Hypofunction of macrophage chemotaxis contributes to defective efficacy of herceptin in HER2-positive breast cancer patients.

Breast cancer was considered as a kind of prone breast tumors with the complicated pathological mechanisms and diverse clinical classifications. In the clinical treatments of HER2-positive tumor patients, HER2 monoclonal antibodies, such as Herceptin, have shown well-defined therapeutic effects. Nevertheless, due to the heterogeneity of breast cancers, drug resistance inevitably appeared during the application of Herceptin.

Effect of Wuziyanzong pill on metabolism of dapoxetine in vivo and in vitro.

In vitro incubation of rat liver microsomes with 30 μL of 100 μmol·L dapoxetine and 30 μL of 10, 100, 250, 500, 1000, 2500, or 5000 μg·mL Wuziyanzong pill was performed at 37 °C for 60 min. Dapoxetine concentration was analyzed by high performance liquid chromatography (HPLC). The half maximal inhibitory concentration (IC) of Wuziyanzong pill on metabolism of dapoxetine was 296.

Knockout of CNR1 prevents metabolic stress-induced cardiac injury through improving insulin resistance (IR) injury and endoplasmic reticulum (ER) stress by promoting AMPK-alpha activation.

Obesity and diabetes are associated with diabetic cardiomyopathy (DCM). However, the pathogenesis of DCM is not fully understood. Cannabinoid receptor gene (CNR1) has been a drug target for the treatment of obesity.

Design of amphiphilic PCL-PEG-PCL block copolymers as vehicles of Ginkgolide B and their brain-targeting studies.

The amphiphilic PEG-b-PCL block copolymers were synthesized by ring-opening polymerization. The specific and selective antagonists of platelet activating factor, Ginkgolide B (GB), was successfully encapsulated in the synthesized PEG-PCL nanoparticles (NPs) with high Encapsulation Efficiency and Drug Loading. The synthesis of different PEG-PCL copolymers were confirmed with FTIR and H NMR spectra.

[Expression of aldolase of Toxoplasma gondii and preparation of the polyclonal antibodies against this protein].

Aim: To produce the aldolase protein and its polyclonal antibody.

Methods: Aldolase gene was obtained from cDNA library by PCR amplification and subcloned to vector pET30a. The recombinant protein aldolase-His(6); was expressed in E.
