Sungmi Song et al.
Cell death & disease, 11(2), 109-109 (2020-02-09)
By comparing imatinib-sensitive and -resistant chronic myeloid leukemia (CML) cell models, we investigated the molecular mechanisms by which tetrahydrobenzimidazole derivative TMQ0153 triggered caspase-dependent apoptosis at low concentrations accompanied by loss of mitochondrial membrane potential (MMP) and increase of cytosolic free
Sulin Zhang et al.
Autophagy, 16(4), 735-749 (2019-06-19)
The non-receptor tyrosine kinase SRC is a key mediator of cellular protumorigenic signals. SRC is aberrantly over-expressed and activated in more than 80% of colorectal cancer (CRC) patients, therefore regulation of its stability and activity is essential. Here, we report
Fibroblast mTOR/PPAR$ gamma/ HGF axis protects against tubular cell death and acute kidney injury
Gui Y, et al
Cell Death and Differentiation, 26(12), 2774-2789 (2019)
Sangam Rajak et al.
Molecular metabolism, 53, 101286-101286 (2021-07-06)
Crinophagy is a secretory granule-specific autophagic process that regulates hormone content and secretion in endocrine cells. However, despite being one of the earliest described autophagic processes, its mechanism of action and regulation in mammalian cells remains unclear. Here, we examined
Guang Lu et al.
Autophagy, 15(11), 1917-1934 (2019-03-23)
Macroautophagy/autophagy is a cellular process in which cytosolic contents are degraded by lysosome in response to various stress conditions. Apart from its role in the maintenance of cellular homeostasis, autophagy also involves in regulation of cell cycle progression under nutrient-deprivation
Chen Liao et al.
FASEB journal : official publication of the Federation of American Societies for Experimental Biology, 34(6), 8283-8295 (2020-04-24)
Ribosomal DNA (rDNA) transcription is a limiting step in ribosome biogenesis, crucial for protein synthesis and cell growth-especially at the early stages of embryonic development-and is regulated in a mammalian target of rapamycin (mTOR)-dependent manner. Our previous report demonstrated that
Piero Dalle Pezze et al.
Autophagy, 17(5), 1131-1141 (2020-04-23)
During macroautophagy/autophagy, the ULK complex nucleates autophagic precursors, which give rise to autophagosomes. We analyzed, by live imaging and mathematical modeling, the translocation of ATG13 (part of the ULK complex) to the autophagic puncta in starvation-induced autophagy and ivermectin-induced mitophagy.
Transient inhibition of rDNA transcription in donor cells improves ribosome biogenesis and preimplantation development of embryos derived from somatic cell nuclear transfer
Liao C, et al.
Faseb Journal, 26(12), 2774-2789 (2020)
Maria Catalina Gomez-Puerto et al.
The Journal of pathology, 249(3), 356-367 (2019-07-02)
Pulmonary arterial hypertension (PAH) is characterised by an increase in mean pulmonary arterial pressure which almost invariably leads to right heart failure and premature death. More than 70% of familial PAH and 20% of idiopathic PAH patients carry heterozygous mutations
TOR signaling downregulation increases resistance to the cereal killer Fusarium graminearum
Aznar N, et al.
Plant signaling & behavior, 13(2), e1414120-e1414120 (2018)
Maria Zachari et al.
Developmental cell, 50(5), 627-643 (2019-07-30)
The dynamics and coordination between autophagy machinery and selective receptors during mitophagy are unknown. Also unknown is whether mitophagy depends on pre-existing membranes or is triggered on the surface of damaged mitochondria. Using a ubiquitin-dependent mitophagy inducer, the lactone ivermectin
Min Liu et al.
Biochemical and biophysical research communications, 463(3), 255-261 (2015-05-24)
Activation of quiescent hepatic stellate cells (HSCs) is the central event of liver fibrosis. The translational machinery is an optimized molecular network that affects cellular homoeostasis and diseases, whereas the role of protein translation in HSCs activation and liver fibrosis
Atsushi Yamamoto et al.
Biology of reproduction, 91(1), 7-7 (2014-05-24)
Autophagy is a dynamically regulated intracellular degradation system that is important for cellular processes such as amino acid production during starvation and intracellular quality control. Previously, we reported that autophagy is suppressed in oocytes but is rapidly up-regulated after fertilization.
Huiwang Zhan et al.
Developmental cell, 54(5), 608-623 (2020-09-03)
The Ras/PI3K/extracellular signal-regulated kinases (ERK) signaling network plays fundamental roles in cell growth, survival, and migration and is frequently activated in cancer. Here, we show that the activities of the signaling network propagate as coordinated waves, biased by growth factor
Néstor R Aznar et al.
Plant signaling & behavior, 13(2), e1414120-e1414120 (2017-12-12)
TOR is the master regulator of growth and development that senses energy availability. Biotic stress perturbs metabolic and energy homeostasis, making TOR a good candidate to participate in the plant response. Fusarium graminearum (Fusarium) produces important losses in many crops
Hyun-Kyoung Kim et al.
Autophagy, 17(3), 761-778 (2020-03-14)
Lysosomal Ca2+ contributes to macroautophagy/autophagy, an intracellular process for the degradation of cytoplasmic material and organelles in the lysosomes to protect cells against stress responses. TMBIM6 (transmembrane BAX inhibitor motif containing 6) is a Ca2+ channel-like protein known to regulate
