Summary: Studying stress-activated signaling is challenging due to induced adaptation and imposed selection pressure. By using an optogenetic system to express light-activated p38 alpha or its upstream activator MKK6, the functional roles of these kinases in dynamic signaling programs are clarified.

Summary: Gliomas are debilitating malignant brain tumors with limited response to therapies, driven by molecular abnormalities like mutations in regulatory networks. The MAPK pathway, particularly p38 MAPK activation, plays a crucial role in glioma cell invasion and metastasis, and is associated with tumor grade and chemotherapy resistance, underlining its potential as a therapeutic target.

Summary: A novel BRAF variant was found to be associated with hypospadias phenotype, leading to abnormal p38 MAPK signaling. Two additional variants in p38 MAPK signaling-related genes were also identified potentially associated with hypospadias.

Summary: This study investigates the important role of mitogen-activated protein kinase 6 (MAPK6) in high temperature bolting of lettuce. The researchers amplified the full-length coding sequence of the LsMAPK6 gene and analyzed its expression using real-time polymerase chain reaction. The results demonstrate that LsMAPK6 is mainly expressed in the stem, stem apex, and taproot, and its expression is significantly promoted by high temperatures.

Summary: The study demonstrates that overexpression of StMAPK11 can promote potato growth, physiological activities, and photosynthesis under drought conditions, indicating its crucial role in enhancing potato drought resistance. The up-regulation of StMAPK11 intensifies drought resistance by elevating antioxidant activities and photosynthesis, providing new insights into its function in drought response.

Summary: The role of paxillin in signal pathways in phytopathogenic fungi is not well understood. This study reveals that MoPax1 activates MAP kinase signaling pathways and autophagy through its interaction with MoMka1, and plays an important role in appressorium-mediated plant infection by the rice blast fungus.

Summary: In this study, the protective effects of DADS against 1,3-DCP-induced hepatotoxicity and oxidative damage were investigated. The results showed that DADS treatment inhibited the increase in serum aminotransferase levels and reduced histopathological alterations in the liver induced by 1,3-DCP. Additionally, DADS treatment reduced 1,3-DCP-induced apoptotic changes in the liver and inhibited phosphorylation of MAPKs. These protective effects may be related to the inhibition of CYP2E1 expression, enhancement of antioxidant enzyme activity, and reduction of apoptotic activity.

Summary: This study investigated the pharmacodynamic effects of modified Gexiazhuyu decoction (MGXZYD) and its underlying mechanism in the treatment of chronic salpingitis. The results showed that MGXZYD improved the pathological damage and fibrosis of the oviduct, decreased inflammation, and prevented the progression of chronic salpingitis by inhibiting the p38 MAPK signaling pathway.

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.
