Posttranslational modifications (PTMs) of histone proteins may result in altered epigenetic signaling after pediatric traumatic brain injury (TBI). Hippocampal histone H3 acetylation and methylation in immature rats after moderate TBI were measured and decreased only in CA3 at 6 h and 24 h with persistent methylation decreases up to 72 h after injury. Decreased histone H3 acetylation and methylation suggest altered hippocampal CA3 epigenetic signaling during the first hours to days after TBI.

Over the past few decades, microtubules have been targeted by various anticancer drugs, including paclitaxel and eribulin. Despite their promising effects, the development of drug resistance remains a challenge. We aimed to define a novel cell death mechanism that targets microtubules using eribulin and to assess its potential in overcoming eribulin resistance.

Histone acetylation is an important epigenetic modification, modulating the development of many tumors. However, the functions of most histone acetylation-related genes (HARGs) and their prognostic values in Ewing sarcoma (EWS) remain unclear. The current study aimed to investigate the prognostic values and potential functions of HARGs in EWS.

Although ovarian endometrioid carcinoma (OEC), frequently associated with endometrial endometrioid carcinoma (EEC), is often diagnosed at an early stage, the prognosis remains poor. The development of new, effective drugs to target these cancers is highly desirable. The bromodomain and extra-terminal domain (BET) family proteins serve a role in regulating transcription by recognizing histone acetylation, which is implicated in several types of cancer.

Brown adipose tissue (BAT) is responsible for non-shivering thermogenesis, but it is absent in some mammals, including pigs. During development, BAT progenitors are derived from paired box 7 (Pax7)-expressing somitic mesodermal stem cells, which also give rise to skeletal muscle. However, the intrinsic mechanisms underlying the fate decisions between brown fat and muscle progenitors remain elusive.

Hepatocellular carcinoma (HCC) is one of the common malignant tumors. Complement system has become a new focus of cancer research by changing the biological behavior of cancer cells to influence the growth of cancer. Recent studies reported the complement C5a-C5aR1 axis can promote the malignant phenotype of multiple tumors through various signaling pathways.
