Auxin affects the shape of root systems by influencing elongation and branching. Because multidrug resistance (MDR)-like ABC transporters participate in auxin transport, they may be expected to contribute to root system development. This reverse genetic study of Arabidopsis thaliana roots shows that MDR4-mediated basipetal auxin transport did not affect root elongation or branching. However, im...
BACKGROUND The use of neo-adjuvant chemotherapy in treating osteosarcoma has improved patients' average 5 year survival rate from 20% to 70% in the past 30 years. However, for patients who progress after chemotherapy, its effectiveness diminishes due to the emergence of multi-drug resistance (MDR) after prolonged therapy. METHODOLOGY/PRINCIPAL FINDINGS In order to overcome both the dose-limit...
The MDR1 multidrug resistance gene confers resistance to natural-product anticancer drugs including paclitaxel. We conducted a clinical gene therapy study to determine whether retroviral-mediated transfer of MDR1 in human hematopoietic cells would result in stable engraftment, and possibly expansion, of cells containing this gene after treatment with myelosuppressive doses of paclitaxel. Patien...
سابقه و هدف: mdr1 امروزه به عنوان شناخته شده ترین ترانسپورتر دخیل در مقاومت دارویی در سرطان های مختلف مورد توجه قرار گرفته، اما اهمیت این پروتئین در سیستم های مختلف بدن و نقش عملکردی آن در سایر بیماری ها کم تر مورد بررسی واقع شده است. هدف از مطالعه حاضر بررسی نقشmdr1 در سیستم ایمنی و نیز اختلالات عصبی، و امکان استفاده از این پروتئین در درمان بیماری های مرتبط می باشد. مواد و روش ها: مقاله حاضر ب...
Overexpression of MDR1 efflux pump is a major mechanism contributing to drug resistance in Candida albicans, the most common human fungal pathogen. To elucidate the regulatory pathway of drug resistance, we have identified a negative regulator of MDR1 and named it Regulator of Efflux Pump 1 (REP1). Overexpression of REP1 in Saccharomyces cerevisiae increased susceptibility to fluconazole. Furth...
Overexpression of multidrug resistance 1 (MDR1) in cancer remains one of the major causes for the failure of chemotherapy. In the present study, we found that MyoD and PEA3 could activate P-glycoprotein (P-gp) expression in SGC7901 cells. Knockdown of MyoD and PEA3 attenuated MDR1 expression and increased the sensitivity of multidrug resistant cancer cells to cytotoxic drugs that were transport...
BACKGROUND For the first time we tested an association between the human multidrug resistance gene 1 (MDR1) polymorphisms (SNPs) and idiopathic pulmonary fibrosis (IPF). Several MDR1 polymorphisms are associated with pathologies in which they modify the drug susceptibility and pharmacokinetics. MATERIALS AND METHODS We genotyped three MDR1 polymorphisms of 48 IPF patients and 100 control subj...
Cancer cells acquire anticancer drug resistance during chemotherapy, which aggravates cancer disease. MDR1 encoded from multidrug resistance gene 1 mainly causes multidrug resistance phenotypes of different cancer cells. In this study, we demonstrate that JNK1/2 activation by an extract from the root of Morus alba L. (White mulberry) reduces doxorubicin-resistant MCF-7/Dox cell viability by inh...
Mitochondria, which evolved from a free-living bacterial ancestor, contain their own genomes and genetic systems and are produced from preexisting mitochondria by binary division. The mitochondrion-dividing (MD) ring is the main skeletal structure of the mitochondrial division machinery. However, the assembly mechanism and molecular identity of the MD ring are unknown. Multi-omics analysis of i...
To investigate the expression profiles of efflux transporters in human ocular tissues, quantitative real-time polymerase chain reaction, Western blotting, and immunohistochemistry were used to obtain the relative mRNA and protein expressions of various efflux transporters in human ocular tissues. The cornea, conjunctiva, irisciliary body (ICB), retina and choroid, human corneal epithelial cell ...
