Summary: The study demonstrates that Cardamonin inhibits proliferation, migration, and invasion of osteosarcoma cells, inducing cell cycle arrest. It has minimal effects on normal cells and represses tumor growth in a xenograft mouse model. Mechanistically, Cardamonin activates the P38 and JNK MAPK signaling pathway to promote apoptosis in osteosarcoma cells.

Summary: The study demonstrates that 6-gingerol can protect against pressure overload-induced cardiac remodeling in in vivo models by improving cardiac function and alleviating hypertrophy, fibrosis, inflammation, and dysfunction. In vitro experiments showed that 6-gingerol can block cardiomyocyte hypertrophy and cardiac fibroblast activation in response to specific stimuli.

Summary: This study investigates the pivotal role of Nuclear factor-erythroid 2-related factor 2 (NRF2) in the activation of DNA damage repair in lung cancer cells after x-rays exposure. The study shows that NRF2 knockdown disrupts damaged DNA repair and homologous recombination, and NRF2 activation mediates DNA damage response via the MAPK pathway. These findings suggest that NRF2 plays a critical role in the development of radioresistance, which is of great significance for the development of radiotherapies.

Summary: The study aimed to investigate the activation of microglia and p38 MAPK expression in the lumbar spinal cord after thoracic SCI in rats, as well as the therapeutic effect of ROCK inhibitor ripasudil in SCI rats. The results showed that ROCK activation in microglia may play a key role in p38 MAPK activation, which is crucial in the development of neuropathic pain after SCI. Inhibition of ROCK signaling may be a novel treatment approach for neuropathic pain after SCI.

Summary: The sonic hedgehog (SHH) signaling pathway plays a crucial role in synovial inflammation and joint destruction in rheumatoid arthritis (RA) by promoting abnormal behavior of activated fibroblast-like synoviocytes (FLS) in a p38-dependent manner. Inhibition of the SHH-p38 MAPK signaling pathway may be a potential target for the treatment of RA.

Summary: Hypoxia activates the Notch4-ERK/JNK/P38 MAPK signaling pathway to promote the proliferation, migration, and anti-apoptotic effects of LUAD cells. Notch4 plays a key role in the growth and metastasis of LUAD. Inhibitors of ERK, JNK, and P38 can partially reverse the effects of Notch4.

Summary: ATF6a is an endoplasmic reticulum protein involved in unfolded protein response in mammals. In differentiating mouse C2C12 myoblasts, only the ATF6a pathway of UPR is activated. Activation of ATF6a depends on p38 MAPK and its inhibition impairs myotube formation and trafficking of ATF6a.

Summary: MK2 plays a significant role in pulmonary hypertension, and its inhibition may be a novel target for PH treatment. Inhibition of MK2 alleviated right ventricle pressure and hypertrophy in PH rats, improved cardiac function, reversed pulmonary vascular remodeling, and enhanced pulmonary vascular relaxation.

Summary: This study investigated the protective effects and mechanisms of human placenta derived mesenchymal stem cells (hPMSCs) transplantation in a rat model of hypoxic-ischemic encephalopathy (HIE). The results showed that hPMSCs transplantation reduced apoptosis and improved long-term neurological prognosis. Furthermore, the downregulation of Sema 3A/NRP-1 expression and activation of the PI3K/Akt/mTOR signaling pathway played a key role in the protective effects of hPMSCs.

Summary: This study evaluated electrophysiological discrimination of parametric somatosensory stimuli in healthy young adults to understand how the brain processes the duration of tactile information. The results showed that participants did not electrophysiologically discriminate between 100 and 115 ms, but they exhibited distinct electrophysiological responses when the deviant stimuli were 130, 145, and 160 ms. These findings contribute to a better understanding of tactile sensitivity in different clinical conditions.

Summary: The basolateral amygdaloid complex (BLA) is closely involved in the formation of emotional memories, including both aversive memory and contextual fear memory. Acute sleep deprivation (SD) disrupts the acquisition of tone-associated fear memory in juvenile rats, but has no significant effect on contextual fear memory. Slow network oscillation in the amygdala contributes to the formation of amygdala-dependent fear memory in relation to sleep.

Summary: GSDME plays a crucial role in the pathogenesis of Alzheimer's disease by regulating the switch from apoptosis to pyroptosis and participating in neuroinflammatory response. Knockdown of GSDME has been shown to improve cognitive impairments, indicating that GSDME could be a therapeutic target for Alzheimer's disease.
