Phagocytosis is an essential mechanism for clearance of pathogens, dying cells, and other unwanted debris in order to maintain tissue health in the body. Macrophages execute this process in the peripheral immune system, but in the brain microglia act as resident macrophages to accomplish this function. In the peripheral immune...
Little is known about the transcriptional events underlying megakaryocytic (Mk) differentiation from hematopoietic stem cells. We sought to identify genes and pathways not previously associated with megakaryopoiesis and to evaluate the CHRF-288-11 (CHRF) megakaryoblastic cell line as a model system for investigating megakaryopoiesis.
Using DNA microarrays, Q-RT-PCR, and protein-level assays,...
Breast cancer cells acquire many genetic alterations in apoptotic signaling pathways rendering them resistant to apoptosis. Human Epidermal growth factor Receptor-2 (HER-2/ErbB2/neu) is amplified or overexpressed in approximately 30% of breast and ovarian tumors and correlates with poor prognosis. Although HER-2 is an orphan receptor, it forms potent signaling heterodimers...
