Soto J et. al. (June 2023). Reduction of Intracellular Tension and Cell Adhesion Promotes Open Chromatin Structure and Enhances Cell Reprogramming Adv Sci (Weinh). :e2300152.
In this study, researchers explored the impact of intracellular mechanotransduction through focal adhesions and the cytoskeleton on cell reprogramming. They found that reducing actin cytoskeletal tension or cell adhesion during the early phase of induced neuronal reprogramming promotes a more open chromatin structure, enhances the accessibility of neuronal gene promoters, and significantly improves the efficiency of cell conversion, highlighting the crucial role of mechanical properties in epigenetic regulation and cell fate determination.

Li F et. al. (June 2023). Down-regulated Smyd1 participated in the inhibition of myoblast differentiation induced by cigarette smoke extract Toxicol Lett. 383:98-111.
In this study, researchers investigated the role of the histone methyltransferase Smyd1 in cigarette smoke-induced inhibition of myoblast differentiation. They found that exposure to cigarette smoke extract (CSE) downregulated Smyd1 expression, leading to impaired myotube formation and dysregulation of key cellular processes, including apoptosis, pyroptosis, reactive oxygen species levels, mitochondrial biogenesis, and protein degradation. Overexpression of Smyd1 partially reversed the inhibitory effects of CSE, highlighting the involvement of the Smyd1-H3K4me2-P2RX7 axis in the detrimental effects of cigarette smoke on muscle differentiation.

Sharma S et. al. (July 2023). HDAC5 modulates SATB1 transcriptional activity to promote lung adenocarcinoma Br J Cancer.
In this study, the researchers identify SATB1 as an interacting protein of HDAC5 and demonstrate that HDAC5 deacetylates SATB1, leading to the downregulation of tumor suppressor genes and promotion of a malignant phenotype. Their findings provide insights into the molecular mechanisms by which SATB1 contributes to tumor growth and metastasis in a HDAC5-dependent manner in lung adenocarcinoma.

Jiang Y et. al. (July 2023). ECSIT Is a Critical Factor for Controlling Intestinal Homeostasis and Tumorigenesis through Regulating the Translation of YAP Protein Adv Sci (Weinh). :e2205180.
In this article, the researchers investigated the role of ECSIT in the regulation of intestinal homeostasis and tumorigenesis. They demonstrated that ECSIT depletion leads to dysregulated intestinal differentiation, enhanced translation of the Yes-associated protein (YAP), metabolic reprogramming, and increased tumorigenesis, highlighting the crucial role of ECSIT in maintaining intestinal balance and its potential as a prognostic marker in colorectal cancer.

Li F et. al. (June 2023) Enhancement of TKI sensitivity in lung adenocarcinoma through m6A-dependent translational repression of Wnt signaling by circ-FBXW7 Mol Cancer. 22(1):103.
The study identified a circular RNA, circ-FBXW7, that plays a role in enhancing sensitivity to tyrosine kinase inhibitors (TKIs) in lung adenocarcinoma (LUAD) by repressing the Wnt signaling pathway through m6A-dependent mechanisms. The findings suggest that targeting circ-FBXW7 and its polypeptide product circ-FBXW7-185AA can inhibit LUAD stem cells, reverse TKI resistance, and improve therapeutic strategies for LUAD treatment.

Zhang G et. al. (July 2023). NSUN2 stimulates tumor progression via enhancing TIAM2 mRNA stability in pancreatic cancer Cell Death Discov. 9(1):219.
In the article, NSUN2, an RNA methyltransferase, is found to be overexpressed in pancreatic cancer (PC) and associated with aggressive features. Silencing NSUN2 inhibits PC cell proliferation, migration, and invasion, while overexpression promotes PC growth and metastasis by enhancing the stability and transcription of TIAM2 mRNA, thereby promoting epithelial-mesenchymal transition (EMT) and suggesting the NSUN2/TIAM2 axis as a potential therapeutic target for PC.

In this study, the researchers investigate the effects of lotus leaf extracts on neoplastic transformation in murine skin cells. They find that the ethanol extract of lotus leaves activates the NRF2 pathway, upregulates antioxidant and detoxification enzymes, downregulates DNA methylation, and regulates histone acetylation, suggesting its potential as a chemopreventive agent against skin carcinogenesis.

In this study, the researchers investigate the regulatory role of SIRT2 in DNA-PK activation and its impact on DNA double-strand break repair. They demonstrate that SIRT2 deacetylation promotes DNA-PKcs localization to double-strand breaks, facilitating its interaction with Ku and promoting non-homologous end joining repair, and suggest that targeting SIRT2 may enhance the efficacy of radiation therapy in cancer treatment.

In this article, the researchers investigate the use of cell penetrant Cas9 ribonucleoproteins (RNPs) for genome editing in the mouse brain. They demonstrate that these transient RNPs can effectively edit neurons in the striatum, with reduced immune responses compared to viral vector-based delivery, highlighting their potential as a minimally immunogenic alternative for therapeutic genome editing in the central nervous system.

Kaur R et. al. (June 2023). Restriction of SARS-CoV-2 replication by receptor transporter protein 4 (RTP4) mBio. :e0109023.
In this study, researchers identified receptor transporter protein 4 (RTP4) as a host factor that restricts the replication of SARS-CoV-2, the virus responsible for COVID-19. They found that RTP4 inhibited viral replication by preventing the synthesis of viral RNA and binding to the viral genomic RNA, and it was effective against different variants of SARS-CoV-2. The discovery of RTP4 as a potential therapeutic target highlights its importance in the innate immune response against coronavirus infections.
