One of major complications of ischemic heart disease is myocardial infarction, which develops as a result of thrombosis at the site of ruptured atherosclerotic plaque. Platelets activation and aggregation are the key events of this process. The efficiency of aspirin and/or clopidogrel use is limited by residual platelet reactivity what indicates the need to explore its mechanisms. This review covers intracellular signaling systems involved in realization of effects of the main platelet agonists in order to specify new molecules for the target therapy in case of aspirin resistance.

Biology uses many signaling mechanisms. Among them, calcium and membrane potential are two prominent mediators for cellular signaling. TRPM4 and TRPM5, two calcium-activated monovalent cation-conducting ion channels, offer a direct linkage between these two signals.

The Munc13/UNC-13 family protein Ync13 is essential for septum integrity and cytokinesis in fission yeast. To further explore the mechanism of Ync13 functions, spontaneous suppressors of mutants, which can suppress the colony-formation defects and lysis phenotype of mutant cells, are isolated and characterized. One of the suppressor mutants, -, shows defects in the cytokinetic contractile ring constriction, septation, and daughter-cell separation, similar to mutant.

Compared to fluorescence, second harmonic generation (SHG) has recently emerged as an excellent signal for imaging probes due to its unmatched advantages in terms of no photobleaching, no phototoxicity, no signal saturation, as well as the superior imaging accuracy with excellent avoidance of background noise. Existing SHG probes are constructed from heavy metals and are cellular exogenous, presenting with high cytotoxicity, difficult cellular uptake, and the limitation of non-heritability. We, therefore, initially propose an innovative gene-encoded bioprotein SHG probe derived from Autographa californica nuclear polyhedrosis virus (AcMNPV) polyhedrin.

To investigate the effect of icariin (ICA) on hepatocellular carcinoma (HCC) and its autophagy/apoptosis mechanism in HCC. The anti-HCC mechanism of ICA was investigated using HCC cells treated with 20 µmol/L ICA. Cell viability and proliferation were assessed using CCK-8 and colony formation assays, respectively, while TUNEL staining evaluated anti-apoptotic effects.

Mutations that increase LRRK2 kinase activity have been linked to Parkinson's disease and Crohn's disease. LRRK2 is also activated by lysosome damage. However, the endogenous cellular mechanisms that control LRRK2 kinase activity are not well understood.
