Glioblastomas (GBMs) are highly aggressive, infiltrative, and heterogeneous brain tumors driven by complex genetic alterations. The basic-helix-loop-helix (bHLH) transcription factors ASCL1 and OLIG2 are dynamically co-expressed in GBMs; however, their combinatorial roles in regulating the plasticity and heterogeneity of GBM cells are unclear. Here, we show that induction of somatic mutations in subventricular zone (SVZ) progenitor cells leads to the dysregulation of ASCL1 and OLIG2, which then function redundantly and are required for brain tumor formation in a mouse model of GBM.

Introduction: Evidence suggests that brief, skills-based behavioral interventions are effective at improving clinical outcomes related to substance use and HIV, but little data exists on whether such interventions can incidentally improve employment. We examined preliminary changes in employment over six months following Khanya, a brief peer-delivered behavioral intervention to reduce substance use and improve antiretroviral therapy (ART) adherence compared to enhanced treatment as usual (ETAU).

Methods: Adults living with HIV (N = 61) with at least moderate substance use and ART non-adherence were recruited from a primary care clinic in Khayelitsha, South Africa, a community with high rates of unemployment.

The Hedgehog (Hh) signaling pathway is fundamental to embryogenesis, tissue homeostasis, and cancer. Hh signals are transduced via an unusual mechanism: upon agonist-induced phosphorylation, the noncanonical G protein-coupled receptor SMOOTHENED (SMO) binds the catalytic subunit of protein kinase A (PKA-C) and physically blocks its enzymatic activity. By combining computational structural approaches with biochemical and functional studies, we show that SMO mimics strategies prevalent in canonical GPCR and PKA signaling complexes, despite little sequence or secondary structural homology.

To survive predation, animals must be able to detect and appropriately respond to predator threats in their environment. Such defensive behaviors are thought to utilize hard-wired neural circuits for threat detection, sensorimotor integration, and execution of ethologically relevant behaviors. Despite being hard-wired, defensive behaviors (i.

Regulators of G-protein signaling (RGS) are a family of approximately 30 proteins that bind to and deactivate the alpha subunits of G-proteins (G) by accelerating their GTP hydrolysis rates, which terminates G-protein coupled receptor (GPCR) signaling. Thus, RGS proteins are essential in regulating GPCR signaling, and most members are implicated as critical nodes in human diseases such as hypertension, depression, and others. Regulator of G-protein signaling 2 (RGS2), a member of the R4 family of RGS proteins, is overexpressed in many solid breast cancers, and its levels in prostate cancer significantly correlate with the metastatic stage and poor prognosis.

Article Synopsis
  • The COVID-19 pandemic significantly disrupted tuberculosis (TB) treatment, particularly impacting directly observed therapy (DOT) adherence programs in South Africa.
  • Data from a study comparing DOT adherence rates before (pre-COVID-19) and after (post-COVID-19 lockdown) revealed marked increases in non-adherence rates, with the highest non-adherence observed immediately after the first lockdown.
  • The findings suggest that the negative impact on DOT adherence persisted post-lockdown, highlighting the need for further investigation into the barriers that worsened treatment adherence during and after the pandemic.
