Our results show the genetic mechanism through which cell selection mediates elimination of suboptimal but viable cells.
We reasoned that the pi-RISC, by virtue of the enormous sequence portfolio of piRNAs, might mediate elimination of a large variety of mRNAs in late stages of spermiogenesis.
Additionally, the growth medium for ZR-75-1 wasupplementeded with 1 nM β-estradiol (Sigma-Aldrich), and did not contain sodium pyruvate, which mediates elimination of H2O2 from the culture medium [ 21].
The binding of activated platelets to tumor cells has been shown to hinder natural killer cell mediated elimination of circulating tumor cells [ 21], and the destruction of circulating platelets with antiplatelet antibodies significantly reduces metastatic potential in several murine tumor models [ 22].
Honda, S. et al. Ulk1-mediated Atg5-independent macroautophagy mediates elimination of mitochondria from embryonic reticulocytes.
Certain immune cells such as neutrophils mediate elimination of foreign organisms such as bacteria and fungi with superoxide that is produced by NADPH oxidases located on the cell membrane [29].
Therefore, the downregulated miR-29 may regulate the T helper 1 (Th1) cell differentiation to secrete more IFN-gamma and mediate elimination of intracellular pathogens, but dysregulated T cell responses may also contribute to pathologic inflammation.
This indicates that, once ESCs have exited the ground state of pluripotency, Lif is less efficient at signaling and suggests that, although events downstream of Lif may be mediating the elimination of Bmpr1a− / − ESCs, Lif itself is not directly involved in cell competition.
The interaction of the adhesion molecule of the immunoglobulin family intercellular adhesion molecule 1 (ICAM-1) with its ligands such that the integrins LFA-1 and Mac-1 is crucial for the regulation of several physiological and pathophysiological processes like cell mediated-elimination of tumor or virus infected cells, cancer metastasis or inflammatory autoimmune processes.
Phagocytosis, the engulfment of particles, mediates the elimination of invading pathogens as well as the clearance of apoptotic cells.
