Post-translational protein lactylation modification in health and diseases: a double-edged sword.

As more is learned about lactate, it acts as both a product and a substrate and functions as a shuttle system between different cell populations to provide the energy for sustaining tumor growth and proliferation. Recent discoveries of protein lactylation modification mediated by lactate play an increasingly significant role in human health (e.g.

Insight into increased risk of portal vein thrombosis in nonalcoholic fatty liver disease.

Nonalcoholic fatty liver disease (NAFLD) is one of the leading chronic liver diseases with increased morbidity and mortality rates for extrahepatic diseases (including cardiovascular disease, portal vein thrombosis, etc.). There is an increased risk of thrombosis in both the portal and systemic circulation in patients with NAFLD, independent of traditional liver cirrhosis.

Artificial intelligence empowers the second-observer strategy for colonoscopy: a randomized clinical trial.

Background: In colonoscopy screening for colorectal cancer, human vision limitations may lead to higher miss rate of lesions; artificial intelligence (AI) assistance has been demonstrated to improve polyp detection. However, there still lacks direct evidence to demonstrate whether AI is superior to trainees or experienced nurses as a second observer to increase adenoma detection during colonoscopy. In this study, we aimed to compare the effectiveness of assistance from AI and human observer during colonoscopy.

However, the efficacy of combining these indices to diagnose decompensated cirrhosis is unknown. This study involved 150 patients divided into AKI and non-AKI, and healthy individuals.

Preparation of Rhodium(III) complexes with 2(1H)-quinolinone derivatives and evaluation of their in vitro and in vivo antitumor activity.

A series of 2(1H)-quinolinone derivatives and their rhodium (III) complexes were designed and synthesized. All the rhodium (III) complexes exhibited higher in vitro cytotoxicity for Hep G2, HeLa 229, MGC80-3, and NCI-H460 human tumor cell lines than their ligands and cisplatin, and among them complex 9 was found to be selectively cytotoxic to tumor cells. Further investigation revealed that complex 9 caused cell cycle arrest at the G2/M phase and induced apoptosis, and inhibited the proliferation of Hep G2 cells by impeding the phosphorylation of epidermal growth factor receptor (EGFR) and its downstream enzymes.

Astrocytic adenosine 5'-triphosphate release regulates the proliferation of neural stem cells in the adult hippocampus.

Astrocytes are key components of the niche for neural stem cells (NSCs) in the adult hippocampus and play a vital role in regulating NSC proliferation and differentiation. However, the exact molecular mechanisms by which astrocytes modulate NSC proliferation have not been identified. Here, we identified adenosine 5'-triphosphate (ATP) as a proliferative factor required for astrocyte-mediated proliferation of NSCs in the adult hippocampus.

[Recent progress in neurobiological mechanisms of depression].

Revealing the neurobiological mechanism of depression has always been a big challenge in the field of neuroscience. Not only are depressive syndromes heterogeneous and their aetiologies diverse, but also some symptoms are impossible to reproduce in animal models. Nevertheless, great progress has been made on the understanding and treatment of depression in recent years.

The only proposed T-cell epitope derived from the TEL-AML1 translocation is not naturally processed.

Adoptive therapy with T-cell receptor (TCR)-engineered T cells is a promising approach in cancer treatment. While usage of T cells specific for tumor-associated antigens (TAAs) can lead to serious side effects because of autoimmunity, targeting true tumor-specific mutations, such as the products of translocations in leukemias, should reduce such a risk. A potentially ideal target might be the chimeric protein TEL-AML1, which results from the chromosomal translocation 12;21 and represents the most common fusion gene in childhood B-cell precursor acute lymphoblastic leukemia (BCP-ALL).

Transgenic mice with a diverse human T cell antigen receptor repertoire.

Because of tolerance mechanisms, it has been hard to identify the T cell receptors (TCRs) of high-avidity T cells against self (for example, tumor) antigens. TCRs that are specific for foreign human antigens from the nontolerant T cell repertoire can be identified in mice. Moreover, if mice are constructed to express the human TCR repertoire, they can be used to analyze the unskewed repertoire against human self antigens.
