Five blocks of farmer’s sugarcane fields were selected in district Jalandhar, Punjab during December 2016 to February 2017. These treated with 2% zinc phosphide (ZnP), ZnP+ 0.005% bromadiolone (Br), 0.25% triptolide (Tr) and Br+ Tr at cane maturation stage; 5th block was kept as untreated control. The post census % re-buildup rodents after 30 45 days treatment cut canes (%) significantly less r...

Treatment of solid tumors with combinations of chemotherapeutic agents has not led to significant increases in long-term survival. Recent studies support a role for inhibitors of checkpoint arrest as a means to enhance the cytotoxicity of chemotherapy. We have shown previously that triptolide (PG490), an oxygenated diterpene derived from a Chinese medicinal plant, induces apoptosis in cultured ...

Pneumonectomized rats injected with the alkaloid toxin, monocrotaline, develop progressive neointimal pulmonary vascular obliteration and pulmonary hypertension resulting in right ventricular failure and death. The antiproliferative immunosuppressant, triptolide, attenuates neointimal formation and pulmonary hypertension in this disease model (Faul JL, Nishimura T, Berry GJ, Benson GV, Pearl RG...

Transcription factor IIH (TFIIH) participates in transcription, nucleotide excision repair and the control of the cell cycle. In the present study, we demonstrate that the Dmp52 subunit of TFIIH in Drosophila physically interacts with the fly p53 homologue, Dp53. The depletion of Dmp52 in the wing disc generates chromosome fragility, increases apoptosis and produces wings with a reduced number ...

Tripterygium wilfordii Hook. f. is a traditional Chinese herb (Murphy, 2006; Qiu et al., 2003). The extract of Tripterygium wilfordii Hook. f. has been widely applied to the treatment of immune-related diseases, such as rheumatoid arthritis (RA), nephritis, and systemic lupus erythematosus (SLE) (Chang et al., 1999; Wang et al., 2000). Extracts of Tripterygium wilfordii Hook. f. have been shown...

Phytochemicals are a rich source of chemoprevention agents but their effects on modulating the Wnt/β-catenin signaling pathway have remained largely uninvestigated. Aberrantly activated Wnt signaling can result in the abnormal stabilization of β-catenin, a key causative step in a broad spectrum of cancers. Here we report the modulation of lithium chloride-activated canonical Wnt/β-catenin signa...

Triptolide (TP) often causes adverse reactions in the gastrointestinal tract when it is administered orally. This study aimed to prepare and optimize triptolide-loaded solid lipid nanoparticles (TP-SLN) with reduced gastric irritation. The microemulsion technique was used to formulate TP-SLN employing a five-level central composite design (CCD) that was developed for exploring the optimum level...
