MetabolomicsCDK4/6 inhibitor-mediated cell overgrowth triggers an osmotic stress response and chronic p38MAPK activation to promote long-term cell cycle arrest

Cell size and the cell cycle are intrinsically coupled and abnormal increases in cell size are associated with senescence and permanent cell cycle arrest. The mechanism by which overgrowth primes cells to withdraw from the cell cycle remains unknown. We investigate this here using CDK4/6 inhibito...

MetabolomicsCell overgrowth potentiates osmotic and replication stresses to promote p38/p53/p21-dependent senescence
Abnormal increases in cell size are associated with senescence and cell cycle exit. The mechanisms by which overgrowth primes cells to withdraw from the cell cycle remain unknown. We address this question using CDK4/6 inhibitors, which arrest cells in G0/G1 and are licensed to treat advanced HR+/HER...

TranscriptomicsTranscriptional Profiling Defines the Roles of ERK and p38 Kinases in Epidermal Keratinocytes
Epidermal keratinocytes respond to extracellular influences by activating cytoplasmic signal transduction pathways that change the transcriptional profiles of affected cells. To define responses to two such pathways, p38 and ERK, we used SB203580 and PD98059 as specific inhibitors, and identified th...

TranscriptomicsSex-specific control of CNS autoimmunity by p38 MAPK signaling in myeloid cells
Objective: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS), characterized by a global increasing incidence driven by relapsing-remitting disease in females. p38 MAP kinase (MAPK) has been described as a key regulator of inflammatory respons...

MetabolomicsMulti-omics profiling identifies MAPK signaling suppression associated with tetracycline-induced root toxicity in soybean
Tetracycline (TC), a widely used veterinary antibiotic, is a pervasive emerging contaminant threatening crop production. Here, we employed integrated physiological, metabolomic, and transcriptomic analyses to decipher the response of soybean (Glycine max L.) to TC. While seed germination was unaffec...

TranscriptomicsComparative expression profiling identifies differential roles for Myogenin and p38M-NM-1 MAPK signaling in myogenesis
Mitogen activated protein kinase (MAPK) signaling regulates differentiation of many cell types. During myogenesis in particular, p38a MAPK (MAPK14) phosphorylates multiple transcriptional regulators to modulate muscle-specific gene expression. Among the p38a MAPK modulated genes is the muscle-specif...

TranscriptomicsTranscription profiling by array of left ventricle tissues from rat with overexpression of constitutively active upstream kinase mitogen-activated protein kinase kinase 3b (MKK3bE) and wild-type p38? in the heart
Mitogen-activated protein kinases (MAPKs) regulate cardiomyocyte growth and apoptosis in response to extracellular stimulation, but the downstream effectors that mediate their pathophysiological effects remain poorly understood. We determined the targets and role of p38 MAPK in the heart in vivo by ...

Proteomics,MultiomicsmiR-625-3p regulates oxaliplatin resistance by targeting MAP2K6-p38 signaling in human colorectal adenocarcinoma cells
Oxaliplatin (oxPt) resistance in colorectal cancers (CRC) is a major unsolved problem. Consequently, predictive markers and a better understanding of resistance mechanisms are urgently needed. To investigate if the recently identified predictive miR-625-3p is functionally involved in oxPt resistance...

Proteomicsp38-MAPK mediated rRNA processing and translation regulation enables PrE differentiation during mouse blastocyst maturation
p38-MAPKs are stress activated kinases necessary for placental development and nutrient and oxygen transfer during murine post-implantation development. In preimplantation development, p38-MAPK activity is required for blastocyst formation. Additionally, we have previously reported its role in regul...

MetabolomicsBisphenol mixture-induced DGKB downregulation promotes premature human neurogenesis through the activation of MAPK pathway

The widespread industrial transition from bisphenol A (BPA) to structural analogs such as BPS, BPE, and BPAF has raised significant concerns regarding their potential health risks. However, their neurodevelopmental risks and underlying molecular mechanisms, particularly when present as complex m...
