Pancreatitis is a condition characterized by inflammation of the pancreas. The pancreas is a large organ behind the stomach that produces digestive enzymes and a number of hormones. There are two main types: acute pancreatitis, and chronic pancreatitis.
Pancreatic cancer arises when cells in the pancreas, a glandular organ behind the stomach, begin to multiply out of control and form a mass. These cancerous cells have the ability to invade other parts of the body. A number of types of pancreatic cancer are known.
Glial fibrillary acidic protein (GFAP) is a protein that is encoded by the GFAP gene in humans. It is a type III intermediate filament (IF) protein that is expressed by numerous cell types of the central nervous system (CNS), including astrocytes and ependymal cells during development. GFAP has also been found to be expressed in glomeruli and peritubular fibroblasts taken from rat kidneys, Leydig cells of the testis in both hamsters and humans, human keratinocytes, human osteocytes and chondrocytes and stellate cells of the pancreas and liver in rats.
The CD44 antigen is a cell-surface glycoprotein involved in cell–cell interactions, cell adhesion and migration. In humans, the CD44 antigen is encoded by the CD44 gene on chromosome 11. CD44 has been referred to as HCAM, Pgp-1, Hermes antigen, lymphocyte homing receptor, ECM-III, and HUTCH-1.
The prolactin receptor (PRLR) is a type I cytokine receptor encoded in humans by the PRLR gene on chromosome 5p13-14. It is the receptor for prolactin (PRL). The PRLR can also bind to and be activated by growth hormone (GH) and human placental lactogen (hPL). The PRLR is expressed in the mammary glands, pituitary gland, and other tissues. It plays an important role in lobuloalveolar development of the mammary glands during pregnancy and in lactation.
The glucagon receptor is a 62 kDa protein that is activated by glucagon and is a member of the class B G-protein coupled family of receptors, coupled to G alpha i, Gs and to a lesser extent G alpha q. Stimulation of the receptor results in the activation of adenylate cyclase and phospholipase C and in increased levels of the secondary messengers intracellular cAMP and calcium. In humans, the glucagon receptor is encoded by the GCGR gene.
Cluster of differentiation 97 is a protein also known as BL-Ac[F2] encoded by the ADGRE5 gene. CD97 is a member of the adhesion G protein-coupled receptor (GPCR) family. Adhesion GPCRs are characterized by an extended extracellular region often possessing N-terminal protein modules that is linked to a TM7 region via a domain known as the GPCR-Autoproteolysis INducing (GAIN) domain.
Integrin beta-6 is a protein that in humans is encoded by the ITGB6 gene. It is the β6 subunit of the integrin αvβ6. Integrins are αβ heterodimeric glycoproteins which span the cell’s membrane, integrating the outside and inside of the cell. Integrins bind to specific extracellular proteins in the extracellular matrix or on other cells and subsequently transduce signals intracellularly to affect cell behaviour. One α and one β subunit associate non-covalently to form 24 unique integrins found in mammals. While some β integrin subunits partner with multiple α subunits, β6 associates exclusively with the αv subunit. Thus, the function of ITGB6 is entirely associated with the integrin αvβ6.
Fibroblast activation protein alpha (FAP-alpha) also known as prolyl endopeptidase FAP is an enzyme that in humans is encoded by the FAP gene.
Periostin is a protein that in humans is encoded by the POSTN gene. Periostin functions as a ligand for alpha-V/beta-3 and alpha-V/beta-5 integrins to support adhesion and migration of epithelial cells.
Monocarboxylate transporter 1 is a ubiquitous protein that in humans is encoded by the SLC16A1 gene. It is a proton coupled monocarboxylate transporter.
In medicine, desmoplasia is the growth of fibrous or connective tissue. It is also called a desmoplastic reaction to emphasize that it is secondary to an insult. Desmoplasia may occur around a neoplasm, causing dense fibrosis around the tumor, or scar tissue (adhesions) within the abdomen after abdominal surgery.
