Hydroxysafflor yellow A inhibited lipopolysaccharide-induced non-small cell lung cancer cell proliferation, migration, and invasion by suppressing the PI3K/AKT/mTOR and ERK/MAPK signaling pathways

397 views | May 18 2019

HYSA suppressed LPS-mediated proliferation, migration, invasion, and EMT in A549 and H1299 cells by inhibiting the PI3K/Akt/mTOR and ERK/MAPK signaling pathways, indicating that HYSA may be a potential candidate to treat inflammation-mediated NSCLC. [Read the Full Post]

Inhibition of apoptosis by caspase inhibitor Z-VAD-FMK improves cryotolerance of in vitro derived bovine embryos

891 views | May 17 2019

Pero ME et al. found that the addition of 20 μM Z-VAD-FMK during vitrification/warming and post-warming culture partially inhibits cryopreservation-induced apoptosis by reducing the level of active caspase 3, suggesting a potential use as an additive to ameliorate the efficiency of embryo cryopreservation in cattle, critical for a further diffusion of IVEP technology in the field.
