    • Introduction

      Eukaryotic Translation Initiation Factor 3F, also known as EIF3F belongs to the eIF-3 subunit F family. EIF3F is a component of the eukaryotic translation initiation factor 3 (eIF-3) complex, which isessential for several steps in the initiation of protein synthesis. The eIF-3 complex associates with the 40S ribosomeand facilitates the recruitment of eIF-1, eIF-1A, eIF 2: GTP: methionyl-tRNAi and eIF-5 to form the 43S preinitiationcomplex (43S PIC). In addition, the eIF-3 complex stimulates mRNA recruitment to the 43S PIC and scanning of the mRNA forAUG recognition. The eIF-3 complex is also necessary for disassembly and recycling of post termination ribosomalcomplexes and subsequently prevents premature union of the 40S and 60S ribosomal subunits prior to initiation. Among the diseases associated with EIF3F are intrahepatic cholangiocarcinoma, and cholangiocarcinoma.

    • Introduction

      CDNF is a member of the ARMET family and acts as a trophic factor for neurons. CDNF inhibits the (6-OHDA)-induced degeneration of neurons. When CDNF controlled after 6-OHDA-lesioning, it reestablishes the function and inhibits the degeneration of neurons in substantia nigra. CDNF is universally expressed in neuronal and non-neuronal tissues. The highest levels in the brain are found in the optic nerve and corpus callosum.

    • Background

      Cerebral Neurotrophic Factor Human Recombinant: A Leap Forward in Neurobiology

      The field of neurobiology is replete with wonder, particularly due to the influential role of neurotrophic factors. These essential proteins, responsible for the survival and growth of neurons, have become a focal point in modern research. Among these, the Cerebral Neurotrophic Factor (CNF) stands out, offering novel insights and potential breakthroughs in our understanding of neurological health.

      Enter the world of bioengineering, a scientific arena where we have successfully replicated CNF, leading to the birth of Cerebral Neurotrophic Factor Human Recombinant (CNF-HR). This is a massive step towards conquering neurodegenerative disorders such as Alzheimer's and Parkinson's diseases, conditions that have perplexed scientists and clinicians for decades.

      The extraordinary capacity of CNF-HR lies in its dual functionality - it acts as a defender and a promoter. It defends neurons from harmful degenerative processes while promoting their growth and development. Picture a devoted gardener who tirelessly protects his garden from pests and nurtures the growth of each plant. In this context, the brain is the vibrant garden, and the neurons, the delicate plants we must care for.

      Although this scientific breakthrough sparks enthusiasm, it's crucial to remember the challenges that lie ahead. The path to determining the most effective method of delivering CNF-HR to the brain, identifying the optimal dosage, and monitoring potential side effects is a winding one. Nevertheless, with continuous research and relentless scientific curiosity, we are optimistic about overcoming these challenges.

      In conclusion, the development of CNF-HR is a significant milestone in the fascinating journey of neurobiology. Its potential to change the trajectory of treating neurodegenerative diseases and enhancing our understanding of neuronal function is tremendous. While the journey is strewn with complexities, the potential rewards we stand to reap promise a future where neurodegenerative diseases could be effectively managed or even cured.

    More Info

    • Introduction

      GH is a member of the somatotropin/prolactin family of hormones which play an important role in growth control. The gene, along with four other related genes, is located at the growth hormone locus on chromosome 17 where they are interspersed in the same transcriptional orientation; an arrangement which is thought to have evolved by a series of gene duplications. The five genes share a remarkably high degree of sequence identity. Alternative splicing generates additional isoforms of each of the five growth hormones, leading to further diversity and potential for specialization. This particular family member is expressed in the pituitary but not in placental tissue as is the case for the other four genes in the growth hormone locus. Mutations in or deletions of the gene lead to growth hormone deficiency and short stature.

    • Introduction

      Galectin-4 is a member of the subfamily of galectins composed of two carbohydrate recognition domains having similar peptide chains. The galectins are a family of beta-galactoside-binding proteins having a role in modulating cell-cell and cell-matrix interactions, which inhibits chronic inflammations, GVHD, and allergic responses. LGALS4 expression is limited to small intestine, colon, and rectum, and it is underexpressed in colorectal cancer. LGALS4 binds as an endogenous ligand to glycosphingolipids having 3-O-sulfated Gal residues and bind as well to cholesterol-3-sulfate. LGALS4 takes part in cell adhesion. LGALS4 plays a role in crosslinking the lateral cell membranes of the surface-lining epithelial cells, thus supporting epithelial integrity against mechanical stress exerted by the bowel lume. LGALS4 is in charge of intestinal inflammation via selective regulation of peripheral and mucosal T-cell cell cycle, in addition to cell death by apoptosis of T-cells by a pathway independent of the activation of caspases. LGALS4 blockade decreases TNF-alpha inhibitor induced T-cell death. LGALS4 decreases pro-inflammatory cytokine secretion including IL-6 & IL-17.

    More Info

    • Introduction

      Endothelial cells express three different vascular endothelial growth factor (VEGF) receptors, belonging to the family of receptor tyrosine kinases (RTKs). They are named VEGFR-1 (Flt-1), VEGFR-2 (KDR/Flk-1), VEGFR-3 (Flt-4). Their expression is almost exclusively restricted to endothelial cells, but VEGFR-1 can also be found on monocytes. All VEGF-receptors have seven immunoglobulin-like extracellular domains, a single transmembrane region and an intracellular split tyrosine kinase domain. VEGFR-2 has a lower affinity for VEGF than the Flt-1 receptor, but a higher signaling activity. Mitogenic activity in endothelial cells is mainly mediated by VEGFR-2 leading to their proliferation.
      Differential splicing of the flt-1 gene leads to the formation of a secreted, soluble variant of VEGFR-1 (sVEGFR-1). No naturally occuring, secreted forms of VEGFR-2 have so far been reported. The binding of VEGF165 to VEGFR-2 is dependent on heparin.

    • 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.

    • Protein content

      Protein quantization was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.2 as the extinction coefficient for a 0.1% (1mg/ml) solution at pH 8.0. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).

    More Info

    • Introduction

      Galectins are a family of animal lectins with an affinity for beta-galactosides. This family has at least 14 identified members. Galectins share similarities in the CRD (the carbohydrate recognition domain). Galectins are synthesized as cytosolic proteins. Though localized principally in the cytoplasm and lacking a classical signal peptide, galectins can also be stimulated to secretion by non-classical pathways or alternatively targeted to the nucleus. Galectins are involved in modulating cell-cell and cell-matrix interactions. Human Galectin-7 belongs to the prototypical Galectins containing a single CRD, which is initially identified in human epidermis as a monomer. The Galectin-7 expression is induced by tumor suppressor protein p53 and associated with apoptosis. Galectin-7 is a pro-apoptotic protein which functions intracellularlly upstream of JNK activation and mitochondrial cytochrome c release. The correlation of Galectin-7 with the UV-induced apoptosis of keratinocytes presents a critical mechanism in the maintenance of epidermal homeostasis. Human Galectin-7 is localized in both nucleus and cytoplasm.

    More Info

    • Introduction

      MTHFS is a cytosolic protein which takes part in the formate metabolic process. MTHFS along with a magnesium cofactor catalyzes the ATP-dependent reaction which reduces 5-formyltetrahydrofolate (5-MTHF) to 5,10-methenyltetrahydrofolate(MTHF). MTHF is the substrate used by MTHFR (methylenetetrahydrofolate reductase) to generate 5-MTHF. In addition, MTHF is a coenzyme used in thymidine biosynthesis by thymidylate synthase (FAD).
