and was originally referred to as vascular permeability factor.
Elevated levels of VEGF is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in VEGF have been associated with proliferative and nonproliferative diabetic retinopathy.

Background
Neurofilament light chain (NEFL) is a critical component of the neuronal cytoskeleton, primarily found in neurons of the central and peripheral nervous systems. While extensive research has been conducted on NEFL in human and rodent models, the study of NEFL in bovine nervous tissues is an emerging area with potential for advancing our understanding of neuronal biology in larger mammals and its applications in veterinary medicine and neurobiology.
Bovine nervous tissues, such as the brain and spinal cord, are of particular interest due to their relevance in cattle health and the food industry. This research aims to provide a comprehensive exploration of NEFL in bovine nervous tissues, elucidating its functions, structural significance, and potential applications.
The primary objective of this research is to elucidate the role of NEFL in bovine nervous tissues, particularly in maintaining the structural integrity of neurons and axons. In vitro and ex vivo experiments, utilizing bovine neuronal cell cultures and tissue specimens, will be conducted to investigate how NEFL contributes to neuronal morphology, axonal transport, and neuronal resilience. Understanding these mechanisms is fundamental for deciphering the complexities of neuronal biology in bovine species.
The second objective is to assess the relevance of bovine NEFL in veterinary medicine. Studies involving bovine models will be conducted to evaluate the impact of NEFL mutations or variations on neuronal health, disease susceptibility, and neurodegenerative conditions. These investigations may provide valuable insights into potential applications in cattle health and the development of diagnostic tools for neurological disorders.
The third objective is to explore the potential applications of bovine NEFL in neurobiology and biotechnology. Research will investigate the use of bovine NEFL-expressing cells as models for studying neuronal-related diseases and for developing tissue engineering approaches for veterinary medicine and biotechnology.
By delving into the functions and roles of NEFL in bovine nervous tissues, this research aims to expand our knowledge of neuronal biology, its implications for veterinary medicine, and its potential applications in neurobiology and cattle health

Introduction
Epidermal growth factor has a profound effect on the differentiation of specific cells in vivo and is a potent mitogenic factor for a variety of cultured cells of both ectodermal and mesodermal origin. The EGF precursor is believed to exist as a membrane-bound molecule which is proteolytically cleaved to generate the 53-amino acid peptide hormone that stimulates cells to divide. EGF stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture. Long EGF is a recombinant analog of Human EGF developed as a replacement for use in therapeutic cell culture applications as a like-for-like supplement for Recombinant Human or native EGF.

Introduction
The term ‘PDGF’ refers to a family of disulphide bond-linked dimeric isoforms that act as autocrine and paracrine growth factors and are produced by a variety of cell types other than platelets.
They act as potent mitogens for almost all mesenchymally-derived cells. Aberrant expression is involved in certain cancers, fibroproliferative disorders and atherosclerosis. The protein also contributes to wound healing and neural regeneration. There are four members of the PDGF family – PDGF A, PDGF B, PDGF C and PDGF D. Two distinct types of PDGF-A exist – a short form that is soluble and a long form that is retained by the extracellular matrix.

Background
Tumor Necrosis Factor-alpha (TNF-α) is a pro-inflammatory cytokine that plays a critical role in the regulation of immune responses, inflammation, and cell survival. It is primarily produced by activated macrophages, but can also be secreted by other immune cells, such as T cells, natural killer cells, and mast cells. TNF-α is involved in a wide range of physiological and pathological processes, including the defense against infections, the development of autoimmune diseases, and the progression of cancer.
TNF-α exerts its effects by binding to two distinct cell surface receptors, TNF receptor 1 (TNFR1) and TNF receptor 2 (TNFR2). Upon binding to its receptors, TNF-α activates multiple signaling pathways, including the nuclear factor-kappa B (NF-κB) pathway, the mitogen-activated protein kinase (MAPK) pathway, and the apoptotic pathway. These signaling pathways regulate various cellular processes, such as inflammation, cell proliferation, differentiation, and apoptosis.
In the context of infections, TNF-α plays a crucial role in the body's defense against pathogens. It promotes the recruitment and activation of immune cells, enhances the production of other pro-inflammatory cytokines, and stimulates the expression of adhesion molecules on endothelial cells, facilitating the migration of immune cells to the site of infection. TNF-α also helps to induce fever, which is an important component of the body's immune response to infections.
However, excessive or prolonged production of TNF-α can contribute to the development of chronic inflammatory diseases, such as rheumatoid arthritis, inflammatory bowel disease, and psoriasis. In these conditions, elevated levels of TNF-α promote the infiltration of immune cells into the affected tissues, leading to tissue damage and the perpetuation of inflammation. The central role of TNF-α in the pathogenesis of these diseases has led to the development of anti-TNF-α therapies, which have revolutionized the treatment of chronic inflammatory diseases. These therapies include monoclonal antibodies, such as infliximab and adalimumab, and soluble TNF receptor fusion proteins, such as etanercept. Anti-TNF-α therapies have been shown to be effective in reducing inflammation, improving symptoms, and slowing disease progression in patients with chronic inflammatory diseases.
In the context of cancer, TNF-α has complex and context-dependent effects on tumor development and progression. On one hand, TNF-α can promote anti-tumor immunity by activating immune cells and stimulating the production of other pro-inflammatory cytokines. On the other hand, chronic inflammation driven by TNF-α can promote tumor growth, angiogenesis, and metastasis. Therefore, the role of TNF-α in cancer is still an area of active research, and the development of TNF-α-targeted therapies for cancer remains a challenge.
In conclusion, TNF-α is a pro-inflammatory cytokine that plays a critical role in the regulation of immune responses, inflammation, and cell survival. Its involvement in various physiological and pathological processes has made it an important target for the development of therapies for chronic inflammatory diseases and cancer. Anti-TNF-α therapies have revolutionized the treatment of chronic inflammatory diseases, but the complex role of TNF-α in cancer remains an area of ongoing research. Understanding the precise mechanisms by which TNF-α contributes to disease pathogenesis will be crucial for the development of more effective and targeted therapies.

