Liu Y et. al. (May 2024). DNMT1-targeting remodeling global DNA hypomethylation for enhanced tumor suppression and circumvented toxicity in oral squamous cell carcinoma Mol Cancer. 23(1):104.
This study investigates the role of DNA methyltransferase 1 (DNMT1) in oral squamous cell carcinoma (OSCC) progression through global DNA methylation regulation. They discovered that DNMT1 expression increases during oral malignant transformation and that its inhibition significantly reduces tumor growth. DNMT1 overexpression was linked to cancer-specific DNA hypomethylation, while DNMT1 knockdown caused extensive genome-wide hypomethylation. This novel hypomethylation pattern disrupted the PI3K-AKT and CDK2-Rb pathways, enhancing anticancer efficacy and reducing toxicity compared to PI3K inhibitors. The study highlights DNMT1 as a crucial target for improving OSCC treatment outcomes.

Zhang K et. al. (May 2024). Serum IL-24 combined with CA125 as screening and prognostic biomarkers for NSCLC Cell Biol Int.
This study investigates the potential of serum IL-24 combined with CA125 as biomarkers for screening and prognosis of non-small cell lung cancer (NSCLC). Researchers analyzed the biological significance of interleukin-24 (IL-24) using The Cancer Genome Atlas data and collected serum samples from 150 NSCLC patients and 70 controls. They found that IL-24 acts as a tumor suppressor in NSCLC and that its levels negatively correlate with CA125 and the TNM stage of the disease. The combination of IL-24 and CA125 effectively distinguished NSCLC patients from healthy individuals and those with other lung diseases. This panel was also identified as an independent prognostic marker, highlighting its potential for noninvasive NSCLC screening and prognosis.

Li SY et. al. (May 2024). Integrated analysis of the DNA methylome and RNA transcriptome during the development of skeletal muscle in Duroc pigs BMC Genomics. 25(1):504.
This article examines DNA methylation and RNA expression in the skeletal muscle development of Duroc pigs with different average daily gains (ADGs). Using bisulfite sequencing and transcriptome analysis, researchers examined the longissimus dorsi muscle of eight pigs, divided into high (H) and low (L) ADG groups. They identified 316 genes with both differential methylation and expression. Key genes, LPAR1 and MEF2C, showed significant differences in methylation and expression levels between the groups, indicating their role in muscle development and growth differences in Duroc pigs.

Zhang D et. al. (May 2024). CsWRKY11 cooperates with CsNPR1 to regulate SA-triggered leaf de-greening and reactive oxygen species burst in cucumber Mol Hortic. 4(1):21.
The study investigates the role of the CsNPR1-CsWRKY11 module in regulating salicylic acid (SA)-triggered leaf de-greening and reactive oxygen species (ROS) burst in cucumber. Researchers found that under SA treatment, CsNPR1 recruits CsWRKY11, which binds to its own promoter to amplify the SA signal. This regulatory module then directly influences the expression of genes related to chlorophyll degradation and ROS biosynthesis, leading to leaf senescence and an ROS burst. The findings highlight the CsNPR1-CsWRKY11 module as a crucial component in the SA signaling pathway, providing new insights into SA-regulated processes in plants.

Zhao T et. al. (May 2024). Prenatal 1-Nitropyrene Exposure Causes Autism-Like Behavior Partially by Altering DNA Hydroxymethylation in Developing Brain Adv Sci (Weinh). :e2306294.
This article investigates the effects of prenatal exposure to 1-nitropyrene (1-NP), a pollutant from vehicle exhaust, on autism-like behaviors in mice. Researchers found that 1-NP exposure led to autism-like behaviors, reduced inhibitory synaptic transmission, and decreased GAD67-positive interneurons in the brain. The exposure also hindered interneuron migration by downregulating related genes and reducing their hydroxymethylation via TET enzyme inhibition. Supplementing with alpha-ketoglutarate (α-KG) reversed these effects and improved behaviors. The study suggests 1-NP exposure causes autism-like behaviors by altering DNA hydroxymethylation in developing brains.

Zhang Z et. al. (May 2024). circATAD2 mitigates CD8+ T cells antitumor immune surveillance in breast cancer via IGF2BP3/m6A/PD-L1 manner Cancer Immunol Immunother. 73(7):130.
The study examines the role of m6A-modified circATAD2 in breast cancer (BC) and its impact on immune surveillance. Researchers found that circATAD2 is upregulated in BC and linked to poor prognosis. Functionally, circATAD2 promotes immune evasion by reducing the killing effect of CD8+ T cells. Mechanistically, circATAD2 binds to the 3'-UTR of PD-L1 mRNA, which is recognized by the m6A reader IGF2BP3, enhancing PD-L1 mRNA stability and expression. These findings reveal the circATAD2/m6A/IGF2BP3/PD-L1 axis in BC, suggesting circATAD2 as a potential target for PD-L1-mediated BC therapy.

Mishra T et. al. (May 2024). Antiretroviral Therapy Suppresses RNA N6-Methyladenosine Modification in Peripheral Blood Mononuclear Cells from HIV-1-Infected Individuals AIDS Res Hum Retroviruses.
This study explores how antiretroviral therapy (ART) affects RNA N6-methyladenosine (m6A) modification in HIV-1-infected individuals' peripheral blood mononuclear cells (PBMCs). They found that m6A levels were significantly higher in untreated patients compared to those on ART or healthy donors. This increase did not correspond to changes in m6A-regulatory gene expression but did affect the expression of certain immune response genes. The study suggests that m6A modification may influence immune response gene expression during HIV-1 infection and ART.

Wang Q et. al. (May 2024). The demethylase ALKBH5 mediates ZKSCAN3 expression through the m6A modification to activate VEGFA transcription and thus participates in MNNG-induced gastric cancer progression J Hazard Mater. 473:134690.
This study investigates how the demethylase ALKBH5 influences ZKSCAN3 expression through m6A modification, activating VEGFA transcription and participating in MNNG-induced gastric cancer progression. MNNG, a direct carcinogen, promotes tumor progression, including migration, invasion, and cancer growth. ALKBH5 regulates m6A modification in ZKSCAN3 mRNA, enhancing ZKSCAN3 expression. This leads to increased binding of ZKSCAN3 to the VEGFA promoter, boosting VEGFA transcription and promoting cancer cell characteristics and progression. The ALKBH5-ZKSCAN3-VEGFA pathway is activated in MNNG-induced gastric carcinogenesis and could serve as a prognostic biomarker for gastric cancer.

Seinkmane E et. al. (May 2024). Circadian regulation of macromolecular complex turnover and proteome renewal EMBO J.
This article explores how circadian rhythms regulate protein turnover and proteome renewal. Despite the energy cost, maintaining protein balance is crucial for cell function and health. The research shows that in mammals, protein synthesis varies daily, aligning with protein degradation to renew the proteome while maintaining its composition. This process is vital for complex structures like the ribosome. Daily turnover rhythms make cells more sensitive to proteotoxic stress at specific times, potentially affecting the efficacy of cancer treatments. Overall, circadian rhythms help minimize the energy needed for protein balance by consolidating turnover processes temporally.
