Targeting transforming growth factor-β2 by antisense oligodeoxynucleotide accelerates T cell-mediated tumor rejection in a humanized mouse model of triple-negative breast cancer.

Transforming growth factor-beta (TGF-β) pathway mediates suppression of antitumor immunity and is associated with poor prognosis in triple-negative breast cancer (TNBC). In this study, we generated a humanized animal model by transplanting human peripheral blood mononuclear cells into immunodeficient mice followed by inoculation of MDA-MB-231 cells and subsequently analyzed the role of TGF-β2 in the interaction between human T cells and human tumor cells. Following reconstitution of the human immune system, inhibition of TGF-β signaling by TGF-β2 antisense oligodeoxynucleotide (TASO) resulted in accelerated tumor growth inhibition.

Anti-Obesity Effect of 6,8-Diprenylgenistein, an Isoflavonoid of Cudrania tricuspidata Fruits in High-Fat Diet-Induced Obese Mice.

Obesity, which is characterized by excessive fat accumulation, is associated with several pathological disorders, including metabolic diseases. In this study, the anti-obesity effect of 6,8-diprenylgenistein (DPG), a major isoflavonoid of Cudrania tricuspidata fruits was investigated using high fat-diet (HFD)-induced obese mice at the doses of 10 and 30 mg/kg for six week. The body weight of the DPG-treated groups was significantly lower compared to the HFD-treated group.

Therapeutic effect of anti CEACAM6 monoclonal antibody against lung adenocarcinoma by enhancing anoikis sensitivity.

Carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) plays a crucial role in tumorigenesis of lung cancer. However, the therapeutic potential for anti CEACAM6 monoclonal antibody (mAb) has only been limitedly explored. Here, we evaluate the therapeutic potential of naked anti CEACAM6 mAb against lung adenocarcinoma.

Effect of Cordyceps militaris extract and active constituents on metabolic parameters of obesity induced by high-fat diet in C58BL/6J mice.

Ethnopharmacological Relevance: Cordyceps species which is well-known as 'winter worm summer grass' has long been used as tonics and stimulants to enhance energy, exhibiting a potential for energy metabolism. Clinical trials have suggested their beneficial effect on lipid metabolic disorders such as hyperlipidemia.

Materials And Methods: The effect of Cordyceps militaris on metabolic parameters was investigated using C58BL/6J mice induced by high-fat diet (HFD).

Green tea extract increases cyclophosphamide-induced teratogenesis by modulating the expression of cytochrome P-450 mRNA.

The effects of green tea extract (GTE) on the fetal development and external, visceral and skeletal abnormalities induced by cyclophosphamide were investigated in rats. Pregnant rats were daily administered GTE (100mg/kg) by gavage for 7 d, from the 6th to 12th day of gestation, and intraperitoneally administered with cyclophosphamide (11mg/kg) 1h after the final treatment. On the 20th day of gestation, maternal and fetal abnormalities were determined by Cesarian section.

Neuroprotective effects of the novel polyethylene glycol-hemoglobin conjugate SB1 on experimental cerebral thromboembolism in rats.

SunBio1 (SB1) is a novel polyethylene glycol-bovine hemoglobin conjugate. It is a small molecule that shows high oxygen-delivery capacity, and exhibits extended plasma half-life compared to hemoglobin alone, thus reducing renal toxicity. The aim of the present study was to evaluate potential neuroprotective effects of SB1 using a rat middle cerebral artery occlusion model.
