Summary: The invasiveness and drug resistance of pancreatic cancer are crucial in defining its malignant potential and impacting the microenvironment around the tumor. The upregulation of Ribonucleotide reductase large subunit M1 (RRM1) in gemcitabine-resistant cancer cells is associated with a worse prognosis for pancreatic cancer. This study demonstrates that histone acetylation plays a role in the regulatory mechanism leading to gemcitabine resistance and subsequent RRM1 upregulation. Furthermore, RRM1 activation promotes extracellular matrix remodeling and enhances the migratory and invasive potential of pancreatic cancer cells.

Summary: Recent studies have shown that epigenetic alterations, particularly histone acetylation, play a significant role in the pathogenesis of lymphoma. A HAscore model has been developed to analyze histone acetylation patterns in DLBCL, revealing that patients with a low HAscore have distinct tumor immune microenvironments and poorer prognoses. KAT2A has been identified as a potential biomarker related to immune infiltration and malignant pathways in DLBCL.

Summary: The study developed a chemical catalyst that can achieve histone acetylation in living cells without genetic manipulation, offering a new tool for studying epigenetic regulation. This chemical method competes with and suppresses normal chromatin function markers, providing insights into epigenetic mechanisms.

Summary: This study reveals that endothelial cell focal adhesion kinase (FAK) plays a role in regulating pancreatic ductal adenocarcinoma (PDAC) metastasis and impacting the outcome of gemcitabine treatment. The findings suggest the potential clinical utility of combinatorial endothelial cell FAK targeting with gemcitabine in controlling metastasis in PDAC patients.

Summary: The study found that flavanones and phytomedicine rich in flavanones play an important role in protecting pancreatic beta cells in advanced diabetes. Targeting histone acetylation by phytomedicine is a potential strategy to delay the development and progression of diabetes. The inhibition of histone acetylation through regulating AMPK-mediated p300 inactivation is critical for the protective role of naringenin and hesperetin.

Summary: Immune evasion plays a significant role in the progression and immune resistance of pancreatic cancer, and the role of HDAC in this process is crucial. Despite the lack of significant breakthrough in immunotherapy for pancreatic cancer, targeting HDAC to reverse immune evasion may be a potential strategy.

Summary: The study found downregulation of CYP2C9 in human esophageal squamous cell carcinoma. The epigenetic analysis revealed that inhibition of HDAC8 and HDAC1 could increase the expression of CYP2C9. Overexpression of CYP2C9 reduces the invasion and migration ability of ESCC cells.

Summary: Proper regulation of histone acetylation is crucial for sebocyte lipogenesis, with inhibitors of p300 histone acetyltransferase leading to decreased expression of key lipogenic genes and decreased lipid droplet formation. In contrast, inhibition of histone deacetylase promotes lipogenesis by increasing the expression of these genes. These findings suggest a potential therapeutic strategy for skin diseases related to excess sebum production.

Summary: Pancreatic ductal adenocarcinoma (PDA) is a leading cause of cancer-related deaths worldwide and its treatment is challenging due to a lack of durable responses to standard-of-care chemotherapies. Gemcitabine, a cornerstone in PDA treatment, faces resistance mechanisms that have not yet been overcome in patient care.

Summary: HDAC5 loss is associated with unfavorable prognosis in pancreatic cancer by regulating the expression of cPLA2 and arachidonic acid (AA). Deacetylation of GATA1 by HDAC5 represses cPLA2 expression. Dietary management along with cPLA2-targeted therapy can be an effective strategy for treating HDAC5-deficient pancreatic cancer.
