Fluorescent stain for nucleic acids. Cell membrane integrity excludes propidium iodide from staining viable and apoptotic cells. Propidium iodide may be used in flow cytometry to evaluate cell viability when used with other dyes that stain viable cells or cells that are early in the apoptosis process.

Precise glycosylation plays a crucial and distinctive role in thymic T cell development. The core fucosylation is dramatically up-regulated at the transition from CD4-CD8- (DN) to CD4+CD8+ (DP) in the thymic development. Ablation of core fucosylation in T cells did...

To cellular systems, nanoparticles are considered as foreign particles. Upon particles and cells contact, innate immune system responds by activating the inflammatory pathway. However, excessive inflammation had been linked to various diseases ranging from allergic responses to cancer. Common nanoparticles...

Solid tumors contain regions of chronic and cyclic hypoxia. Chronic hypoxia can downregulate RAD51 and sensitize cells to PARP inhibition. Herein, we show that RAD51 expression, cell survival and toxicity to PARP inhibition is not affected under cyclic hypoxic conditions....

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.
