DNA methylation is a key mechanism underlying epigenetic regulation. Fruit fly has been considered as a free DNA methylation organism until recently a few studies demonstrated that genomic methylated DNA is prevalent during the early embryonic development; but the overall methylation level in Drosophila is lower than in vertebrates and plants. The putative genomic DNA methylation systerm in Drosophila contains a methyltransferase termed dDNMT2 and a methyl-binding protein dMBD2/3. dDNMT2 shows significant homology to the mammalian methyltransferases DNMT2 family, and dMBD2/3 encodes a protein with distinct homology to mammalian methyl-binding proteins MBD2 and MBD3. Some studies also indicated that methylation pattern varies among different species of Drosophila. This article summarizes the recent progresses in studies of DNA methylation in Drosophila.

Plant architecture greatly contributes to grain yield, but the epigenetic regulation of plant architecture remains elusive. Here, we identified the maize (Zea mays L.) mutant plant architecture 1 (par1), which shows reduced plant height, shorter and narrower leaves, and larger leaf angles than the wild type.

Hepatocellular carcinoma (HCC) is a malignant tumour that poses a serious threat to human health and places a heavy burden on individuals and society. However, the role of GPC1 in the malignant progression of HCC is unknown. In this study, we analysed the expression of GPC1 in HCC, and its association with poor patient prognosis.

The shift toward a histo-molecular approach in World Health Organization classification of central nervous system tumors (WHO CNS5) emphasizes the critical role of molecular testing, such as next-generation sequencing (NGS) and DNA methylation profiling, for accurate diagnosis. However, implementing these advanced techniques is particularly challenging in resource-constrained countries. To address this, the Asian Oceanian Society of Neuropathology committee for Adapting Diagnostic Approaches for Practical Taxonomy in Resource-Restrained Regions (AOSNP-ADAPTR) was initiated to help pathologists in resource-limited regions to implement WHO CNS5 diagnoses using simpler diagnostic tools, mainly immunohistochemistry.

DNA methylation is an epigenetic mechanism that regulates gene expression and is implicated in diseases such as cancer and atherosclerosis. However, traditional clinical methods for detecting DNA methylation often lack sensitivity and specificity, making early diagnosis challenging. Nanomaterials offer a solution with their unique properties, enabling highly sensitive photochemical and electrochemical detection techniques.

Objectives: The association between leisure-time physical activity (LTPA) and a lower risk of mortality is susceptible to bias from multiple sources. We investigated the potential of biological ageing to mediate the association between long-term LTPA and mortality and whether the methods used to account for reverse causality affect the interpretation of this association.
Methods: Study participants were twins from the older Finnish Twin Cohort (n = 22,750; 18-50 years at baseline).
