Mutations or homozygous deletions of MHC class II (MHC-II) genes are commonly found in B cell lymphomas that develop in immune-privileged sites and have been associated with patient survival. However, the mechanisms regulating MHC-II expression, particularly through genetic and epigenetic factors, are not yet fully understood. In this study, we identified a key signaling pathway involving the histone H2AK119 deubiquitinase BRCA1 associated protein 1 (BAP1), the interferon regulatory factor interferon regulatory factor 1 (IRF1), and the MHC-II transactivator class II transactivator (CIITA), which directly activates MHC-II gene expression.

Circular RNA (circRNA) has gained attention as a promising platform for mRNA vaccines due to its stability, sustained protein expression, and intrinsic immunostimulatory properties. This study aimed to design and optimize a circRNA cancer vaccine platform by screening for efficient internal ribosome entry sites (IRES) and enhancing circRNA translation efficiency for improved cancer immunotherapy. We screened 29 IRES elements to identify the most efficient one for immune cell translation, ultimately discovering the A (EV-A) IRES.

Colorectal cancer (CRC) is a leading cause of cancer-related mortality. Epigenetic modifications play a significant role in the progression of CRC. KAT7, a histone acetyltransferase, has an unclear role in CRC.

Alzheimer's disease (AD) is the most frequent form of dementia and represents an increasing global burden, particularly in countries like Indonesia, where the population has begun to age significantly. Current medications, including cholinesterase inhibitors and NMDA receptor antagonists, have modest effects on clinical symptoms in the early to middle stages, but there is no curative treatment available so far despite progress. Activating or repressing epigenetic modifications, including DNA methylation, histone modification and microRNA regulation, appears to play an important role in AD development.

Low temperatures are one of the critical conditions affecting the performance and distribution of plants. Exposure to cooling results in the reprogramming of gene expression, which in turn would be mediated by epigenetic regulation. Antarctica is known as one of the most severe ecosystems, but several climate models predict an increase in average temperature, which may positively impact the development of Antarctic plants; however, under warmer temperatures, plants' vulnerability to damages from low-temperature events increases.
