Red blood cells (RBCs)-based vesicles have been widely used for drug delivery due to their unique advantages. Intact RBCs contain a large amount of oxyhemoglobin (oxyHb), which can assist with photodynamic therapy (PDT). Indocyanine green (ICG), a photosensitizer both for photothermal therapy (PTT) and PDT, shows potent anticancer efficacy when combined with chemotherapeutic drug doxorubicin (DOX)...
Anthracycline/taxane-based chemotherapy regimens are usually used as neoadjuvant chemotherapies to decrease tumour size and prevent metastasis of advanced breast cancer. However, patients have a high risk of developing chemo-resistance during treatment through still unknown mechanisms. Glutathione S-transferase P1 (GSTP1), which belongs to the family of phase II metabolic enzymes, has been reported...
MicroRNAs (miRNAs) are a class of highly conserved small noncoding RNAs that play pivotal roles at the post-transcriptional level in the biological function of various cancers, including breast cancer. In our study, miR-346 mimic, inhibitor, negative control or si-SRCIN1 were transfected into MCF-7 and MCF-7/Doc cells, respectively. Quantitative real time PCR (qRT-PCR) was used to measure miR-346...
Chemoresistance mediated by miRNAs in breast cancer have been already validated by previous studies in vitro, while little is known concerning the expression of them in vivo. The aim of this study was to investigate the role of miR-222, miR-29a, miR-34a, miR-130a, miR-90b, miR-200b, miR-452, miR-197, miR-138, miR-210, miR-423, miR-4298, miR-4644, miR-139, miR-1246, miR-1268a, miR-140, miR-149, miR-3178,...
Metastasis is the leading cause of death among breast cancer (BCa) patients and triple negative breast cancer (TNBC) as one of BCa subtypes exhibits the worst survival rate due to its highly aggressive and metastatic behavior. A growing body of research has shown that the dynamic expression of microRNAs (miRNAs) was intimately associated with tumor invasion and metastasis. Recent studies have demonstrated...
Adriamycin (Adr) is a potent chemotherapeutic agent for chemotherapy of breast cancer patients. Despite impressive initial clinical responses, some developed drug resistance to Adr-based therapy and the mechanisms underlying breast cancer cells resistance to Adr are not well known. In our previous study, in vitro, we verified that miR-222 was upregulated in Adr-resistant breast cancer cells (MCF-7/Adr)...
