Advanced Science, EarlyView.Lactylation, linked to glycolysis, is poorly understood in regulation. It is found that LDHA is lactylated at Lys81/Lys318 by AARS1, boosting its activity and cellular lactylation via positive feedback in LUAD. Lactylation regulates NHEJ‐related proteins; their delactylation impairs NHEJ and increases cisplatin sensitivity, offering anticancer insights.

Comparison of three radio-frequency discharge modes on the treatment of breast cancer cells in vitro [PDF]
, 2019 Non-thermal plasmas (NTPs) are known for their ability to induce thermal-free cytotoxic effects on cancer cells. However, as the variety of NTP devices increases, comparison of their cytotoxic effect becomes increasingly essential.

Advanced Science, EarlyView.Glutamine deprivation triggers ACSL5 upregulation in tumor cells, sustaining their viability via dual metabolic rewiring programs. ACSL5 enhances glycolysis by relieving p53's inhibition of PGAM1 while also sustaining mitochondrial respiration and TCA cycle flux through promoting IDH2 dimerization.

Automated comet assay analysis [PDF]
Cytometry, 1999 Recently the "comet assay" or "single-cell gel electrophoresis assay" has been established as a sensitive method for the detection of DNA damage and repair. Most of the software now available to quantify various parameters for DNA damage requires the interaction of a human observer. In this report, we describe an automated analysis system that is based