More Info

Introduction
MCSFR which is also familiar as CSF1R, is part of the type3 subfamily of receptor tyrosine kinases. MCSFR is expressed mainly on cells of the monocyte and macrophage lineage, stem cells, and in the growing placenta. Most of the biological effects of this cytokine are mediated by MCSFR. MCSFR contains an extracellular ligand-binding domain, a single membrane-spanning segment, and an intracellular tyrosine kinase domain. Originally CSF1 and this receptor were implicated as vital for normal trophoblastic implantation as well as monocyte development. The role of CSF1/CSF1R in normal mammary gland development is actually very interesting since this connection has also been discovered in the biology of breast cancer with the results of abnormal expression of CSF1 and its receptor. Likewise, in Alzheimer's disease and after brain injuries an increased level of CSF1R was found in the microglia, which causes the microglia to become more active.

Introduction
PEDF is a neurotrophic protein that induces extensive neuronal differentiation in retinoblastoma cells. SerpinF1 is a potent inhibitor of angiogenesis. EPC1 doesn’t undergo the stressed to relaxed conformation transition characteristic as of the active serpins since it exhibits no serine protease inhibitory activity.
Aqueous humour level of asymmetric dimethylarginine is correlated with PEDF in humans. ADMA and PEDF levels are increased in response to inflammation in uveitis.
Lack of PEDF expression is a potent factor for the enhancement of tumor growth and angiogenesis in breast cancer.
PEDF & VEGF genes contribute to the development of diabetic retinopathy.
PEDF and VEGF structural changes in blood vessel wall play an important role in the pathophysiology of PD patients.
PEDF-overexpressing tumors exhibited reduced intratumoral angiogenesis.
SerpinF1 is a new promising approach for the treatment of osteosarcoma.
Levels of the natural ocular anti-angiogenic factor SentrinF1 (PEDF) is associated with proliferative retinopathy.
VEGF secreted by retinal pigment epithelial cells upregulates PEDF expression via VEGFR-1 in an autocrine manner.
Sentrin-F1 concentration in the aqueous humor of diabetic patients predicts who will develop progression of retinopathy.
PEDF blocks angiogenic effects of leptin through its anti-oxidative properties.

More Info

Introduction
TNFR1 belongs to the TNF-receptor superfamily. TNFR1 is a receptor for TNFSF2/TNF-alpha and homotrimeric TNFSF1/lymphotoxin-alpha.
There are 2 types of soluble TNF receptors: sTNFR-I and sTNFR-II, which act to neutralize the biological activities of TNF alpha and TNF beta. The levels of these soluble receptors seem to increase as a result of shedding of the extracellular domains of the membrane bound receptors. TNF-a, TNFR1 and TNFR2 have roles in cellular differentiation. TNFR1 and TNFR2 function in cell type-specific renal injury.
TNFR1 is capable of signaling both cell survival and apoptosis. TNFR1-induced apoptosis requires 2 sequential signaling complexes. TNFR1 is capable of activating NF-kappaB, mediate apoptosis, and function as a regulator of inflammation. Oxidative stress promotes TNFR1 and TNFR2 self-interaction, ligand-independent and enhanced ligand-dependent TNF signaling. TNFR1 contributes to the induction of non-cytocidal TNF effects including anti-viral state and activation of the acid sphingomyelinase. Human TNFR1 has a major region which controls cell surface expression. High levels of soluble TNF receptors are found in the amniotic fluid of pregnant women.
Germline mutations of the extracellular domains of TNFR1 are linked to the autosomal dominant periodic fever syndrome. The impaired receptor clearance is believed to be a mechanism of the disease. Familial hibernian fever (FHF) is caused by defects in TNFRSF1A gene.
