Glioblastoma (GBM) is a highly aggressive brain tumor with frequent recurrence, yet the molecular mechanisms driving recurrence remain poorly understood. Identifying recurrence-associated genes may improve prognosis and treatment strategies. We applied weighted gene co-expression network analysis (WGCNA) to transcriptomic data from IDH-wildtype histological GBM in the CGGA-693 (n = 190) and CGGA-325 (n = 111) cohorts to identify recurrence-associated genes.

An imbalance in the microbiota-gut-brain axis exerts an essential effect on the pathophysiology of depressive and anxiety disorders. Our previous research revealed that the timing of inulin administration altered its effects on chronic unpredictable mild stress (CUMS)-induced anxiety and depression. However, it is still unclear if the gut-brain axis is primarily responsible for these effects.

Article Synopsis
  • - The study aimed to explore factors related to post-stroke depression (PSD) in patients after COVID-19 restrictions were eased, focusing on 947 stroke patients.
  • - Results showed a 14.15% prevalence of PSD, with significant associations found between depression and factors like TSH levels, CRP, family history of stroke, migraine history, and shorter sleep duration.
  • - The findings suggest that CRP, family stroke history, migraine, sleep duration, and TSH are independent risk factors for developing PSD as restrictions ease.

Chiral amino acids and their deamination products, α-keto acids, have important applications in food, medicine, and fine chemicals. In this study, two l-amino acid deaminase genes from Proteus mirabilis, PM473 of type Ⅰ and PM471 of type Ⅱ were cloned and expressed in Escherichia coli respectively, expected to achieve the chiral separation of amino acids. Extensive substrate preference testing showed that both deaminases had catalytic effects on the d-amino acid component of the D, l-amino acids, and PM473 has a wider catalytic range for amino acids.
