Endothelin-1 Signaling Endothelin-1 Signaling Monday, April 23, 2018
Cardiac hypertrophy describes an abnormal condition where the heart becomes enlarged. Several factors, such as increased mechanical loading and neuro-hormonal chemicals can induce hypertrophy. ET1 (Endothelin-1) is a 21-amino acid vasoconstrictor peptide, which is able to induce cardiac hypertrophy.
Pathogenesis of ALS Pathogenesis of ALS Sunday, April 22, 2018
ALS (Amyotrophic Lateral Sclerosis), also known as Lou Gehrig’s disease, is a devastating neurodegenerative disorder, which is characterized by the selective degeneration of upper and lower motor neurons, the large nerve cells connecting the brain to the spinal cord and from the spinal cord to muscles, which control muscle movement.
Cholera Infection Cholera Infection Friday, April 20, 2018
Cholera is one of the most severe diarrheal diseases that affect humans and is responsible for significant morbidity and mortality especially among children in developing countries. It is characterized by numerous, voluminous watery stools, often accompanied by vomiting, and resulting in hypovolemic shock and acidosis. It is caused by certain members of [...]
Activation of PKC through GPCR Activation of PKC through GPCR Thursday, April 19, 2018
PKC (Protein Kinase-C) is a cyclic nucleotide-independent enzyme that phosphorylates serine and threonine residues in many target proteins. PKC plays a pivotal role in mediating cellular responses to extracellular stimuli involved in proliferation, differentiation, apoptosis, and exocytotic release in a number of non-neuronal systems such as Islet cells, Chromaffin cells and Paramecium. [...]
nNOS Signaling in Skeletal Muscle nNOS Signaling in Skeletal Muscle Thursday, April 19, 2018
NO (Nitric Oxide) is formed endogenously by a family of enzymes known as NOS (NO Synthases). The distribution of different isoforms of NOS is largely related to their respective functions. Three distinct isoforms of NOS have been identified: nNOS (also known as NOSI and NOS-1) being the isoform first found (and predominating) [...]
EGF Pathway EGF Pathway Wednesday, April 18, 2018
Angiogenesis, the growth of new blood vessels, plays a key role in many physiological and pathological processes, such as ovulation, embryo-genesis, wound repair, inflammation, malignant tumor growth, retinopathies, rheumatoid arthritis, and angiogenesis-dependent diseases. One of the best-characterized modulators of angiogenesis is the heparin-binding FGF(Fibroblast Growth Factor).
Pancreatic Adenocarcinoma Pancreatic Adenocarcinoma Wednesday, April 18, 2018
Pancreatic carcinoma is one of the most enigmatic and aggressive malignant diseases. Neoplasms of the pancreas encompass a wide spectrum of benign and malignant tumors. Pancreatic adenocarcinoma, the malignant neoplasm of the exocrine duct cells, accounts for more than ninety percent of all pancreatic tumors
p53 Signaling p53 Signaling Thursday, April 12, 2018
p53 is a tumour suppressor protein that regulates the expression of a wide variety of genes involved in Apoptosis, Growth arrest, Inhibition of cell cycle progression, Differentiation and accelerated DNA repair or Senescence in response to Genotoxic or Cellular Stress. As a transcription factor, p53 is composed of an N-terminal Activation Domain, [...]
