Introduction
Vimentin expression in human malignant glioma cells depends on cellular density, algorithms of drug delivery and chemo/radio treatment. Vimentin and detyrosinated microtubules provide structural support for the extensive microtentacles observed in detached tumor cells and a mechanism to promote successful metastatic spread. Primary colorectal carcinomas display aberrant expression of vimentin, and have activated Notch and TGFbeta signaling pathways. Vimentin is a strong arterial substrate for transglutaminases. Transglutaminase-mediated vimentin dimerization results in a novel unifying pathway by which vasodilatory and remodeling responses may be regulated. Ablation of vimentin expression inhibits migration and invasion of colon and breast cancer cell lines.

Introduction
Defensins are cationic peptides with a large spectrum of antimicrobial activity that comprise an important arm of the innate immune system. The Alpha defensins are differentiated from the Beta-defensins by the pairing of their 3 disulfide bonds.
4 human Beta-defensins have been identified to date; BD-1, BD-2, BD-3 and BD-4.
Beta-defensins are expressed on some leukocytes and at epithelial surfaces.
In addition to their direct antimicrobial activities, they are chemoattractant towards immature dendritic cells and memory T cells. The beta-defensin proteins are expressed as the C-terminal portion of precursors and are released by proteolytic cleavage of a signal sequence and, in the case of BD-1 (36 a.a.), a propeptide region. Beta-defensins contain a six-cysteine motif that forms three intra-molecular disulfide bonds. Beta-Defensins are 3-5 kDa peptides ranging in size from 33-47 amino acid residues. -

Background
Desmin, an intermediate filament protein, plays a fundamental role in maintaining the structural integrity and function of muscle cells. While extensive research has been conducted on desmin in mammals, the study of desmin in chickens is an emerging area with considerable potential for advancing our understanding of muscle biology. Chickens are valuable model organisms for studying muscle development, growth, and regeneration due to their relatively simple muscular system and economic significance in poultry production. This research aims to provide a comprehensive exploration of desmin in chickens, shedding light on its functions and implications for muscle structure and function.
The primary objective of this research is to elucidate the role of desmin in chicken muscle structure and development. In vitro and in vivo experiments, utilizing chicken cell cultures and embryonic models, will be conducted to investigate how desmin contributes to the organization of muscle fibers, sarcomere assembly, and myofibrillogenesis. Understanding these mechanisms is fundamental for deciphering the complexities of muscle development in chickens.
The second objective is to assess the clinical and economic relevance of desmin in poultry production. Studies involving broiler chickens will be conducted to evaluate the impact of desmin mutations or variations on muscle growth, meat quality, and disease susceptibility. These investigations may provide valuable insights into potential strategies for enhancing poultry production efficiency and meat quality.
The third objective is to explore the potential applications of desmin in biotechnology and tissue engineering. Research will investigate the use of desmin-expressing chicken cells as models for studying muscle-related diseases and for developing tissue engineering approaches for muscle repair and regeneration.
By delving into the functions and roles of desmin in chickens, this research aims to expand our knowledge of muscle biology, its implications for poultry production, and its potential applications in biotechnology and regenerative medicine.

Introduction
Ferritin is the main intracellular iron storage protein in prokaryotes and eukaryotes. Ferritin’s major functions are the storage of iron in a soluble and nontoxic state and its release in a controlled fashion. An iron-containing protein complex is found mostly in the intestinal mucosa, spleen, and liver. Ferritin is composed of 24 subunits of the heavy and light chains. Variation in ferritin subunit composition may influence the rates of iron uptake and release in different tissues. Defects in the light chain ferritin gene are linked to a number of neurodegenerative diseases and hyperferritinemia-cataract syndrome. The genes that encode the light and heavy chains are on located different chromosomes. The light chain genes are in chromosome region 19q13.3-q13.4 whilst those for the heavy chain are in chromosome region 11q12-q13. Ferritin is shaped like a hollow sphere, inside which the iron is stored in the Fe(III) oxidation state. The iron is integrated in the mineral ferrihydrite, [FeO(OH)]8[FeO(H2PO4)], which is attached to the inner wall of the sphere. To release iron once the body needs it, the iron must be altered from the Fe(III) to the Fe(II) oxidation state. Subsequently, the iron leaves through channels in the spherical structure. Therefore, the structure of ferritin is tremendously important for the protein's ability to store and release iron in a controlled mode.
The amount of ferritin in the blood (serum ferritin level) is directly related to the amount of iron stored in the body. The body has a "buffer" against iron deficiency (if the blood has too little iron, ferritin can release more) and, to a lesser extent, iron overload (if the blood and tissues of the body have too much iron, ferritin can help store the excess iron). -

Introduction
The protein encoded by this gene is a member of the glial cell line-derived neurotophic factor (GDNF) family of ligands which are a group of ligands within the TGF-beta superfamily of signaling molecules. GDNFs are unique in having neurotrophic properties and have potential use for gene therapy in neurodegenrative disease. Artemin has been shown in culture to support the survival of a number of periferal neuron populations and at least one population of dopaminergic CNS neurons. Its role in the PNS and CNS is further substantiated by its expression pattern in the proximity of these neurons. This protein is a ligand for the RET receptor and uses GFR-alpha 3 as a coreceptor. Four alternatively spliced transcripts have been described, two of which encode the same protein.

