Background
Vasoactive Intestinal Peptide (VIP), a prominent member of the glucagon-secretin peptide superfamily, plays a multifaceted role as a neuropeptide and neurotransmitter. This research paper aims to provide an extensive analysis of VIP, exploring its biochemical properties, diverse physiological functions, and potential therapeutic applications in various disease conditions.
Vasoactive Intestinal Peptide (VIP), originally identified for its potent vasodilatory properties in the gastrointestinal system, has since been recognized for its wide-ranging physiological effects throughout the body. As a neuropeptide and neurotransmitter.
VIP, a 28-amino acid peptide, exhibits a diverse range of biological activities due to its interactions with multiple G protein-coupled receptors (GPCRs) from the VIP/PACAP receptor family (Harmar et al., 2012). These receptors are expressed in various tissues and cells, enabling VIP to exert its pleiotropic effects.
VIP is involved in the regulation of numerous physiological processes. It functions as a potent vasodilator, modulates smooth muscle activity in the gastrointestinal tract, and participates in neurotransmission in the central and peripheral nervous systems (Lelievre et al., 2008). Additionally, VIP has immunomodulatory properties, influencing immune cell functions and inflammatory responses (Delgado et al., 2004).
VIP serves as a neurotransmitter in the central nervous system, where it contributes to various neuronal functions, including learning, memory, and sensory perception (Deng et al., 2015). Moreover, VIP has demonstrated neuroprotective effects in neurodegenerative disorders, making it a potential therapeutic target for neuroprotection and neuroregeneration (Delgado et al., 2002).
VIP's diverse physiological functions offer potential therapeutic applications in various disease contexts. Research has explored its potential in the treatment of inflammatory diseases, neurodegenerative disorders, and gastrointestinal disorders (Delgado et al., 2013). Furthermore, VIP-based therapies are being investigated for their neuroprotective potential in brain injuries and stroke.
As the research on VIP continues to progress, further investigation is warranted to uncover the precise mechanisms of action and potential clinical applications in medicine. VIP stands as a remarkable example of a neuropeptide with extensive physiological roles and therapeutic potential in various disease conditions.

Introduction
Prolactin is a lactogenic hormone secreted by the adenohypophysis .Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation.Prolactin has been shown also to have cytokine-like activities and to have important immunoregulatory activities. It contributes to the development of lymphoid tissues and the maintenance of physiological immune function and also modulates a variety of T-cell immune responses. Prolactin has been reported to activate cellular proliferation in nonreproductive tissue, such as liver, spleen, and thymus. It induces significant proliferation in aortic smooth muscle cells and also enhances proliferation of these cells induced by PDGF . Prolactin also appears to be directly mitogenic for pancreatic beta cells. Prolactin is also mitogenic for cultured astrocytes.

Introduction
PMSG Hormone is a well know used hormone together with progestogen to increase ovulation just before to artificial insemination. PMSG hormone is a placental glycoprotein produced from the serum of pregnant mares. PMSG comprises of an alfa subunit and a beta subunit. PMSG hormone is secreted from endometrial cups within the pregnant mare uterus aging from 40 to 130 days into their maturation, and once extracted, it can been used to promote artificially estrus in female animals. These assemblies produce PMSG hormone to induce mare's ovarian and repsouctive structures. PMSG can induce the growth of follicles by ovaries and results in ovulatation. PMSG hormone has an about a 4 day half-life of bioactivity in species other than horses. The extended biological activity can cause ovarian stimulation and ovulation. However, PMSG use alone often causes cystic ovarian disease because of the unrestrained ovarian stimulation and due to the sugar molecules which decrease clearance of the hormone. PMSG is more likely to be used than other pituitary hormones due to the extended circulatory half-life. PMSG solely exhibits luteinizing hormone like activity, however in other animal classes it has FSH & LH like activity.

Background
Leptin is a hormone which takes part in regulating body weight, metabolism and reproductive function and is encoded by the obese gene. Leptin is expressed predominantly by adipocytes, which fits with the idea that body weight is sensed as the total mass of fat in the body. Smaller amounts of leptin are also secreted by cellsin the epithelium of the stomach and in the placenta. Leptin receptors are expressed mainly in areas of the hypothalamus which regulates body weight, as well as in T lymphocytes and vascular endothelial cells.

Background
Leptin is mainly produced by adipocytes. Leptin’s main part is to regulate long-term energy balance. Leptin is encoded by the LEP gene. Leptin effects mostly on leptin receptors in the cell mambrane of various cells in the human body. The leptin receptor can be found on a various cell types. The leptin receptor is a single-transmembrane-domain type 1 cytokine receptor. leptin levels influence satiety, appetite and triggers behaviours which save energy. High leptin levels are interpreted by the brain that energy reserves are high, whereas low leptin levels means that energy reserves are low, in the process adapting the organism to starvation through a variety of metabolic, neurobiochemical, endocrine and behavioral change.

