Chemical p38 MAP Kinase Inhibition Constrains Tissue Inflammation and Improves Antibiotic Activity in Mycobacterium tuberculosis-Infected Mice

Investigators showed that in vivo treatment of Mycobacterium tuberculosis-infected C57BL/6 mice with doramapimod, a p38 MAP-kinase inhibitor, resulted in reduced inflammation, granuloma formation and lung pathology.

DRP1 Promotes Lactate Utilization in KRAS‐Mutant Non‐Small Cell Lung Cancer Cells

Scientists developed a lactate‐dependent cell proliferation assay and found that dynamin‐related protein (DRP1), which was highly expressed in KRAS‐mutant non‐small cell lung cancer (NSCLC), was required for tumor cells to proliferate and uses lactate as fuel, demonstrating the critical role of DRP1 in the metabolic reprogramming of NSCLC.

ERK/MAPK Signaling Is Essential for Intestinal Development through Wnt Pathway Modulation

Scientists found that deletion of Erk1/2 in intestinal epithelial cells at embryonic stages resulted in an unexpected increase in cell proliferation and migration, expansion of intestinal stem cells and formation of polyp-like structures, leading to postnatal death.

GINS2 Promotes EMT in Pancreatic Cancer via Specifically Stimulating ERK/MAPK Signaling

Investigators found that overexpression of Go-Ichi-Ni-San 2 (GINS2) contributed to advanced clinical stage of pancreatic cancer patient and promoted epithelial–mesenchymal-transition in vitro and in vivo via specifically activating ERK/MAPK signal pathway.

Unique Targeting of Androgen‐Dependent and ‐Independent AR Signaling in Prostate Cancer to Overcome Androgen Resistance

The authors investigated the ability of novel anti‐cancer agents, Dp44mT and DpC, to overcome androgen resistance. The effect of Dp44mT and DpC on androgen‐dependent and independent androgen receptor signaling was assessed in androgen‐dependent and ‐independent prostate cancer cells using 2D‐ and 3D‐tissue culture.

Cellular Senescence Promotes Skin Carcinogenesis through p38MAPK and p44/p42MAPK Signaling

Scientists showed for the first time that senescent cells were tumor promoters, not tumor initiators, and that they stimulated skin carcinogenesis by elevating p38 MAPK and MAPK/ERK signaling.
