Asparagine endopeptidase (AEP) is ubiquitously expressed in both physiological and pathological contexts, yet its precise role and functional mechanism in breast cancer remain elusive. Here, we identified increased AEP expression in breast cancer tissues, which correlated with poorer survival rates and a propensity for lung metastasis among breast cancer patients. Loss of AEP impaired colony formation by breast cancer cells in vitro and suppressed lung metastasis in mice.

Heterozygotic mutations are responsible for various congenital diseases in the heart, pancreas, liver, and other organs in humans. However, there is lack of an animal that can comprehensively model these diseases since GATA6 is essential for early embryogenesis. Here, we report the establishment of a knockout zebrafish which recapitulates most of the symptoms in patients with mutations, including cardiac outflow tract defects, pancreatic hypoplasia/agenesis, gallbladder agenesis, and various liver diseases.

Malignant ascites (MA), a common and serious complication of various cancers in the abdominal cavity, originates from the extensive infiltration, metastasis, and growth of cancer cells in or on the abdominal cavity, leading to abnormal accumulation of fluid in the abdominal cavity and the formation of MA. MA seriously reduces the quality of life of cancer patients, shortens their survival period, and generally has a poor prognosis. Modern medicine has developed various strategies for the treatment of MA, including targeted supportive treatment, diuretic treatment, abdominal paracentesis, surgical intervention, and intraperitoneal administration therapy.

Department of Laboratory Medicine, The Sixth School of Clinical Medicine, The Affiliated Qingyuan Hospital (Qingyuan People's Hospital), Guangzhou Medical University, Qingyuan, China.

Triple-negative breast cancer (TNBC) is highly heterogeneous and poses a significant medical challenge due to limited treatment options and poor outcomes. Peroxisome proliferator-activated receptors (PPARs) play a crucial role in regulating metabolism and cell fate. While the association between PPAR signal and human cancers has been a topic of concern, its specific relationship with TNBC remains unclear.

Resolvin D1 (RvD1) is an endogenous anti-inflammatory mediator that modulates the inflammatory response and promotes inflammation resolution. RvD1 has demonstrated neuroprotective effects in various central nervous system contexts; however, its role in the pathophysiological processes of intracerebral hemorrhage (ICH) and the potential protective mechanisms when combined with exercise rehabilitation remain unclear. A mouse model of ICH was established using collagenase, and treatment with RvD1 combined with three weeks of exercise rehabilitation significantly improved neurological deficits, muscle strength, learning, and memory in ICH mice while reducing anxiety-like behavior.

Fibrates can prevent and treat ischemic stroke (IS), the occurrence and development of IS is closely related to hypoxia-inducible factor-1A (HIF-1A). However, the exact mechanism by which fibrates regulate HIF-1A to treat IS remains unclear. So network pharmacology and molecular docking were used to explore the mechanism by which fibrates regulate HIF-1A to treat IS, firstly, the structure of five fibrates were obtained by reviewing the literature and pharmacopoeia, then the potential targets of fibrates, IS, HIF1A and HIF1A-related genes were obtained through various databases, their common targets were obtained through Venny 2.

Advances of NAT10 in diseases: insights from dual properties as protein and RNA acetyltransferase.

Cell Biol Toxicol

December 2024

Department of Laboratory Medicine, Affiliated Qingyuan Hospital of Guangzhou Medical University, Qingyuan People's Hospital, Qingyuan, 511518, Guangdong, China.

N-acetyltransferase 10 (NAT10) is a member of the Gcn5-related N-acetyltransferase (GNAT) family and it plays a crucial role in various cellular processes, such as regulation of cell mitosis, post-DNA damage response, autophagy and apoptosis regulation, ribosome biogenesis, RNA modification, and other related pathways through its intrinsic protein acetyltransferase and RNA acetyltransferase activities. Moreover, NAT10 is closely associated with the pathogenesis of tumors, Hutchinson-Gilford progeria syndrome (HGPS), systemic lupus erythematosus, pulmonary fibrosis, depression and host-pathogen interactions. In recent years, mRNA acetylation has emerged as a prominent focus of research due to its pivotal role in regulating RNA stability and translation.

Although N-methyladenosine (mA) and its regulatory proteins were involved in multiple cellular damage processes, the roles of mA and its regulatory proteins in cadmium-induced pulmonary cell damage remain largely unknown. Our present data indicated that cadmium exposure caused serious damage in bronchial epithelial cells, as evidenced by reduction of cell viability and elevation of oxidative damage and apoptosis. These processes were accompanied by alterations of mA modification and its regulatory proteins (FTO, ALKBH5, YTHDC2).

Diabetic liver injury (DLI) refers to liver injury resulting from prolonged chronic hyperglycemia and represents a significant complication associated with diabetes, The specific pathogenic mechanism of DLI remains incompletely understood. Tumor necrosis factor α (TNF-α) has been demonstrated to play a crucial role in diabetic complications through intricate signalling pathways, including pyroptosis. However, it remains uncertain whether TNF-α mediates pyroptosis in DLI, we initially established an in vitro model of DLI and confirmed the presence of an inflammatory state characterized by TNF-α in DLI.

Understanding how climate, ecological and environmental changes, and anthropogenic activities have driven animals' development and predicting their prospective distribution profiles are essential to making a tangible conservation strategy. Macaques () distributed in China provide an ideal research model for such an effort. We reconstruct their geographic distribution profiles from the last inter-glaciation (LIG, 120,000-140,000 years BP), the Last Glacial Maximum (LGM, 22,000 years BP), and the present (1970-2000), based on which we deduce their distribution perspective in the 2050s.
