Smart albumin-loaded Rose Bengal and doxorubicin nanoparticles for breast cancer therapy.

To synthesise HSA-RB-DOX nanoparticles, measure its characteristics and preliminarily evaluate its anti-cancer effects. Doxorubicin (DOX) and Rose Bengal (RB) were co-delivered using albumin as a carrier. HSA-RB-DOX nanoparticles were prepared by RB-induced self-assembly of albumin.

Enhancement of cisplatin cytotoxicity by Retigeric acid B involves blocking DNA repair and activating DR5 in prostate cancer cells.

Retigeric acid B (RAB), a natural compound isolated from lichen, has been demonstrated to inhibit cell growth and promote apoptosis in prostate cancer (PCa) cells. The present study evaluated the function of RAB combined with clinical chemotherapeutic drugs in PCa cell lines by MTT assay, reverse transcription quantitative polymerase chain reaction and western blot analysis, and identified that RAB at low doses produced significant synergistic cytotoxicity in combination with cisplatin (CDDP); however, no marked synergism between RAB and the other chemotherapeutics was observed. Additional studies revealed that RAB exerted an inhibitory effect on DNA damage repair pathways, including the nucleotide excision repair and mismatch repair pathways, which are involved in the sensitivity to CDDP-based chemotherapy, as suggested by the significantly downregulated expression of certain associated repair proteins.

Strategies to release doxorubicin from doxorubicin delivery vehicles.

Doxorubicin (DOX) is one of the most effective cytotoxic anticancer drugs and has been successfully applied in clinics to treat haematological malignancies and a broad range of solid tumours. However, the clinical applications of DOX have long been limited due to severe dose-dependent toxicities. Recent advances in the development of DOX delivery vehicles have addressed some of the non-specific toxicity challenges associated with DOX.

Prodrug-based nano-drug delivery system for co-encapsulate paclitaxel and carboplatin for lung cancer treatment.

Context: Paclitaxel (PTX) and carboplatin (CBP) are widely used for the combined chemotherapy of non-small cell lung cancer (NSCLC). However, the development of multidrug resistance of cancer cells, as well as systemic toxic side effects resulting from nonspecific localization of anticancer drugs to non-tumor areas are major obstacles to the success of chemotherapy in treating cancers.

Objective: This study aimed to engineer a prodrug-based nano-drug delivery system for co-encapsulate hydrophilic (CBP) and hydrophobic anti-tumor drugs (PTX).

[Effect of fumigation therapy with yinxieling on T-bet and GATA-3 protein expression in the peripheral blood monocyte of patients with psoriasis vulgaris].

Objective: To evaluate the effect of fumigating with Yinxieling (YXL) in treating patients with psoriasis vulgaris and its influence on T-bet and GATA-3 protein expressions in peripheral blood monocyte (PBMC).

Methods: Western blot method was employed to detect the T-bet and GATA-3 protein expressions in PBMC of 30 psoriasis vulgaris patients before and after they received fumigation therapy with YXL, also in 25 healthy persons for controls. The therapeutic efficacy was observed and the relationship between PASI scores and levels of T-bet and GATA-3 analyzed.
