Inactivation of glutathione -transferase alpha 4 blocks -induced bystander effect by promoting macrophage ferroptosis.

-infected macrophages produce 4-hydroxynonenal (4-HNE) that mediates microbiota-induced bystander effect (MIBE) leading to colorectal cancer (CRC). Glutathione -transferase alpha 4 (Gsta4), a specific detoxifying enzyme for 4-HNE, is overexpressed in human CRC and -induced murine CRC. However, the roles of Gsta4 in -induced colitis and CRC remain unclear.

Factorial invariance of college students' scores on the Lifestyle Practices and Health Consciousness Inventory.

Objective: The aims of the present study were to validate college students' scores on the Lifestyle Practices and Health Consciousness Inventory (LPHCI), a screening tool for appraising Global Wellness (combined mental and physical health) and test for differences in Global Wellness across key demographic variables associated with college student health.

Method: A non-probability sample of 708 college students across four campus locations in three different cities was recruited to test the LPHCI's psychometric properties.

Results: Factorial invariance testing demonstrated psychometric equivalence in the meaning of Global Wellness between college students across ethnicity, generational status, and help-seeking history.

Methylation Array Signals are Predictive of Chronological Age Without Bisulfite Conversion.

DNA methylation data has been used to make "epigenetic clocks" which attempt to measure chronological and biological aging. These models rely on data derived from bisulfite-based measurements, which exploit a semi-selective deamination and a genomic reference to determine methylation states. Here, we demonstrate how another hallmark of aging, genomic instability, influences methylation measurements in both bisulfite sequencing and methylation arrays.

Blocking of doublecortin-like kinase 1-regulated SARS-CoV-2 replication cycle restores cell signaling network.

Severe COVID-19 and post-acute sequelae often afflict patients with underlying co-morbidities. There is a pressing need for highly effective treatment, particularly in light of the emergence of SARS-CoV-2 variants. In a previous study, we demonstrated that DCLK1, a protein associated with cancer stem cells, is highly expressed in the lungs of COVID-19 patients and enhances viral production and hyperinflammatory responses.

Targeting Doublecortin-Like Kinase 1 (DCLK1)-Regulated SARS-CoV-2 Pathogenesis in COVID-19.

Host factors play critical roles in SARS-CoV-2 infection-associated pathology and the severity of COVID-19. In this study, we systematically analyzed the roles of SARS-CoV-2-induced host factors, doublecortin-like kinase 1 (DCLK1), and S100A9 in viral pathogenesis. In autopsied subjects with COVID-19 and pre-existing chronic liver disease, we observed high levels of DCLK1 and S100A9 expression and immunosuppressive (DCLK1S100A9CD206) M2-like macrophages and N2-like neutrophils in lungs and livers.
