Monocyte-to-macrophage differentiation and subsequent foam cell formation are key processes that contribute to plaque build-up during the progression of atherosclerotic lesions. Palmitoylation enzymes are known to play pivotal roles in the development and progression of inflammatory diseases. However, their specific impact on atherosclerosis development remains unclear.

This study explores the therapeutic potential of low and high-molecular weight polysaccharides derived from in a murine model of lipoteichoic acid (LTA)-induced pneumonia, which represents bacterial-induced lung inflammation. Administration of polysaccharides effectively alleviated LTA-induced symptoms, including decreased lung and colon inflammation, and restored dysbiosis of gut microbiota.

DHA has been reported to have synergistic anticancer effects with a variety of drugs in the clinic; however, the molecular mechanism by which DHA inhibits tumorigenesis and improves oxaliplatin cytotoxicity in colon cancer cells is still not well understood. In this study, we found that DHA can inhibit cell proliferation and colony formation in a dose-dependent manner.

In addition, SIRT2, as the only sirtuin protein colocalized with tubulin in the cytoplasm, has its own functions and characteristics. In recent years, studies have increasingly shown that SIRT2 can participate in the regulation of gene expression and regulate signal transduction in the metabolic pathway mainly through its post-translational modification of target genes; thus, SIRT2 has become a key centre in the metabolic pathway and participates in the pathological process of metabolic disorder-related diseases.

The authors hypothesized that the NET has the advantages of the traditional ET (TET) and a reduced operation time. The purpose of this study is to compare the advantages and disadvantages of NET, TET and open surgery.

Methods: Patients aged 65 years and older with T1-2N0-1, hormone receptor-negative breast cancer in 2010-2015 were extracted from the Surveillance, Epidemiology, and End Results program. Propensity score matching was used to balance the baseline of different groups.
Background/aims: The aim was to characterize a bacterium causing intestinal mucosal barrier damage and to identify the possible invasion mechanism.
Materials And Methods: The intestinal permeability and tight junction protein levels were detected in guinea pigs infected with Escherichia coli D-09 via immunofluorescence analysis and western blotting. In order to explain this invasion mechanism at the gene level, whole genome sequencing analysis was performed on this bacterium.
Background: Although the results of gene testing can guide early breast cancer patients with hormone receptor (HR), human epidermal growth factor receptor 2 (HER2) to decide whether they need chemotherapy (CHT), there are still many patients worldwide whose problems cannot be resolved by genetic testing.
Methods: A total of 144,735 patients with HR, HER2, pT1-3N0-1 breast cancer from the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2015 were included. They were divided into CHT and no CHT groups, and after propensity score matching (PSM), overall survival (OS) and breast cancer-specific survival (BCSS) were tested using the Kaplan-Meier plot.
Background: The biological function and molecular mechanism of nucleolar spindle-associated protein 1 (NUSAP1) in breast cancer remain controversial, this study aimed to reveal the mechanism of NUSAP1 in breast cancer cell metastasis and survival.
Methods: The expression of NUSAP1 expression was evaluated by immunohistochemistry and quantitative real-time polymerase chain reaction (RT-qPCR) in breast tissue samples. The correlation of NUSAP1 expression with the clinicopathological parameters of the patients and overall survival (OS) was evaluated.
Myocardial injury is the primary manifestation of multiple organ dysfunction during sepsis, however, the mechanisms underlying sepsis‑induced myocardial injury remain unclear. Similarly, no effective therapeutics have yet been developed for myocardial injury. In the present study, the role of the NOD‑like receptor 3 (NLRP3) inflammasome on cardiac function were characterized and the effects of different ulinastatin (UTI) doses in protecting a septic rat model from myocardial injury were elucidated.
