Membrane closure in stress induced-autophagosome formation
Eiji Morita1
Autophagy (macroautophagy) is a bulk degradation system that sequesters cytoplasmic components by generating double-layered isolation membranes and delivering these isolated contents to the lysosomes [cite]10.1146/annurev-cellbio-092910-154005[/cite]. Though this pathway was originally
Novel role of the SIRT4-OPA1 axis in mitochondrial quality control
Alexander Lang1 and Roland P. Piekorz1
Aging is defined by various molecular and cellular hallmarks, among them stem cell exhaustion, genomic instability, altered proteostasis, cellular senescence, and mitochondrial dysfunction [cite]10.1016/j.cell.2013.05.039[/cite]. Mitochondrial defects are considered major drivers
Tumor suppressive Ca2+ signaling is driven by IP3 receptor fitness
Geert Bultynck1 and Michelangelo Campanella2,3
Intracellular Ca2+ signals critically control a plethora of cellular functions, of which many impact cellular death and/or survival, processes often dysregulated in cancer [cite]10.1038/nrc.2017.18[/cite]. In healthy cells, Ca2+ signaling is
The long non-coding RNA H19 – a new player in hepatocellular carcinoma
Maximilian A. Ardelt1 and Johanna Pachmayr2
Hepatocellular carcinoma (HCC) is among the most prevalent and lethal cancers worldwide [cite]10.3322/caac.20107[/cite]. Incidence is increasing and due to its high chemoresistance, the therapeutic options are limited and HCC has
