Despite significant homology between IRS-1 and IRS-2, recent studies have revealed distinct functions for these adaptor proteins in regulating breast cancer progression. Thus far, most of the studies on breast cancer have focused upon IRS-1, the biological pattern of IRS-2 is limited. We demonstrated that depletion of endogenous IRS-2 by antisense strategies impaired cell proliferation after se...
The period immediately after exercise is characterized by enhanced insulin action in skeletal muscle, and on the molecular level, by a marked increase in insulin-stimulated, phosphotyrosine-associated phosphatidylinositol (PI) 3-kinase activity. Because the increase in PI 3-kinase activity cannot be explained by increased insulin receptor substrate (IRS)-1 signaling, the present study examined ...
In this study, we analyzed vitamin D receptor (VDR) expression and survival in a breast cancer patient cohort of 82 breast cancer patients. Immunohistochemical analysis was possible in 91.5% of the patients (75/82). Staining was evaluated using the semi-quantitative assay according to Remmele and Stegner (immunoreactivity score [IRS]). IRS 0-1 was negative/very low, IRS 2-4 was moderate to high...
Incident Reporting Systems (IRS) are and will continue to be an important influence on improving patient safety. They can provide valuable insights into how and why patients can be harmed at the organizational level. However, they are not the panacea that many believe them to be. They have several limitations that should be considered. Most of these limitations stem from inherent biases of volu...
Insulin receptor substrate-2 (IRS-2) belongs to the IRS family of adaptor proteins that function as signaling intermediates for growth factor, cytokine, and integrin receptors, many of which have been implicated in cancer. Although the IRS proteins share significant homology, distinct functions have been attributed to each family member in both normal and tumor cells. In cancer, IRS-2 is positi...
The complexity status of the maximum stable set problem in the class of P5-free graphs is unknown. In this paper, we 3rst propose a characterization of all connected P5-free augmenting graphs. We then use this characterization to detect families of subclasses of P5-free graphs where the maximum stable set problem has a polynomial time solution. These families extend several previously studied c...
IRS-1 is a major substrate for insulin receptor tyrosine kinase. It is reported that intracellular translocation of serine-phosphorylated IRS-1 from low density microsome (LDM) fraction to cytosol attenuates its ability to transmit insulin signaling to the downstream molecules. In this study, we examined which insulin signal and action were affected by translocation of IRS-1 in 3T3-L1 adipocyte...
Our special fuzzy classifier operates on the set of eight features extracted from the 3x3 neighborhood of each pixel. These features are the magnitudes of differences between that pixel and the eight neighboring pixels. They are input into the fuzzy classifier inputs that connect to two fuzzy set membership functions that represent “white background” or “black edge.” The paradigm is simple, com...
