EGFR INHIBITORS AGAINST THE CANCERS

4817 | Sep 12 2012

INHIBITION OF EGFR: Among those few cascades which play an important role in the functioning of cells, epidermal growth factor receptor or EGFR pathway is one that has a vital role in growth, survival and proliferation of cells. The importance of this cascade can only be observed and understood in case of development of tumors and fatal diseases related to the uncontrolled cell growth caused by the improper regulation of EGFR signaling pathway. Over or mutated expression of the EGFR is associated with different types of cancers like colon, lung and breast cancers and with multiform glioblastoma, anal and epithelial cancers. Therefore the treatment of these cancers by using the phenomenon of EGFR inhibition is found to be an attractive approach that led to magnify the importance of Erbb1 inhibitor. These inhibitors along with their use in clinical processes, are also concerned with the survival of patients and different EGFR antagonists and agonists are also in use for the revelation of various other cascades and the effects of EGFR pathway on them. EGFR inhibitors can be obtained from any relevant supplier at a very normal cost. [Read the Full Post]

GEFITINIB – REFGULATING EGFR in CANCER

3492 | Mar 19 2012

Introduction: The HER (EGFR) pathway and Gefitinib Protein kinases have been established in recent years as prime targets for selective inhibition in many disorders involving cell proliferation or cell migration. The extent of the protein kinase system is very large with hundreds of different proteins interacting together to send multitude of signals to nuclei determining growth, death, transcription or response to any form damage or stress. To enable understanding of the mechanism of action for all these proteins they have been classified under pathways which are directly related. One of these pathways that is significant in its effects is the HER pathway, originally known as the EGFR pathway in relation to the epithelial growth factor. However, more proteins related to EGFR were recognized (ErRB 2-4) and the HER family was born. The location of this series of proteins is too span across the cell membrane from the extracellular region (head) into the cytosole (tail). Attachment of ligands to the extracellular sites cause structural changes to the protein which expose tyrosine kinase binding domains in the section of the protein located in the cytosole.

ERLOTINIB – A ONE STOP SHOP

3312 | Mar 19 2012

Introduction: The HER (EGFR) pathway and Erlotinib Extracellular and intercellular signaling is a major process in the regulation of the life and death of cells within in any tissue matrix. One of the most well known and significant of these signaling steams is the HER protein family pathway consisting of four distinct receptors. Originally this was solely recognized as HER1 receptor called, due to its ligand association and since it was primarily found in epithelial cells, the “epithelial growth factor receptor”. Abbreviated to the acronym EGFR this receptor has since been found to have a family of 3 other closely related protein receptors, HER 2-4. Unfortunately these were known as ErB2-4 before the relationship with EGFR was determined, since then the entire family has been renamed to the HER family. These receptors consist of an extracellular section (head) with a Trans-membrane section and a cytosolic section (tail). Ligands binding to the extracellular domains initiate a dimerization between receptors which in turn induce conformational changes. [Read the Full Post]

EGFR INHIBITORS VERSUS CANCER

3389 | Mar 20 2012

Introduction: The HER family of proteins Recently collated and renamed as a single family of homologous series of proteins the HER family represents a major group of cellular membrane signal transmitters. Confusingly in literature the new naming system is inconsistently followed and the four HER receptors are often referred to as EGFR (HER1; ErRB1), ErRB2 (HER2), ErRB3 (HER3) and ErRB4 (HER4). These receptors have a very specific mode of action in that extracellular ligands can bind to the surface receptor domains on the cell membrane. Binding to any one of four different versions the ligand can stimulate a number of possible responses. Upon binding, the complex formed will alter conformationally and dimerize with another HER receptor increasing the number of permutations possible in the signaling process. The Dimerization initiates changes in the conformational state of the protein that induces the intercellular segment of the protein to reveal binding domains previously hidden. The protein will auto-phosphorylate activating it to receiving intercellular protein binding which starts the signaling process with the cell. The number of pathways that can be activated in different ways is large leading to contradictory responses. [Read the Full Post]

CP-690550: THE CURE FOR ARTHRITIS

6845 | Mar 20 2012

Introduction: JAK and its role in signaling pathways The protein kinase family plays an essential role in the government of the growth or death properties of mammalian tissues. These proteins form an interrelated, redundant system that is capable of selectively initiating the growth of certain cell types in response to the needs of the host system. To do this the protein kinase super family is subdivided into a series of related protein kinases which make up a signaling pathway, traveling from the extracellular matrix into the cell nucleus. The Janus kinase pathway is one which is activated in response to the action of cytokines on the cytokine transmembrane receptors. Since these receptors have no kinase ability themselves they are total dependant on the Janus kinases (JAK) for activity. [Read the Full Post]

