Evodiamine Suppresses ABCG2 Mediated Drug Resistance by Inhibiting p50/p65 NF-κB Pathway in Colorectal Cancer.

Evodiamine (Evo), extracted from the Chinese herbal medicine Evodia rutaecarpa, has cytotoxic effects on different types of human cancer cells. However, its effects on drug resistance and their molecular mechanism and therapeutic target in colorectal cancer are not well understood. In the present study, we observed that Evo inhibited cell growth and induced apoptosis in adose-and time-dependent manner in HCT-116/L-OHP cells.

miR200c attenuates P-gp-mediated MDR and metastasis by targeting JNK2/c-Jun signaling pathway in colorectal cancer.

MicroRNA-200c (miR200c) recently emerged as an important regulator of tumorigenicity and cancer metastasis; however, its role in regulating multidrug resistance (MDR) remains unknown. In the current study, we found that the expression levels of miR200c in recurrent and metastatic colorectal cancers were significantly lower, whereas the JNK2 expression was higher compared with primary tumors. We showed that in MDR colorectal cancer cells, miR200c targeted the 3' untranslated region of the JNK2 gene.

Zuo Jin Wan reverses P-gp-mediated drug-resistance by inhibiting activation of the PI3K/Akt/NF-κB pathway.

Background: Zuo-Jin-Wan (ZJW), a traditional Chinese medicine formula, has been identified to be effective against drug resistance in cancer. In the present study, we investigated the effect of ZJW on acquired oxaliplatin-resistant and the PI3K/Akt/NF-κB pathway in vitro.

Methods: We tested the dose-response relationship of ZJW on reversing drug-resistance by CCK-8 assay and flow cytometry analysis in vitro.

Effects of Jianpi Jiedu Recipe on reversion of P-glycoprotein-mediated multidrug resistance through COX-2 pathway in colorectal cancer.

Objective: To evaluate the underlying mechanism of Jianpi Jiedu Recipe (, JJR) in the reversion of multidrug resistance concerning colorectal cancer in vitro and in vivo.

Methods: Mice were treated orally with JJR at a daily 4.25 g/(kg·day) or injected with vinblastine (VCR) 2.

Anti-tumor activity and apoptosis-regulation mechanisms of bufalin in various cancers: new hope for cancer patients.

The induction of apoptosis in target cells is a key mechanism for most anti-tumor therapies. Bufalin is a cardiotonic steroid that has the potential to induce differentiation and apoptosis of tumor cells. Research on bufalin has so far mainly involved leukemia, prostate cancer, gastric cancer and liver cancer, and has been confined to in vitro studies.

[Changes of tongue and pulse parameters in 50 lung cancer patients treated with integrated traditional Chinese and Western medicine].

Objective: To observe the changes of tongue and pulse parameters in lung cancer patients after combined treatment with integrated traditional Chinese and Western medicine, and to probe into the application of the tongue and pulse parameters in evaluation of integrated traditional Chinese and Western medicine therapy on lung cancer patients.

Methods: Electropulsograms and tongue pictures of 50 lung cancer patients were examined by TP-I digital electropulsography. The tongue and pulse parameters of the patients, including the indexes of moistness and dryness, thinness and thickness, fissure, swollenness and emaciation, greasiness and likeness of curd, and power spectral ratios (PSRs) 1, 2, 3, 4 and cepstrum spectral ratios (CSRs) 1, 2, 3, 4, were observed after 1-month and 2-month treatment with Yifei Kangliu Oral Liquid (a compound traditional Chinese herbal medicine) plus chemotherapy, respectively.
