    • Introduction

      proBDNF (the precursor form of Brain-derived neurotrophic factor) interacts preferentially with p75NTR (the pan-neurotrophin receptor p75) and vps10p domain-containing receptor sortilin and induces neuronal apoptosis, while the mature BDNF selectively binds with great affinity to the TrkB kinase receptor and promotes the survival, growth and differentiation of neurons. Since proneurotrophins and mature neurotrophins bring forth opposite biological effects, proBDNF cleavage in the neuronal system is regulated in a specific and cell-context dependent manner. proBDNF has an important role in negative regulation of neurotrophic actions in the brain.

    • Introduction

      Connective Tissue Growth Factor is a part of the CCN family of proteins. The CCN family presently consists of six members in human also known as: Cyr61 (Cystein rich 61), CTGF, Nov (Nephroblastoma Overexpressed gene), WISP-1, 2 and 3 (Wnt-1 Induced Secreted Proteins). CCN proteins are matricellular proteins which are involved in the regulation of various cellular functions including: proliferation, differentiation, survival, adhesion and migration. They are expressed in derivatives of the three embryonic sheets and are implicated in the development of kidney, nervous system, muscle, bone marrow, cartilage and bone. During adulthood, they are implicated in wound healing, bone fracture repair, and pathologies such as: tumorigenesis,fibrosis and vascular ailments. Full length secreted CCN proteins can show an antiproliferative activity, whereas truncated isoforms are likely to stimulate proliferation and behave as oncogenes.
      The full length protein consists of 4 modules: Module I shares partial identity with the N-terminal part of the Insulin-like Growth Factor Binding Proteins (IGFBPs).
      Module II includes a stretch of 70amino acid residues – which shares sequence identity with the Von Willebrand Factor Type C repeat (VWC).
      Module III contains sequences sharing identity with the Thrombospondin type 1 repeat (TSP1) (WSXCSXXCG), which is thought to be implicated in the binding of sulfated glycoconjugates and to be important for cell adhesion.
      Module IV, also designated CT, is encoded by exon5. It is the leasts conserved one of the four domains at the level of nucleotide sequence, but it appears to be critical for several of the biological functions attributed to the CCN proteins.
      Proteolysis of the secreted full-length CCN proteins that has been reported in the case of CCN2 and CCN3 might result in the production of CCN-derived peptides with high affinity for ligands that full-length CNN proteins bind only poorly. Amino-truncated CCN2 isoforms were biologically active whereas no specific biological activity has been attributed to the truncated CCN3. Although the molecular processes underlying the production of these secreted isoforms is presently unknown, it is important to note that proteolysis occur at the same amino acid residues in both CCN2 and CCN3. An elevated expression of CCN2 has also been detected by Northern blotting in human invasive mammary ductal carcinomas, dermatofibromas, pyogenic granuloma, endothelial cells of angiolipomas and angioleiomyomas, and in pancreatic tumors. A study performed with chondrosarcomas representative of various histological grades established that CCN2 expression was closely correlated with increasing levels of malignancy.
      In agreement with CCN2 playing a role in brain tumor angiogenesis, immunocytochemistry studies indicated that both glioblastoma tumor cells and proliferating endothelial cells stained positive for CCN2. In astrocytomas, CCN2 expression was particularly elevated in high grade tumors, with a marked effect of CCN2 on cell proliferation. Downregulation of CCN2 expression in these cells was associated with a growth arrest at the G1/S transition while over-expression of CCN2 induced a two-fold increase of the number of cells in the G1 phase. Gene profiling analysis allowed to identify a set of about 50 genes whose expression might account for the proliferative activity of CCN2 in these cells.
      CCN2 was seen in a higher proportion of mononuclear cells of patients with acute lymphoblastic leukemia.

    • Introduction

      Eukaryotic translation initiation factor 3, subunit I (EIF3I) is part of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is essential for numerous steps in the initiation of protein synthesis. The eIF-3 complex links with the 40S ribosome and facilitates the recruitment of eIF-1, eIF-1A, eIF-2: GTP: methionyl-tRNAi and eIF-5 to form the 43S pre-initiation complex (43S PIC). The eIF-3 complex stimulates mRNA recruitment to the 43S PIC and scanning of the mRNA for AUG recognition. The eIF-3 complex is also essential for disassembly and recycling of post-termination ribosomal complexes and subsequently prevents premature joining of the 40S and 60S ribosomal subunits prior to initiation. Among the diseases associated with EIF3I are clonorchiasis, and tonsillitis.

    • Introduction

      The Trefoil Factor peptides (TFF1, TFF2 and TFF3) are stable secretory proteins expressed in the gastrointestinal tract (gastric mucosa), and are involved in intestinal mucosal defense and repair. TFF1 is an essential protein for normal differentiation of the antral and pyloric gastric mucosa and functions as a gastric-specific tumor suppressor gene. TFF1 is a stabilizer of the mucous gel overlying the gastrointestinal mucosa that provides a physical barrier against various noxious agents. TFF1 protects the mucosa from isults, stabilizes the mucus layer, & affects healing of the epithelium. TFF1 is commonly expressed in tumors. TFF1 is related with the cell membrane of MCF-7 cells. High levels of TFF1 and TFF2 are found in serum from inflammatory bowel disease.

    • 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/ macrophagemigration, 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 mitogenesisand 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 are linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy.

    • Introduction

      Tumor necrosis factor is a cytokine involved in systemic inflammation and is a member of a group of cytokines that all stimulate the acute phase reaction. TNF is mainly secreted by macrophages.
      TNF causes apoptotic cell death, cellular proliferation, differentiation, inflammation, tumorigenesis and viral replication, TNF is also involved in lipid metabolism, and coagulation. TNF's primary role is in the regulation of immune cells.
      Dysregulation and, in particular, overproduction of TNF have been implicated in a variety of human diseases- autoimmune diseases, insulin resistance, and cancer.

    • 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.