Introduction
Exedin-4 Recombinant is a like peptide-1 receptor agonist. The native hormone is produced in the gut of Gila monster Heloderma suspectrum (a type of reptile found in the desert) that stimulates production without causing threateningly low blood sugar, which can occur after using some anti-diabetes products. Recently, researchers used extracted saliva from gila monsters to create an unprecedented breakthrough in Diabetes Type 2 treatment. Unlike other products taken for type 2 diabetes, Exedin-4 has not been linked with weight gain and actually resulted in weight loss, according to the researchers. Exedin-4 enhances glucose-dependant secretion, suppresses inappropriately elevated secretion and slows gastric emptying in vivo. It also promotes B-cell proliferation and neogenesis in vitro and in animal models. Exedin-4 stimulates an increase in acinar cAMP, without stimulating the release of amylase.

Introduction
Gankyrin (proteasome 26S subunit) is a multicatalytic proteinase oncoprotein commonly overexpressed in most hepatocellular carcinomas. Proteasomes are found throughout eukaryotic cells at a high concentrations and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. Gankyrin interacts with S6 ATPase of the 19S regulatory particle of the 26S proteasome. Gankyrin is involved in theregulation of the phosphorylation of the retinoblastoma protein by CDK4, and to enhance the ubiquitinylation of p53 by MDM2. Gankyrin consists of 7 ankyrin repeats and is structurally similar to I kappa Bs. Gankyrin acts as a regulatory subunit of the 26s proteasome which is involved in the atp-dependent degradation of ubiquitinated proteins. Gankyrin is involved in progression of esophageal squamous cell carcinoma. gankyrin plays an oncogenic role especially in early stages of human epatocarcinogenesis. Gankyrin binds to NF-kappaB and suppresses its activity at the transcription level by modulating acetylation through SIRT1. Structural comparison between Gankyrin & p16(INK4A) identified numerous residues of gankyrin that are potentially important for CDK4 binding.

Introduction
NNMT is part of the family of transferases, especially those transferring one-carbon group methyltransferases. NNMT is mostly expressed in the liver, and a lower expression is seen in the kidney, lung, skeletal muscle, placenta and heart. NNMT catalyzes the N-methylation of nicotinamide and other pyridines to form pyridinium ions. This activity is significant for biotransformation of many drugs and xenobiotic compounds. NNMT is accountable for the enzymatic activity which uses S-adenosyl methionine as the methyl donor. NNMT expression is related with tumor stage and DFS time in hepatocellular carcinoma cases. NNMT is a good candidate as a tumor marker of various kinds of cancers. NNMT serum levels have significance in the premature detection and in the management of patients with colorectal cancer.

Introduction
Avidin is a tetrameric protein of 4 identical subunits (homotetramer) each of which can bind to biotin with a high degree of affinity and specificity. Avidin molecular weight in its tetrameric form is estimated to be between 66-69 kDa. Avidin is produced in the oviducts of birds, reptiles and amphibians and is subsequently deposited in the whites of their eggs. In the chicken egg white, avidin makes up roughly 0.05% of total protein (approximately 1.8 mg per egg). 10% of Avidin’s molecular weight is ascribed to carbohydrate content which is composed of four to five mannose and three N-acetylglucosamine residues. Avidin has at least three distinctive oligosaccharide structural type which are similar in structure and composition. The dissociation constant (KD) of avidin is approximately 10-15M, making it one of the strongest known non-covalent bonds.

Background
Research has demonstrated that osteocrin influences bone formation by enhancing the anabolic effects of osteoblasts, the cells responsible for new bone formation. In addition to its skeletal roles, osteocrin has been shown to regulate cardiovascular functions by modulating blood pressure and cardiac hypertrophy. Furthermore, emerging evidence suggests that osteocrin may play a role in the central nervous system, impacting cognitive function and neuroprotection.

Introduction
"Epiregulin is part of the EGF family. Epiregulin functions as a ligand of EGFR, as well as a ligand of most members of the ERBB (v-erb-b2 oncogene homolog) family of tyrosine-kinase receptors.Epiregulin is expressed mostly in the placenta and peripheral blood leukocytes and in specific carcinomas of the bladder, lung, kidney and colon. Epiregulin stimulates the proliferation of keratinocytes, hepatocytes, fibroblasts and vascular smooth muscle cells. Epiregulin inhibits the growth of several tumor-derived epithelial cell lines. Human Epiregulin is initially synthesized as a glycosylated 19.0 kDa transmembrane precursor protein, which is processed by proteolytic cleavage to produce a 6.0 kDa mature secreted sequence."
