Integrins are transmembrane receptors composed of alpha and beta chains, where beta-integrins are mainly expressed in leukocytes. Leukocytes are white blood cells that act in the immune system to defend our body against foreign pathogens.

The root of Parkinson’s disease (PD) points to a poorly regulated electron transport chain leading to mitochondrial damage, where many proteins need to work cohesively to ensure proper function.  The two key players of this pathway are PINK1, also known as PTEN or PARK6, and Parkin, also known as PARK2 - where PINK1 acts as an upstream effector of Parkin to regulate mitochondrial dynamics.  Mitochondria must maintain a healthy equilibrium and do so by undergoing a series of fission and fusion event

Today in breast cancer research, scientists are focused on determining the cause, risk, diagnostic testing options and treatment of this devastating disease.  Of particular interest is identification of potential therapeutic targets that are known to contribute to the progression of breast cancer in order to develop treatments against these specific genes or proteins.  This article review summarizes research completed by AlHossiny et al regarding the role of Ly6E/K signaling and TGF-beta is the progression of cancer, immune escape and subs

The process of autophagy, or lysosome-mediated degradation of damaged proteins and organelles in the cytosol, is a vital cellular process that acts as a quality control mechanism for proteins and organelles. The misregulation of autophagy can lead to an imbalance of cellular homeostasis and the subsequent development of disease.  Therefore, the study of autophagy is at the forefront of neuroscience and cancer research, among others.

Eukaryotic translation initiation factor 4E binding protein 1, or 4EBP1, is an mRNA translational repressor protein that negatively regulates eukaryotic translation initiation factor 4E, or EIF4E.  EIF4E is a protein that forms a complex necessary to block the 5’ ends of mRNA with a 7-methyl-guanosine five-prime cap structure, which is important for normal translation of mRNA.  Specifically, the EIF4E complex recruits 40s ribosome subunits to scan mRNA in order to regulate protein synthesis.  When EIF4E is bound to 4EBP1, it is held in an

HIF-2 alpha, also known as hypoxia-inducible factor 2, endothelial PAS domain protein-1, and member of PAS superfamily 2 is part of the HIF family of proteins.  The HIF family is composed of HIF-1, HIF-2 and HIF-3, where HIF-2 is a dimeric protein that consists of an alpha and beta subunit.HIF-2 alphais activated in the presence of oxygen deprivation, or hypoxia, via prolyl hydroxylase-domain enzymes (PHD

c-Myc, a proto-oncogene, has documented involvement in cellular differentiation, cell growth, cell death and tumor formation.  Target genes of the Myc family include those that participate in cell survival, translation, transcription, metabolism and more.  On a more specific level, c-Myc is a transcription factor that can both activate and repress its target protein by way of DNA modifications.  This allows for the use of a c-Myc antibody in two manners; it can be used to monitor the actual c-Myc protein expression levels, or, it

The CiteAb Lifetime Achievement Award recognizes and promotes an individual who has made an outstanding contribution to the research antibody industry over a sustained period of time.

Immunohistochemistry (IHC) is a widely applied experimental method used to examine tissue antigen expression and behavior with the use of an antibody conjugated to a secondary tag for visualization.  IHC consists of a tissue preparation phase, an antibody-staining phase, and a result analysis phase - all of which may lead to skewed results if not properly performed.  One way to ensure that IHC staining results are in fact demonstrating protein behavior and not a side effect the experimental process is to use IHC controls within each expe

p53, the protein product of the tp53 gene, is one of the most widely studied tumor suppressor proteins in cancer research.  p53 is unique in that it demonstrates both tumor suppressive and tumor progressive properties depending on whether it is functional or mutated.  The most common mutation in the p53 protein that leads to lack of tumor suppression activity is a missense mutation, however frameshift or nonsense mutations are also common.  In fact, mutant p53 has exhibited dominant negative inhibition of the wild type version of the protein, demonstrating the fact that the p53 pat
