Cancer stem cells are responsible for tumor recurrence and metastasis. A new highly reproducible procedure for human breast cancer MCF-7 stem cells (BCSC) isolation and selection was developed by using a combination of hypoxia/hypoglycemia plus taxol and adriamycin for 24h. The BCSC enriched fraction (i) expressed (2-15 times) the typical stemness protein markers CD44+, ALDH1A3 and Oct 3/4; (ii) increased its clonogenicity index (20-times), invasiveness profile (>70%), migration capacity (100%) and ability to form mammospheres, compared to its non-metastatic MCF-7 counterpart...

Retinoic acid receptor α (RARα) plays a crucial role in kidney disease. However, the underlying mechanisms in glomerulosclerosis (GS) is still not clear. The roles of RARα in an adriamycin (ADR)-induced GS rat model and in ADR-induced podocyte injury in vitro were investigated. RARα was over-expressed in GS rats, and serum, urine and kidney samples were collected to detect the induction of the expression of the receptor. RARα expression was inhibited and/or over-expressed in cultured podocytes following injury, as demonstrated by morphometric assays, cell toxicity, and matrix metalloproteinase (MMP) enzymatic activity...

Adriamycin (ADR) induces the over-expression of P-glycoprotein (P-gp) and multiple drug resistance in breast cancer cells. However, the biochemical process and underlying mechanisms are not clear. Our previous study revealed that ADR increased reactive oxygen species (ROS) generation and decreased glutathione (GSH) biosynthesis, while N-acetylcysteine, the ROS scavenger, reversed the over-expression of P-gp. The present study showed that ADR inhibited the influx of cystine (the source material of GSH) and the activity of the SLC7A11 transporter (in charge of cystine uptake) in MCF-7 cells...

Neoadjuvant chemotherapy aims to improve the outcome of breast cancer patients, but only few would benefit from this treatment. Pathological complete response has been proposed as a surrogate marker for the prediction of long-term clinical benefits; however, 50%-85% patients have an unfavorable pathological complete response to chemotherapy. MicroRNAs are known biomarkers of breast cancer progression; nevertheless, their potential to identify patients with pathological complete response remains poorly understood...

Injury of the glomerular filter causes proteinuria by disrupting the sensitive interplay of the glomerular protein network. To date, studies of the expression and trafficking of glomerular proteins have been mostly limited to in vitro or histologic studies. Here, we report a novel in vivo biotinylation assay that allows the quantification of surface expression of glomerular proteins in mice. Kidneys were perfused in situ with biotin before harvest. Afterwards glomeruli were isolated and lyzed. The protein of interest was separated by immunoprecipitation and the amount of surface-expressed protein was quantified by Western blot analysis with streptavidin staining...

Adriamycin is a first-line chemotherapy agent against cancer, but the development of resistance has become a major problem. Although autophagy is considered to be an adaptive survival response in response to chemotherapy and may be associated with chemoresistance, its inducer and the underlying molecular mechanisms remain unclear. Here, we demonstrate that adriamycin up-regulates the both levels of TRPC5 and autophagy, and the increase in autophagy is mediated by TRPC5 in breast cancer cells. Blockade of TRPC5 or autophagy increased the sensitivity to chemotherapy in vitro and in vivo...
