This study was aimed to explore the contribution of autophagy associated gene Beclin1 in the prognosis of myelodysplastic syndrome (MDS) by detecting the expression level of Beclin1 in bone marrow mononuclear cells (BMNC) from 40 MDS patients, 14 non-malignant anemia patients and 25 AML patients. The expression of Beclin1 mRNA was detected by real-time quantitative polymerase chain reaction (qRT-PCR). At the same time, the Western blot was used to analyze the expression of Beclin1 proteins. The results showed that the expression of Beclin1 in low risk MDS patients and non-malignant anemia patients was both significantly higher than that in acute myeloid leukemia patients (P < 0.01). And more interestingly, the Beclin1 mRNA expression in MDS group was negatively correlated with World Health Organization classification-based prognostic system (WPSS) score (r = -0.495). It is concluded that the expression of Beclin1 in the patients with MDS is higher than that in AML patients, and negatively correlated with WPSS scores. Beclin1 is a potential biomarker for predicting prognosis of the patients with MDS.

(MS) is an important pathogen that can cause respiratory diseases in poultry and birds, leading to serious economic losses in the world and impacting the development of the poultry industry. However, the pathogenic mechanisms of MS infection are still unclear, resulting in a lack of effective diagnosis and treatment strategies. This study aimed to uncover the infection effect caused by MS in chicken oviduct cells.

Objectives: To investigate the mechanism of luteolin for inhibiting proliferation of lung cancer A549 cells.
Methods: A549 cells treated with different concentrations of luteolin for 48 h were evaluated for changes in cell viability, proliferation, reactive oxygen species (ROS) production and apoptosis using MTT assay, plate cloning assay, EdU staining, DCFH-DA assay and Hoechst33258 staining. The changes in cell autophagy were examined with MDC staining, and the expressions of apoptosis-related proteins (Bax, Bcl-2, and cleaved caspase-9), autophagy-related proteins (LC3B, Beclin 1, and P62), AKT/mTOR pathway proteins, and HO-1 protein were detected using Western blotting.

Objectives: To explore the mechanism of Granules (QJZG) for improving thrombocytopenia in a mouse model of systemic lupus erythematosus (SLE).
Methods: Twenty-four MRL/lpr lupus mice were randomized equally into 4 groups for treatment with daily gavage of saline, QJZG or prednisone (Pred) or intraperitoneal injection (twice a week) of CaMKK2 activator, with 6 C57BL/6 mice with saline gavage as the control group. After 8 weeks of treatment, the mice were examined for PLT, PCT, PDW, MPV, serum levels of TPO, IL-6, IL-10, TNF-α and IFN-γ, and calcium ion fluorescence intensity using ELISA or flow-through assay.

Monosodium glutamate (MSG) is one of the most commonly used food additives, known for its adverse health effects. Alogliptin (ALO) is a highly selective dipeptidyl peptidase-4 inhibitor, but its role in male reproductive function remains debated. The study was designed to evaluate and compare the potential of ALO in mitigating MSG-induced testicular toxicity in juvenile and adult male rats.

Background: Stomach adenocarcinoma (STAD) is an aggressive malignancy characterized by high tumor plasticity and heterogeneity. This study investigates the role of Autophagy and Beclin 1 Regulator 1 (AMBRA1) in regulating tumor plasticity in STAD progression.
Methods: Combined with clinical data, the pan-cancer analysis of AMBRA1 was performed to analyze the role of AMBRA1 in STAD.
