Ovarian cancer is a fatal gynecological cancer and a major cause of cancer-related mortality worldwide. The main limitation to a successful treatment for ovarian cancer is the development of drug resistance to combined chemotherapy. Tumor suppressor genes (TSGs) are wild-type alleles of genes which play regulatory roles in diverse cellular activities, and whose loss of function contributes to t...

conclusions presence of drug resistance mutations among the patients was significant. precore mutations were common amongst iranian hbv chronic carriers under lamivudine therapy and these mutations were accompanied by clinical relapse. patients and methods sequential sera were obtained from 88 chronic hbv carriers who received lamivudine for more than 24 months. polymerase and precore regions w...

background: acinetobacter baumannii is commonly resistant to nearly all antibiotics due to presence of antibiotic resistance genes and biofilm formation. in this study we determined the presence of certain antibiotic-resistance genes associated with biofilm production and the influence of low iron concentration on expression of the biofilm-associated protein gene (bap) in development of biofilm...

The recent treatment of hematological malignancies appears to be unsatisfactory in child and adult patients with acute myeloid leukemia and adult patients with acute lymphocytic leukemia. A major problem in the treatment of leukemia is caused by the development of drug resistance to chemotherapeutic agents, which is already present at diagnosis or after chemotherapy as a minimal residual diseas...

Drug resistance is the leading cause of death in prostate cancer patients. Therefore, exploring mechanism underlying drug and identifying novel therapeutic targets are urgently needed. Long non-coding ribonucleic acid disrupted renal carcinoma 3 acts as a tumor suppressor gene several types. However, to date, no study has investigated biological function long cancer. Gene expression was detecte...

UNLABELLED Entry inhibitors represent a potent class of antiretroviral drugs that target a host cell protein, CCR5, an HIV-1 entry coreceptor, and not viral protein. Lack of sensitivity can occur due to preexisting virus that uses the CXCR4 coreceptor, while true resistance occurs through viral adaptation to use a drug-bound CCR5 coreceptor. To understand this R5 resistance pathway, we analyzed...
