Cervical cancer (CC) is a very usual reproductive malignant tumor in women. RNA polymerase II-associated factor 1 (PAF1) and flotillin-2 (FLOT2) both have been discovered to key participators in cancers' progression. However, the effects of PAF1/FLOT2 axis on CC development have not been probed. In this study, PAF1 and FLOT2 exhibited higher expression, and silencing of PAF1 down-regulated FLOT2 expression in CC. In addition, the regulatory effects of PAF1 suppression on CC progression were reversed after FLOT2 overexpression. Next, inhibition of PAF1 slowed the tumor growth in vivo through modulating FLOT2. Besides, down-regulation of PAF1 reduced FLOT2 expression to retard the MEK/ERK1/2 pathway. In conclusion, knockdown of PAF1 suppressed CC progression via retarding FLOT2-mediated MEK/ERK1/2 pathway. Our findings illustrated that the PAF1/FLOT2 axis may be useful bio-targets for CC treatment.

Whisker-mediated tactile perception is essential for rodent navigation, food acquisition, and social interactions. However, the molecular mechanisms underlying tactile information processing, learning, and memory have not been studied to the same extent as for other modalities. Using immunohistochemical staining, we investigated changes in regional c-Fos expression as an index of neuronal activity and phosphorylated (p)ERK1/2 as an index of ERK1/2 activity in mice trained on a tactile-cued 8-arm radial maze task.

The PI3K-AKT and MEK-ERK signaling pathways are integral to fundamental cellular processes such as proliferation, viability, and differentiation. In granulosa cells (GCs), these pathways are activated by FSH and IGF1 through respective receptors. We investigated the comparative transcriptome changes induced by AKT and ERK pathways using corresponding inhibitors in GCs.

Human periodontal ligament cells (hPDLCs) express matrix metalloproteinases (MMPs), a group of enzymes responsible for the destruction of most extracellular matrix proteins in dental tissues, especially MMP-1, MMP-2, and MMP-13. Exploring the regulatory mechanism of MMPs is crucial for understanding external root resorption (ERR), one of the most severe complications, along with substantial loss of dental tissue, induced by trauma, pulpal infection, tooth bleaching, and orthodontic treatment, etc. Discoidin domain receptor 1 (DDR1), a cell surface receptor binding to collagen, has the potential to regulate the expression of MMP-1, MMP-2, and MMP-13, but the mechanism remains unclear.

Article Synopsis
  • Olanzapine (OLA) is an effective antipsychotic for schizophrenia and bipolar disorder, but it has serious side effects like liver damage and weight gain.
  • This study aimed to investigate the metabolic disruption caused by OLA and explore the protective roles of sulforaphane (SFN) and β-sitosterol (βSS) against these effects.
  • Results showed that SFN and/or βSS alleviated the adverse biochemical and liver function abnormalities caused by OLA by modulating specific cellular signaling pathways involved in metabolism and inflammation.
