Oncogenic potential of truncated-Gli3 via the Gsk3β/Gli3/AR-V7 axis in castration-resistant prostate cancer.

The functional activation of the androgen receptor (AR) and its interplay with the aberrant Hh/Gli cascade are pivotal in the progression of castration-resistant prostate cancer (CRPC) and resistance to AR-targeted therapies. Our study unveiled a novel role of the truncated form of Gli (t-Gli3) in advancing CRPC. Investigation into Gli3 regulation revealed a Smo-independent mechanism for its activation.

Nuclear GTPSCS functions as a lactyl-CoA synthetase to promote histone lactylation and gliomagenesis.

Histone lysine lactylation is a physiologically and pathologically relevant epigenetic pathway that can be stimulated by the Warburg effect-associated L-lactate. Nevertheless, the mechanism by which cells use L-lactate to generate lactyl-coenzyme A (CoA) and how this process is regulated remains unknown. Here, we report the identification of guanosine triphosphate (GTP)-specific SCS (GTPSCS) as a lactyl-CoA synthetase in the nucleus.

A Method for Efficient De-identification of DICOM Metadata and Burned-in Pixel Text.

De-identification of DICOM images is an essential component of medical image research. While many established methods exist for the safe removal of protected health information (PHI) in DICOM metadata, approaches for the removal of PHI "burned-in" to image pixel data are typically manual, and automated high-throughput approaches are not well validated. Emerging optical character recognition (OCR) models can potentially detect and remove PHI-bearing text from medical images but are very time-consuming to run on the high volume of images found in typical research studies.
