Ulcerative colitis (UC) is a disease of colon or large intestine, which leads to inflammation of the colon and development of tiny sores that produce mucous or pus. The disease happens due to dysfunction of immune system.
Constipation refers to an irregular bowel movement, which is characterized by lumpy and hard stool, pain in passing the stool, and feeling of incomplete emptying. Additional implications of constipation include hemorrhoids anal fissure, rectal prolapse, and fecal imprecation.
IL-6 is transcribed by IL-6 gene that encodes a cytokine, which functions in inflammation and maturation of B cells. The IL-6 protein can induce fever in patients suffering from autoimmune diseases, thereby acting as endogenous pyrogens.
JAK consists of four intracellular non-receptor tyrosine kinases that help in cytokine mediated signaling through the JAK-STAT pathway. It contains two almost identical phosphate transferring domains in which one domain shows kinase activity and the other regulates the activity of the first via negative inhibition.
Mitochondria (singular: mitochondrion) are cytoplasmic organelles found in eukaryotic cells, such as plants, animals, fungi, and protists. The number of mitochondria present in a eukaryotic cell depend on the metabolic requirements of that cell; and ranges from a single large mitochondrion to thousands of the organelles.

Nav1.7 voltage-gated sodium channel inhibitors are the drug candidates that target the sodium channels Nav1.7 and have been significant in pain management. The sodium channels Nav1.7 receptors are generally found in two types of neurons: nociceptive pain neurons, such as trigeminal neurons and dorsal root ganglion; and sympathetic ganglion neurons which form a part of the autonomic (involuntary) nervous system. These receptors play an important role in generation and conduction of action potential.
Cyclophilin befits in the group of protein that shows peptidyl-prolyl cis-trans isomerase activity, found in all types of cells. In humans, 16 cyclophilins have been identified till date. Cyclophilin A, a member of cyclophilin group, mediate the action of immunosuppressive drugs.
Cell cycle inhibitors include cyclin inhibitors and cyclin-dependent kinases (CDKs), which plays major role in developing new class of anti-cancer therapies. Also, cell cycle inhibitors in combination with chemotherapy, overcome drug resistance and improve cytotoxic efficacy. CDKs are rational targets for cancer treatment, that could restore cell-cycle checkpoints and may induce apoptosis.
Aurora kinase are proteins that function as mitotic regulators and are aberrantly expressed in cancerous cells. Aurora kinase inhibitors target these aberrantly expressed regulators, provides genetic stability and prevents tumorigenesis.
Adenosine 5-monophosphate activated protein kinase (AMPK) plays an important role in regulation of homeostasis. Dysregulation of AMPK can result in many diseases which includes obesity and type 2 diabetes. Several studies have also suggested that AMPK are also associated with the development of neurological diseases and cancer.
Androgens are responsible for the development of male characteristics by binding to androgen receptors. Androgen receptor plays an important role in the development and progression of prostate cancer. Thus, it has been an attractive target for the clinical interventions and treatment of prostate cancer.
Alpha-synuclein is a protein that is abundantly found in the brain. The minimal amount of alpha-synuclein is also found in the heart and other tissues. The protein is prominently found at the tips of the nerve cells. It helps in the maintaining supply of the synaptic vesicle in presynaptic terminals. In addition, the alpha-synuclein protein also helps in release of dopamine.
Proctitis is characterized by the inflamed lining tissue of the inner rectum due to several medical conditions. The common causes of proctitis are sexually-transmitted infections (STIs), inflammatory bowel diseases (ulcerative colitis and Crohn’s disease), anal trauma, rectal infections, and radiation therapy for ovarian, anal, rectal, or prostate cancer.
Pouchitis is an inflammatory disorder that develops when the ileal pouch becomes inflamed and irritated. Increased bowel frequency, bloody stool, incontinence, straining during defecation, tenesmus, lower abdominal pain and abdominal cramping or bloating are some of the problems observed in pouchitis.
Postoperative ileus is defined as malfunctioning of intestinal motility after major abdominal surgeries. It generally affects large number of patients who are undergoing bowel resection surgery which causes significant discomfort and extend hospital stay. Postoperative ileus affects small intestine, stomach and large intestine. The disease is broadly categorized into primary and secondary type.
Opioid-induced bowel dysfunction occurs due to excessive consumption of opioids to manage pain. Opioid is generally use in the clinical management of pain which affects gastrointestinal tract and causes several types of side-effects. Opioid induced constipation is the most common side-effect occur due to excessive usage of opioids.
Hyperinsulinemia is a medical condition which is characterized by increased amount of insulin in blood. The primary cause of the disease is insulin resistance, which can also result in the development of type 2 diabetes. Insulinoma and nesidioblastosis are some other causes of hyperinsulinemia.
Hepatorenal syndrome (HRS) is a reversible functional renal impairment, that occurs in patients with advanced liver cirrhosis or those with fulminant hepatic failure. It is characterized by a marked reduction in glomerular filtration rate and renal plasma flow, in the absence of other causes of renal failure.
