Background: Transcription factor 7-like 2 (TCF7L2) variants seem to affect diabetes susceptibility through β-cell dysfunction, underlying basis of which has been considered to be β-cell dedifferentiation rather than apoptotic β-cell death. The Extracellular regulated protein kinases/Mitogen-activated protein kinase signaling pathway (ERK/MAPK signaling pathway) has been confirmed to be significantly associated with multiple cellular process, including cellular dedifferentiation. However, the effects of TCF7L2 on β-cell function and ERK/MAPK signaling pathway are poorly understood.

Article Synopsis
  • A phase II clinical trial suggested that telitacicept might effectively reduce proteinuria in patients with IgA nephropathy (IgAN), prompting a larger retrospective study to confirm its efficacy and safety.
  • The study followed 97 patients treated with telitacicept over three months, showing significant reductions in proteinuria at 2, 4, and 6 months compared to baseline, while eGFR levels remained stable.
  • The findings indicate that telitacicept can safely lower proteinuria, but further research in larger phase III trials is needed to assess long-term kidney protection.

Gestational Diabetes Mellitus (GDM), a serious complication during pregnancy which is defined by abnormal glucose regulation, is commonly treated by diabetic diet and lifestyle changes. While recent findings place the microbiome as a natural mediator between diet interventions and diverse disease states, its role in GDM is still unknown. Here, based on observation data from healthy pregnant control group and GDM patients, we developed a new network approach using patterns of co-abundance of microorganism to construct microbial networks that represent human-specific information about gut microbiota in different groups.
