Celastrol Induces Ferroptosis by Regulating CERKL to Exert Anti-Gastric Cancer Effect.

Gastric cancer is a significant global health issue. Celastrol, a natural compound, has shown antitumor potential, but its molecular mechanism in gastric cancer remains unclear. In this study, we treated HGC-27 cells with celastrol and employed CCK8, colony formation, and Transwell assays, revealing its inhibitory effect on cell proliferation and migration.

SRF/SLC31A1 signaling promotes cuproptosis induced by celastrol in NSCLC.

Faced with the highly malignant challenge of lung cancer, traditional chemotherapeutic agents, although predominantly inducing apoptosis, are severely limited in their therapeutic effect by the overexpression of anti-apoptotic proteins in lung cancer. Recently discovered copper-induced non-apoptotic cell death, known as cuproptosis, represents a novel mechanism for regulating cell death. Whether Celastrol (Cel), a potential anti-tumor drug, can counter non-small cell lung cancer (NSCLC) through inducing cuproptosis remains to be thoroughly investigated.

Winter forage crops influence soil properties through establishing different arbuscular mycorrhizal fungi communities in paddy field.

Winter planting is promising for improving the utilization rate of fallow paddy fields in southern China by establishing arbuscular mycorrhizal fungi (AMF) communities. However, the effects of different winter forage crops on AMF community construction remain unknown. The AMF community establishment of different winter planting forage crops were conducted in oat, rye, Chinese milk vetch, and ryegrass, with winter fallow as a control.

Triptolide's impact on ACER1 signaling: Inducing autophagy for triple-negative breast cancer suppression.

Given the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (Her-2) in triple-negative breast cancer (TNBC) cells, the efficacy of targeted therapies is limited. In this study, we uncovered that triptolide (TP) effectively suppresses the migration and invasiveness of MDA-MB-231 cells by activating autophagic pathways. Western blotting analysis revealed that TP significantly reduced the expression levels of p62 protein, while simultaneously markedly increasing the expression levels of LC3B-II, BNIP3, BNIP3L, ATG5, and ULK1 proteins, strongly suggesting an enhancement of autophagic activity in the cells.

Celastrol inhibits angiogenesis and the biological processes of MDA-MB-231 cells via the DEGS1/S1P signaling pathway.

Celastrol (Cel) shows potent antitumor activity in various experimental models. This study examined the relationship between Cel's antivascular and antitumor effects and sphingolipids. CCK-8 assay, transwell assay, Matrigel, PCR-array/RT-PCR/western blotting/immunohistochemistry assay, ELISA and HE staining were used to detect cell proliferation, migration and invasion, adhesion and angiogenesis, mRNA and protein expression, S1P production and tumor morphology.

Triptolide Inhibits the Biological Processes of HUVECs and HepG2 Cells via the Serine Palmitoyltransferase Long Chain Base Subunit 2/Sphingosine-1-Phosphate Signaling Pathway.

Triptolide (TP) has demonstrated innumerous biological effects and pharmacological potential against different cancer types. Hepatocellular carcinoma has a high incidence in men, and its incidence is increasing year by year. Studies have shown that angiogenesis plays an important role in the formation of tumors and that angiogenesis is closely related to tumor growth and metastasis.

Symptomatic Infection is Associated with Prolonged Duration of Viral Shedding in Mild Coronavirus Disease 2019: A Retrospective Study of 110 Children in Wuhan.

Background: Information regarding viral shedding in children with coronavirus disease 2019 (COVID-19) was limited. This study aims to investigate the clinical and laboratory characteristics associated with viral shedding in children with mild COVID-19.

Methods: The clinical and laboratory information of 110 children with COVID-19 at Wuhan Children's Hospital, Wuhan, China, from January 30 to March 10, 2020, were analyzed retrospectively.

[Seizure outcome after surgery for medically intractable mesial temporal lobe epilepsy and its predictors].

Objective: To evaluate seizure outcome in patients receiving surgery for chronic medically intractable mesial temporal lobe epilepsy (MTLE) and analyze its possible predictors.

Methods: This retrospective study was conducted in patients with chronic medically intractable MTLE undergoing anterior temporal lobectomy (ATL) or selective amygdalohippocampectomy (SAH) in our department between September, 2011 and October, 2013. The patients were followed up for 3.

Comparison of tonal response properties of primary auditory cortex neurons of adult rats under urethane and ketamine anesthesia.

Objective: To compare tonal response properties of neurons in the primary auditory cortex of Sprague-Dawley rats anesthetized with urethane and ketamine-xylazine.

Methods: Forty-five female Sprague-Dawley rats (200-250 g) were randomized into two groups and anesthetized with urethane or ketamine-xylazine. Tone pips were chosen as the stimuli to obtain the action potentials of the single neurons by in vivo cell-attached recording.
