Ischemic postconditioning has been described in both heart and brain. The first aim of this study was to evaluate the effects of Sevoflurane postconditioning (SP) on brain biochemical parameters, Bcl-2, Bax, c-Fos and Caspase-3 protein levels and Bcl-2, Bax, TNF-α and Caspase-3 mRNA expression in the middle cerebral artery occlusion model. Results showed that SP markedly decreased cerebral oxidative injury and improved immunity activity. In addition, SP significantly enhanced cerebral Bcl-2, c-Fos and decreased Bax, Caspase-3 proteins positive expression. Reverse transcription polymerase chain reaction analysis showed that SP markedly enhanced Bcl-2, and decreased Bax, TNF-α and Caspase-3 mRNA expression. Our results confirm that SP can play the protective action against cerebral ischemia reperfusion-induced brain injury by regulating cerebral antioxidant enzymes activities, Bcl-2, Bax, c-Fos and Caspase-3 protein positive expression levels and Bcl-2, Bax, TNF-α and Caspase-3 mRNA expression.

FASN inhibition shows the potential for enhancing radiotherapy outcomes by targeting glycolysis, AKT, and ERK pathways in breast cancer.
Int J Radiat Biol
January 2025
Department of Biomedical Imaging and Radiological Sciences, National Yang Ming Chiao Tung University, Taipei City, Taiwan.
Purpose: Breast cancer ranks as the most prevalent cancer in women, characterized by heightened fatty acid synthesis and glycolytic activity. Fatty acid synthase (FASN) is prominently expressed in breast cancer cells, regulating fatty acid synthesis, thereby enhancing tumor growth and migration, and leading to radioresistance. This study aims to investigate how FASN inhibition affects cell proliferation, migration, and radioresistance in breast cancer, as well as the mechanisms involved.

College of Animal Science and Technology, Henan University of Science and Technology, Luoyang, China.
Background: As an opportunistic bacterial pathogen, Klebsiella pneumoniae (KP) is prone to causing a spectrum of diseases in rabbits when their immune system is compromised, which poses a threat to rabbit breeding industry. Bacillus coagulans (BC), recognized as an effective probiotic, confers a variety of benefits including anti-inflammatory and antioxidant properties.
Aim: The purpose of this study was to investigate whether dietary BC can effectively alleviate hepatic injury caused by KP.
The M1/M2 Macrophage Polarization and Hepatoprotective Activity of Quercetin in Cyclophosphamide-Induced Experimental Liver Toxicity.
Vet Med Sci
January 2025
Department of Medical Biology, Faculty of Medicine, Dicle University, Diyarbakir, Turkey.
Background: Chemotherapy drugs may lead to hepatic injury, which is considered one of the limitations of these drugs.
Objectives: The aim of this study was to evaluate the effect of quercetin (QUE) on M1/M2 macrophage polarization and hepatoprotective effect in cyclophosphamide (CTX)-induced liver toxicity.
Methods: Twenty-four mice were divided into four groups (Control, QUE, CTX, CTX + QUE).
Gengnianchun Against HO-Induced Oxidative Damage in KGN Cells via miR-548m/FOXO3 Signaling.
J Cell Biochem
January 2025
Department of Integrated Traditional Chinese Medicine and Western Medicine, The Obstetrics and Gynecology Hospital of Fudan University, Shanghai, China.
Gengnianchun (GNC) is a traditional remedy used for diminished ovarian reserve, but its underlying mechanisms remain unclear. This study aimed to explore these mechanisms in human granulosa-like cancer (KGN) cells pretreated with medicated rat serum (MRS) before HO exposure. MRS pretreatment significantly alleviated HO-induced cell damage, including improvements in cell viability, superoxide dismutase and GSH-Px activities, and Bcl-2 expression.

Institute of Basic Medical Sciences of Xiyuan Hospital, Beijing Key Laboratory of Chinese Materia Pharmacology, China Academy of Chinese Medical Sciences, National Clinical Research Center of Traditional Chinese Medicine for Cardiovascular Diseases, Beijing, China.
Objectives: This study intended to explore whether the protective effect safflower yellow injection (SYI) on myocardial ischemia-reperfusion (I/R) injury in rats mediated of the NLRP3 inflammasome signaling.
Methods: The I/R model was prepared by ligating the left anterior descending coronary artery for 45 min and then releasing the blood flow for 150 min. 96 male Wistar rats were randomly divided into sham group, I/R group, Hebeishuang group (HBS), SYI high-dose group (I/R + SYI-H), SYI medium-dose group (I/R + SYI-M) and SYI low-dose group (I/R + SYI-L).
