Article Synopsis
  • Development of chemotherapy-induced peripheral neuropathy (CIPN) can complicate cancer treatment, leading to dose reductions or stopping therapy; Goshajinkigan (GJG), a traditional Japanese medicine, may help reduce these symptoms.
  • A study with 55 ovarian cancer patients tested two groups: one started GJG after experiencing grade 2 neuropathy, while the other took it a week before chemotherapy; the main goals were to assess sensory neuropathy severity and pain levels.
  • Results showed that patients starting GJG early (Group B) had fewer pain complaints, lower reliance on pain medications, and less persistent neuropathy six months later, suggesting that preventive use of GJG could be beneficial, but more research is needed for confirmation

Upregulation of nuclear factor κB (NFκB) signaling is a hallmark of aging and a major cause of age-related chronic inflammation. However, its effect on cellular senescence remains unclear. Here, we show that alteration of NFκB nuclear dynamics from oscillatory to sustained by depleting a negative feedback regulator of NFκB pathway, NFκB inhibitor alpha (IκBα), in the presence of tumor necrosis factor α (TNFα) promotes cellular senescence.

Prader-Willi syndrome (PWS) is a complex epigenetic disorder caused by the deficiency of paternally expressed genes in chromosome 15q11-q13. This syndrome also includes endocrine dysfunction, leading to short stature, hypogonadism, and obscure hyperphagia. Although recent progress has been made toward understanding the genetic basis for PWS, the molecular mechanisms underlying its pathology in obesity remain unclear.

Article Synopsis
  • The study aims to identify genetic biomarkers that can help differentiate between ovarian serous carcinoma (OSC) and ovarian clear cell carcinoma (OCCC), two distinct types of epithelial ovarian cancer with different characteristics.
  • Researchers analyzed RNA from 57 surgical specimens of EOC patients using DNA microarray technology to find gene expression differences between the two cancer types.
  • They identified 10 candidate genes that were up-regulated in OCCC compared to OSC, suggesting these genes could serve as effective diagnostic markers and may provide insights into the distinct behaviors of these carcinomas, including OCCC's resistance to chemotherapy.

Control of mRNA poly(A) tails is essential for regulation of mRNA metabolism, specifically translation efficiency and mRNA stability. Gene expression in maturing oocytes relies largely on post-transcriptional regulation, as genes are transcriptionally silent during oocyte maturation. The CCR4-NOT complex is a major mammalian deadenylase, which regulates poly(A) tails of maternal mRNAs; however, the function of the CCR4-NOT complex in translational regulation has not been well understood.

Prader-Willi syndrome (PWS), which is a complex epigenetic disorder caused by the deficiency of paternally expressed genes in chromosome 15q11-q13, is associated with several psychiatric dimensions, including autism spectrum disorder. We have previously reported that iPS cells derived from PWS patients exhibited aberrant differentiation and transcriptomic dysregulation in differentiated neural stem cells (NSCs) and neurons. Here, we identified SLITRK1 as a downregulated gene in NSCs differentiated from PWS patient iPS cells by RNA sequencing analysis.

Full-endoscopic (FE) lumbar interbody fusion (LIF) is now a widely used type of minimally invasive surgery (MIS). Although FE-LIF includes LIF with foraminoplasty via a Kambin's triangle approach (FE-KLIF) and LIF with foraminotomy via an interlaminar approach, these techniques are rarely discussed separately. This review evaluates the outcomes and complications of FE-KLIF reported in the literature.

Article Synopsis
  • c-Src tyrosine kinase is involved in various signaling pathways and is often overactive in many cancers, while v-Src, its oncogenic form, leads to disruptions in cell division, specifically cytokinesis.
  • The study investigates how v-Src causes Aurora B protein, which is crucial for proper cell division, to mislocalize during monopolar cytokinesis.
  • Findings reveal that v-Src reduces Aurora B's autophosphorylation and kinase activity, leading to its delocalization, suggesting v-Src indirectly inhibits Aurora B's function rather than directly modifying it.