Pancreatic stellate cells (PaSCs) are classified as myofibroblast-like cells that are located in exocrine regions of the pancreas. PaSCs are mediated by paracrine and autocrine stimuli and share similarities with the hepatic stellate cell. Pancreatic stellate cell activation and expression of matrix molecules constitute the complex process that induces pancreatic fibrosis. Synthesis, deposition, maturation and remodelling of the fibrous connective tissue can be protective, however when persistent it impedes regular pancreatic function.
David Arthur Tuveson is an American cancer biologist and is currently Roy J. Zuckerberg Professor of Cancer Research as well as The Cancer Center Director at Cold Spring Harbor Laboratory. Dr. Tuveson is also the Chief Scientist for the Lustgarten Foundation for Pancreatic Cancer Research. He is known for developing some of the first mouse models of pancreatic cancer and more recently, for his work developing pancreatic cancer organoids.
Hedgehog pathway inhibitors, also sometimes called hedgehog inhibitors, are small molecules that inhibit the activity of a component of the Hedgehog signaling pathway. Due to the role of aberrant Hedgehog signaling in tumor progression and cancer stem cell maintenance across cancer types, inhibition of the Hedgehog signaling pathway can be a useful strategy for restricting tumor growth and for preventing the recurrence of the disease post-surgery, post-radiotherapy, or post-chemotherapy. Thus, Hedgehog pathway inhibitors are an important class of anti-cancer drugs. At least three Hedgehog pathway inhibitors have been approved by the Food and Drug Administration (FDA) for cancer treatment. These include vismodegib and sonidegib, both inhibitors of Smoothened (SMO), which are being used for the treatment of basal cell carcinoma. Arsenic trioxide, an inhibitor of GLI transcription factors, is being used for the treatment of acute promyelocytic leukemia. In addition, multiple other Hedgehog pathway inhibitors are in different phases of clinical trials.
Nita Ahuja is a surgeon and the Chair of the Department of Surgery at Yale School of Medicine and Surgeon-in-Chief of Surgery at Yale New Haven Hospital. She is the first woman ever to serve as Chair of Surgery in Yale in its >200 year history. Before taking this position she was the first woman ever to be the Chief of Surgical Oncology at Johns Hopkins Hospital, Baltimore, USA. Ahuja researches in the field of epigenetics and is a passionate advocate of clinician scientist. She also served as the director of Sarcoma and peritoneal surface malignancy program. She is a surgeon-scientist and her research has been cited more than 11,000 times in scientific literature.
Minoti Vivek Apte is an Indian-born Australian pancreatology researcher and is the Director of Pancreatic Research Group at the University of South Wales and Ingham Institute for Applied Medical Research in Liverpool, New South Wales, Australia. She is also a classical Indian dancer and choreographer.
Apte is notable for her many achievements in the field of pancreatic disease research, including becoming the first in the world to successfully isolate pancreatic stellate cells (PSCs), the cells associated with pancreatic fibrogenesis. The effectiveness of this isolation method allowed her team to prove that PSCs’ close communication with cancerous cells contributes to the aggressiveness of pancreatic cancer, a major discovery that led the government of New South Wales to award her The Premier's Award for Woman of the Year in 2015.
Jean Sylvia Marshall, born in Birmingham, England, is a Canadian immunologist and acting Professor and Head of the Department of Microbiology & Immunology at Dalhousie University in Halifax, Nova Scotia, Canada. Marshall's work has investigated how mast cells are involved in the early immune response to infection and antigen. She is best known for her discovery of the previously unknown degranulation-independent immunoregulatory roles of mast cells in infection and allergy and their ability to mobilize dendritic cells.
Carol Shoshkes Reiss, an American viral immunologist, has been professor in New York University's department of biology since 1991. Her research focused on the dynamic contest between the mouse immune system and virus replication during infection of the central nervous system.
