Introduction
Prealbumin is a thyroid hormone-binding protein that transports thyroxine from the bloodstream to the brain. Prealbumin is a carrier protein which transports thyroid hormones in the plasma and cerebrospinal fluid, and also transports retinol (vitamin A) in the plasma. Transthyretin consists of a tetramer of identical subunits and is dominantly produced in the liver. Mutations in Prealbumin are related to amyloid deposition, affecting predominantly peripheral nerve and/or the heart. The diseases caused by mutations include amyloidotic polyneuropathy, euthyroid hyperthyroxinaemia, amyloidotic vitreous opacities, cardiomyopathy, oculoleptomeningeal amyloidosis, meningocerebrovascular amyloidosis, and carpal tunnel syndrome. Prealbumin is an indicator of protein-energy malnutrition since it has a circulating half life of 2 days and reacts swiftly to changes in nutritional status.

Introduction
Ferritin is a fairly large, iron-storage heteropolymeric protein composed of 2 subunit types, light Ferritin & heavy Ferritin polypeptides, which is expressed in most kinds of cells and co-assemble in different proportion in a tissue-specific manner. Ferritin is composed of 24 self-assembled polypeptide subunits of the heavy and light ferritin chains and is characterized by the capacity to remove Fe from solution in the presence of oxygen.
Ferritin light polypeptide protein is the main intracellular iron storage protein in prokaryotes and eukaryotes. Variation in ferritin subunit composition influence the rates of iron uptake and release in various tissues. A key function of ferritin is the storage of iron in a soluble and nontoxic state. Defects in this light chain ferritin gene are associated with several neurodegenerative diseases and hyper ferrit anemia-cataract syndrome.
Ferritin stores iron in a soluble, nontoxic, readily accessible form. Ferritin is needed for iron homeostasis. Iron is taken up in the ferrous form and deposited as ferric hydroxides after it has been oxidized. -

Introduction
HCV is a small 50nm, enveloped, single-stranded, positive sense RNAvirus in the family Flaviviridae.
HCV has a high rate of replication with approximately one trillion particles produced each day in an infected individual. Due to lack of proofreading by the HCV RNA polymerase, the HCV has an exceptionally high mutation rate, a factor that may help it elude the host's immune response. Hepatitis C virus is classified into six genotypes(1-6) with several subtypes within each genotype. The preponderance and distribution of HCV genotypes varies globally. Genotype is clinically important in determining potential response to interferon-based therapy and the required duration of such therapy. Genotypes 1 and 4 are less responsive to interferon-based treatment than are the other genotypes (2, 3, 5 and 6). -

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
Lysyl Oxidase also known as LOX is an extracellular copper enzyme which initiates the crosslinking of collagens and elastin. LOX catalyzes oxidative deamination of the epsilon-amino group in certain lysine and hydroxylysine residues of collagens and lysine residues of elastin. Adding up to crosslinking extracellular matrix proteins, LOX plays a part in tumor suppression. Moreover, defects in LOX are the cause of autosomal recessive cutis laxa type I, CL type I. Two transcript variants encoding dissimilar isoforms have been found for LOX.

Introduction
Cyclin B1 (CCNB1) is a regulatory protein involved in mitosis. CCNB1 creates a complex with p34(cdc2) to form the maturation-promoting factor (MPF). CCNB1 is vital for the control of the cell cycle at the G2/M (mitosis) transition. CCNB1 builds up steadily during the G2 and is immediately destroyed at mitosis. The 2 alternative transcripts produce a constitutively expressed transcript and a cell cycle-regulated transcript which is expressed predominantly during G2/M phase. These transcripts are a result of alternate transcription initiation sites.

Introduction
Eotaxin-2, also called MPIF2 & Ckb6, is a novel CC chemokine produced by activated monocytes and T lymphocytes. Eotaxin-2 selectively chemoattracts cells expressing CCR3 including eosinophils, basophils, Th2 T cells, mast cells, and certain subsets of dendritic cells. Furthermore, Eotaxin-2 inhibits the proliferation of multipotential hematopoietic progenitor cells. The mature protein, which includes C-terminal truncation, contains 78 amino acids (92 amino acids for the mouse homolog, without C-terminal truncation).
CCL24 functions as a chemotactic chemokine for resting t-lymphocytes, and eosinophils. CCL24 has lower chemotactic activity for neutrophils but none for monocytes and activated lymphocytes. CCL24 is a strong suppressor of colony formation by a multipotential hematopoietic progenitor cell line and binds to CCR3. -

Introduction
GCSF is a cytokine that controls the production, differentiation, and function of granulocytes. The active protein is found extracellularly. Three transcript variants encoding three different isoforms have been found for the GCSF gene. Granulocyte/macrophage colony-stimulating factors are cytokines that act in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages. This csf induces granulocytes.

Introduction
XCL1 is a small cytokine belongs to the XC chemokine family that is also known as lymphotactin. XCL1 is found in high levels in spleen, thymus, intestine and peripheral blood leukocytes, and at lower levels in lung, prostate gland and ovary. Cellular sources for XCL1 include activated thymic and peripheral blood CD8+ T cells. This chemokine attracts T cells. In humans, XCL1 is closely related to XCL2, whose gene is found at the same locus on chromosome 1. XCL1 induces it chemotactic function by binding to a chemokine receptor called XCR1.