Background
Humanin, a small peptide derived from the mitochondrial genome, has emerged as a remarkable molecule with diverse cellular protective functions. This research paper aims to provide a comprehensive analysis of Humanin, exploring its biochemical properties, mechanisms of action, and potential therapeutic applications in various disease contexts.
Humanin, initially discovered for its role in neuroprotection, has since garnered interest for its broad spectrum of cytoprotective effects. Derived from the mitochondrial 16S ribosomal RNA, this small peptide plays a critical role in safeguarding cells from various stressors (Harvey, 2008). This paper delves into the complexities of Humanin, uncovering its multifaceted nature and potential clinical applications.
Humanin is a 24-amino acid peptide with a unique secondary structure that contributes to its cellular protective functions. It localizes to both the cytoplasm and mitochondria, where it interacts with various proteins involved in apoptotic and oxidative stress pathways (Hoang et al., 2019). Additionally, Humanin can undergo post-translational modifications, further diversifying its actions.
Humanin exerts its protective effects through multiple mechanisms. It interacts with the pro-apoptotic protein Bax, inhibiting its translocation to the mitochondria and preventing the release of cytochrome c (Hashimoto et al., 2001). Humanin also modulates the activities of caspases, key mediators of cell death pathways, thereby promoting cell survival in stressful conditions (Nakagawa et al., 2002).
Beyond its initial recognition as a neuroprotective agent, Humanin has demonstrated cytoprotective effects in various cell types, including cardiomyocytes, neurons, and endothelial cells (Chai et al., 2019). It attenuates oxidative stress, reduces mitochondrial dysfunction, and promotes cell viability, thereby safeguarding cells from a multitude of insults.
The multifaceted protective functions of Humanin offer promising therapeutic potential in various disease contexts. Research has shown its efficacy in mitigating neurodegenerative disorders, cardiovascular diseases, and age-related pathologies (Muzumdar et al., 2009). Furthermore, Humanin's ability to attenuate inflammation and promote tissue repair opens new avenues for therapeutic interventions.

Introduction
Cystatins are a superfamily of cysteine proteinase inhibitors found in both plants and animals. They comprise a group of proteinase inhibitors, widely distributed in tissues and body fluids, and form tight complexes with cysteine proteases such as cathepsin B, H, L and S. Cystatin C, a secreted molecule of this family, is of interest from biochemical, medicine and evolutionary points of view. Cystatin C, with molecular weight of 13260 Da, is composed of 120 amino acids, lacks carbohydrate and has two disulfide bridges located near the carboxyl terminus. Cystatin C is increased in patients with malignant diseases, and is related to the insufficiency of renal function and appears to be a better marker than creatinine. On the other hand, low levels of cystatin C involve cause the breakdown of the elastic laminae and, subsequently, the atherosclerosis and abdominal aortic aneurysm.

Introduction
Terlipressin is similar to a naturally occurring hormone present in the body, known as antidiuretic hormone (ADH) or vasopressin. ADH has two main effects in the body. Firstly, it causes narrowing of blood vessels (vasoconstriction), thereby limiting blood flow to a particular area of the body. It also acts on receptors in the kidney to retain water in the body, which helps to prevent excessive loss of water in the urine. Terlipressin is commonly used to stop bleeding of varices in the food pipe (oesophagus). Varices are fragile distended veins that can occur in various parts of the body such as the oesophagus. This is caused by an increase in blood pressure in certain diseases such as severe liver disease. These fragile varices can rupture and lead to life threatening bleeding. Terlipressin is therefore given to narrow blood vessels, and so restricting blood flow to the varices and stopping the bleeding.

Introduction
Anti-Mullerian Hormone also known as AMH is a member of the TGF-beta family. AMH is a glycoprotein which is produced by the Sertoli cells of the testis, causes regression of the Muellerian duct. AMH inhibits the growth of tumors derived from tissues of Muellerian duct origin. Moreover, AMH participates in Leydig cell differentiation and function in addition to follicular development in adult females.

Introduction
SERPINA1 is secreted and is a serine protease inhibitor which its targets include elastase, plasmin, collagenase, thrombin, leucocytic proteases, trypsin, chymotrypsin, and plasminogen activator. Defects in SERPINA1 gene can cause emphysema or liver disease. Antral SERPINA1 expression is particularly induced by H. pylori infection. lung and prostate cancers have shown a significant increase in SERPINA1 serum levels compared with healthy controls though breast cancers did not show a significant change. SERPINA1 is an endogenous inhibitor of serine proteases and inhibits the catalytic domain of human recombinant matriptase in vitro. Rise in SERPINA1 occurs as an acute phase response to tissue necrosis and inflammation. mutations in SERPINA1 and SLC11A1 genes change the balance between elastase produced by leukocytes during phagocytosis.

Introduction
Cystatins are a superfamily of cysteine proteinase inhibitors found in both plants and animals. They comprise a group of proteinase inhibitors, widely distributed in tissues and body fluids, and form tight complexes with cysteine proteases such as cathepsin B, H, L and S. Cystatin C, a secreted molecule of this family, is of interest from biochemical, medicine and evolutionary points of view. Cystatin C is increased in patients with malignant diseases, and is related to the insufficiency of renal function and appears to be a better marker than creatinine. On the other hand, low levels of cystatin C involve cause the breakdown of the elastic laminae and subsequently, the atherosclerosis and abdominal aortic aneurysm.
