Decreased anchorage- dependent/independent cell growth and initiation of cell death under low growth factor and estrogen conditions are observed in MCF-7 cells with down-regulated IRS-1. [ 49 ] mir126 is underexpressed in breast cancer cells. mir126 targets IRS-1 at transcriptional level and inhibits transition from G1/G0 phase to S phase ...

Insulin receptor substrate 2 is a protein that ...
The insulin receptor (IR) is a transmembrane receptor that is activated by insulin, IGF-I, IGF-II and belongs to the large class of receptor tyrosine kinase. [5] Metabolically, the insulin receptor plays a key role in the regulation of glucose homeostasis; a functional process that under degenerate conditions may result in a range of clinical manifestations including diabetes and cancer.
A cell wall is a structural layer that surrounds some cell types, found immediately outside the cell membrane.It can be tough, flexible, and sometimes rigid. Primarily, it provides the cell with structural support, shape, protection, and functions as a selective barrier. [1]
The bacterial cell wall differs from that of all other organisms by the presence of peptidoglycan (poly-N-acetylglucosamine and N-acetylmuramic acid), which is located immediately outside of the cytoplasmic membrane. Peptidoglycan is responsible for the rigidity of the bacterial cell wall and for the determination of cell shape. It is ...
Its primary function is to give the cell its shape and mechanical resistance to deformation, and through association with extracellular connective tissue and other cells it stabilizes entire tissues. [ 4 ] [ 5 ] The cytoskeleton can also contract, thereby deforming the cell and the cell's environment and allowing cells to migrate . [ 6 ]
In both cases, F-actin is enriched around the cell periphery. Scale bar: 10 micrometers. The cell cortex, also known as the actin cortex, cortical cytoskeleton or actomyosin cortex, is a specialized layer of cytoplasmic proteins on the inner face of the cell membrane. It functions as a modulator of membrane behavior and cell surface properties.
Beta cells (β-cells) are specialized endocrine cells located within the pancreatic islets of Langerhans responsible for the production and release of insulin and amylin. [1] Constituting ~50–70% of cells in human islets, beta cells play a vital role in maintaining blood glucose levels. [ 2 ]
