The role of acetylation and deacetylation in cancer metabolism.

Clin Transl Med

January 2025

Department of Obstetrics and Gynecology, Shengjing Hospital of China Medical University, Shenyang City, Liaoning Province, China.

As a hallmark of cancer, metabolic reprogramming adjusts macromolecular synthesis, energy metabolism and redox homeostasis processes to adapt to and promote the complex biological processes of abnormal growth and proliferation. The complexity of metabolic reprogramming lies in its precise regulation by multiple levels and factors, including the interplay of multiple signalling pathways, precise regulation of transcription factors and dynamic adjustments in metabolic enzyme activity. In this complex regulatory network, acetylation and deacetylation, which are important post-translational modifications, regulate key molecules and processes related to metabolic reprogramming by affecting protein function and stability.

The eukaryotic ribosome is a large ribonucleoprotein complex consisting of four types of ribosomal RNA (rRNA) and approximately 80 ribosomal proteins (RPs), forming the 40S and 60S subunits. In all living cells, its primary function is to produce proteins by converting messenger RNA (mRNA) into polypeptides. In addition to their canonical role in protein synthesis, RPs are crucial in controlling vital cellular processes such as cell cycle progression, cellular proliferation, differentiation, DNA damage repair, genome structure maintenance, and the cellular stress response.

Ischemia-reperfusion injury is a serious clinical pathology involving multiple organs such as the heart and brain. The injury results from oxidative stress, inflammatory response and cell death triggered by restoring tissue blood flow after ischemia, leading to severe cell and tissue damage. In recent years, the volume-regulated anion channel (VRAC) has gained attention as an important membrane protein complex.

Department of Thoracic/Head and Neck Medical Oncology, the University of Texas, MD Anderson Cancer Center, Houston, TX, USA.

Immune-checkpoint inhibitors (ICIs) have transformed the treatment paradigm for advanced-stage squamous non-small-cell lung cancer (LUSC), a histological subtype associated with inferior outcomes compared with lung adenocarcinoma. However, only a subset of patients derive durable clinical benefit. In the first-line setting, multiple ICI regimens are available, including anti-PD-(L)1 antibodies as monotherapy, in combination with chemotherapy, or with an anti-CTLA4 antibody with or without chemotherapy.

Circular RNA (circRNA) was first discovered in viruses in 1974, they are primarily formed through back-splicing, where a downstream splice donor is joined to an upstream splice acceptor, resulting in a closed circRNA transcript. Under normal conditions, most circRNAs are stably expressed, however, in pathological conditions, circRNAs can play critical roles in the disease process of multiple myeloma (MM) through mechanisms such as competing endogenous RNAs (ceRNAs), regulation of transcription and splicing, affecting protein expression and localization, and even direct encoding of peptides. In recent years, there has been increasing interest in the role of circRNAs in MM and their regulatory functions during the disease process.

Department of Gastroenterology and Medical Research Center, Liaoning Key Laboratory of Research and Application of Animal Models for Environmental and Metabolic Diseases, ShengJing Hospital of China Medical University, SanHao Street No. 36, HePing District, Shenyang, 110000, Liaoning, China.

The lack of knowledge about the mechanism of hyperoxia-induced intestinal injury has attracted considerable attention, due to the potential for this condition to cause neonatal complications. This study aimed to explore the relationship between hyperoxia-induced oxidative damage and ferroptosis in intestinal tissue and investigate the mechanism by which hyperoxia regulates inflammation through ferroptosis. The study systematically evaluated the effects of hyperoxia on oxidative stress, mitochondrial damage, ferroptosis, and inflammation of intestinal epithelial cells both in vitro and in vivo.