INCB18424 – JACKING THE JAK2

7437 | Mar 20 2012

Introduction: JAK2 in relation to metabolic blood disorders The transmission of signals from extracellular factors through the cell membrane to effect actions within the cell cytosole and nucleus is conducted along pathways of protein to protein interactions. Many metabolic disorders have been associated with aberrations in these pathways causing a variety of destructive cellular actions. Many of these diseases possess no known cure and in response research has focused on the mechanisms behind the progression of these diseases. One area that has received a lot of attention is the possibility that the natural immune function can be detrimental to healthy growth patterns if over stimulated by mutations in the genetic information of individuals. A key series of proteins in the immune response is the Janus kinases (JAK), a series of four distinct but domain related kinases located in the cellular cytosole. These kinases form a distinct link between extracellular immune function ligands and a direct regulation of transcription of genetic information. However, a mutation of the JAK2 isoform has been associated with degenerative effects such as myeloproliferative neoplasms, thrombocythemia, polycythemia vera and psoriasis. [Read the Full Post]

TASOCITINIB: THE REVOLUTION IN ARTHRITIS MANAGEMENT

7223 | Mar 18 2012

Introduction: Inhibition of the JAK pathway The protein kinases are a super family of protein that govern the control of cellular growth, creation of vascular structure and many other processes the control the way in which cells and tissue regenerate. In is estimated that 30% of all cellular regulation is governed by protein kinases. Protein kinases are subdivided into 7 different classifications of which one is the tyrosine kinases. These kinases operate by phosphorylation of a tyrosine amino acid residue transferring a signal down a cascade of protein to regulate cellular processes. A further subdivision of the tyrosine kinases can be made into receptor based kinases and non receptor based kinases. The Janus kinases (JAK) are a sub family of the receptor based tyrosine kinases. Signals from the JAK regulate the cytokines, the GM-CSF family and the GP130 receptor family. JAK kinases exist in the 4 distinct isoforms with twinned phosphorylation domains. Inhibitors of the JAK kinases have been demonstrated to have a positive effect on cancerous cells both in vivo and in vitro. [Read the Full Post]

RUXOLITINIB: THE JACK FOR JAK INHIBITION

7527 | Mar 13 2012

Ruxolitinib: Inhibition of the Janus Kinases The janus kinases are a sub family of the protein kinases and are refer to as non receptor tyrosine kinases. Signals from the Janus kinases regulate several different types of proteins such as the cytokine receptor family (interferon), the GM-CSF family and the GP130 receptor family. The JAK kinases occur in four isoforms, with two matching phosphorylation domains, one for activity one for regulation. JAK2 in been shown to be mutated in several conditions including thrombocthemia and myeloprliferation disorders. In relation to haematological maliganacies the JAK2 mutation have been shown to essential for tumor growth and proliferation. Inhibiting the JAK2 kinase offers a potential mechanism for chemotherapeutic action. Ruxolitinib is a small, molecule inhibitor that has been established to inhibit the Janus kinases; early clinic work established that Ruxolitinib has sufficient anti-tumor activity to warrant further investigation.

EGFR INHIBITORS CONTROLLING TUMORIGENESIS

4274 | Mar 13 2012

Introduction: The EGFR’s role in the HER pathway A major pathway in the regulation of cell growth / death is the HER pathway, this pathway consists of four structurally related proteins primarily located in the cell membrane. The family members consist of HER1 (also known as EGFR), HER2 (also known as ErbB2), HER3 (also known as ErbB3) and HER4 (also known as ErbB4). These receptors consist of an extracellular head and an intracellular tail lying across the cell membrane. Ligands binding to the extracellular receptor induce conformational changes which reveal binding domains within the intracellular tail. Auto-phosphorylation of the tyrosine kinase domain is a result of the HER receptor forming dimers and depending on which of several different ligands induced the change the tail section attracts proteins to initiate signaling cascades to the nucleus. Ligands that trigger this signaling pathway consist of endothelial growth factor (EGF), transforming growth factor alpha (TGFα), beracellulin (BTC), epiregulin (EPR) and amphiregulin (AREG).
