Synergistic Inhibition of Breast Cancer Cell Growth by an Epigenome-Targeting Drug and a Tyrosine Kinase Inhibitor.

Background: Epigenome-targeting drugs, for example, histone decetylases (HDACs) inhibitors, have been recently shown to induce apoptosis in a variety of cancer cells, which could potentially be used as anticancer therapy. Tyrosine kinase inhibitors (TKIs) have been widely used in clinical trials of various cancers. HDAC inhibitor vorinostat, TKIs dasatinib have been tested in pivotal phase 2 clinical trials in patients with breast cancer.

A multicenter, randomized, double-blind, placebo-controlled trial evaluating the efficacy and safety of Tong Luo Hua Shi capsule, a modernized Tibetan medicine, in patients with rheumatoid arthritis.

Background: Tong Luo Hua Shi (TLHS) is a new formulation of the traditional Tibetan medicine Wu-wei-gan-lu that has been used for the treatment of rheumatoid arthritis (RA) for hundreds of years in China. This study aimed to evaluate the efficacy and safety of TLHS in patients with RA.

Methods: This was a randomized, double-blind, placebo-controlled, dose-finding study performed in patients with active RA from five medical centers.

Synergistic inhibitory effect of berberine and d-limonene on human gastric carcinoma cell line MGC803.

This study aims at evaluating the anticancer effects of berberine hydrochloride (berberine) and d-limonene, alone and in combination, on human gastric carcinoma cell line MGC803 to determine whether berberine and d-limonene work synergistically and elucidate their mechanisms. MGC803 cells were treated with berberine and d-limonene, alone and in combination, for 24-48 h. The inhibitory effects of these drugs on growth were determined by MTT assay.

Opioid peptides and innate immune response in mollusc.

The nervous and the immune systems can exchange information through opioid peptides. Furthermore, some opioid peptides can function as endogenous messengers of the immune system, and participate in an important part in the regulation of the various components of the immune response. Since the capacity of immunocytes to release and respond to opioid neuropeptide messengers is not restricted to mammalian organisms, recent studies have indicated that invertebrate models have been particularly useful to understand the mechanisms of the immune response.

Effects of leucine-enkephalin on catalase activity and hydrogen peroxide levels in the haemolymph of the Pacific Oyster (Crassostrea gigas).

The nervous and immune systems of invertebrates can exchange information through neuropeptides. Furthermore, some opioid peptides can function as endogenous immune system messengers and participate in the regulation of the immune responses. The present study was designed to investigate the effects of leucine-enkephalin (L-ENK) on the activity of catalase (CAT) and hydrogen peroxide (H(2)O(2)) content in the haemolymph of the Pacific Oyster (Crassostrea gigas).
