Aim: Ginsenosides have notable bioactivity in treating cardiovascular diseases, but the mechanisms of their combined use with Peroxiredoxin 6 (PRDX6) in myocardial injury remain unclear. This study explores the synergistic effects of Ginsenoside Rb1 (Gs-Rb1) and PRDX6, aiming to provide a theoretical foundation for their therapeutic potential.
Methods: We established a rat model of isoproterenol (ISO)-induced myocardial injury and observed that combination therapy was more effective than single-drug treatments, as shown by ECG monitoring and Masson staining.
Background: The rising incidence of breast cancer and its heterogeneity necessitate precise tools for predicting patient prognosis and tailoring personalized treatments. Epigenetic changes play a critical role in breast cancer progression and therapy responses, providing a foundation for prognostic model development.
Methods: We developed the Machine Learning-derived Epigenetic Model (MLEM) to identify prognostic epigenetic gene patterns in breast cancer.

Background: Breast cancer remains a leading cause of mortality among women worldwide, emphasizing the urgent need for innovative prognostic tools to improve treatment strategies. Anoikis, a form of programmed cell death critical in preventing metastasis, plays a pivotal role in breast cancer progression.
Methods: This study introduces the Artificial Intelligence-Derived Anoikis Signature (AIDAS), a novel machine learning-based prognostic tool that identifies key anoikis-related gene patterns in breast cancer.
Objectives: This research aimed to study the expression of mRNA in hepatocellular carcinoma (HCC) and its effect on the prognosis of HCC. Moreover, the effect of gene knockdown on the proliferation, migration, and invasion of HepG2 cells mediated by lentivirus was also examined. This study offers a theoretical and experimental basis for further research on the mechanism of PRDX6 in liver cancer and new methods for clinical diagnosis and treatment.

The hypoxia-sensitive gastric cancer BGC-823 cells were identified and transfected in vitro with Hifectin II under hypoxic conditions, and the expression of survivin and HIF-1α was assessed by RT-PCR and Western blotting assays, respectively. The ability of apoptosis, proliferation, invasion, and migration was measured, and the results showed that HIF-1α expression was significantly increased in BGC-823 cells under hypoxic conditions, and survival-targeted siRNA transfection decreased the expression of survivin under hypoxic conditions, while co-transfection of survivin-targeted siRNA and HIF-1α-targeted siRNA down-regulated both survivin and HIF-1α expression.

Methods: The expression of GPX2 in lung adenocarcinoma and its effect on survival were analyzed by the TCGA database and the GEPIA 2 database. A total of 45 cases of primary lung adenocarcinoma tissue specimens and 45 cases of their paracancerous tissue specimens were collected, and the expression of GPX2 in the two types of tissues was detected by immunohistochemistry.
Aims: Peroxiredoxins (PRDX6) regulates the occurrence and progression of cancer. The aim of this study is to investigate the effect of PRDX6 knockdown on the biological behavior of human gastric cancer cell line BGC-823 cells.

Background: Peroxiredoxin 6 (PRDX6) is an important antioxidant enzyme, with a potential application value in the treatment of diseases caused by oxidative damage.
Methods: PRDX6 and a mutant (mPRDX6) were heterologously expressed by using an E.coli expression system and purified by Ni-affinity chromatography.
Vascular endothelial cell growth factor (VEGF)-C promotes tumorigenesis by allowing lymph node metastasis and lymphangiogenesis, among other actions. RNA interference (RNAi) is a novel technique for suppressing target gene expression and may increase the effectiveness of cancer treatments. The present study assessed the influence of VEGF-C RNAi on the apoptosis and proliferation of mouse breast cancer cells and .

The Cag Type IV secretion apparatus proteins in Helicobacter pylori can mediate the injection of effector CagA protein into eukaryotic target cells. Although this apparatus forms an important pathway for bacterium-host interaction, its assembly process in vivo is poorly understood, and the proteins which contribute to break the bacterial cell walls in Cag-PAI have not yet been identified. The cagγ gene in Cag-PAI is a unique member that contains a conserved SLT catalysis domain, which makes it an attracting question whether cagy gene has the capacity to digest the bacterial cell wall.

The nanos gene encodes a zinc-finger protein which is required for the migration and differentiation of primordial germ cells as well as for their fate maintenance. In this study, a 1913 bp nanos gene was cloned and characterized in silkworm (Bombyx mori). RT-PCR and Western blot analysis showed that the nanos was expressed in developing embryos and various silkworm larval tissues.

Peroxiredoxins (Prxs) are believed to play an important role in insects for protection against the toxicity of reactive oxygen species (ROS). A gene encoding a novel 1-Cys Prx was firstly identified and characterized from an expressed sequence tag database (EST) in the lepidopteran insect, Bombyx mori. The 1-Cys Prx of B.
