Multidrug resistance (MDR) is a complex phenomenon in which many different genes regulating drug transport, cellular repair, detoxification and drug metabolism are involved. Nevertheless, in most drug resistant cell lines and cancer patients up-regulation of ABC-transporter genes such as MDR associated Protein (MRP1) gene could be at the basis of the drug resistance phenotype. We aimed to decre...
Background and Objective: The drug resistance mutations are key elements in the failure of long-term treatment of Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) infections. The mutation in the YMDD motif in the P gene of HBV is the most critical factor in antiviral drug (especially lamivudine) resistance. This study aimed to assess the YMDD motif and other polymerase gene mutati...

abstract background and objective: highly active antiretroviral therapy (haart) can effectively prevent the progression of hiv-1 replication and increase life expectancy. there are numerous causes of treatment failure and the leading one is drug resistance. thus, we aimed to determine the hiv rt gene drug resistance mutations in patients treated with antiretroviral medications. material and met...
Background: Chronic myeloid leukemia is a clonal myeloproliferative disease which is characterized by bcr/abl translocation. With the emergence of tyrosine kinase inhibitors such as imatinib mesylate, significant improvement has been made in treatment of this disease. However, drug resistance against this medicine is still an obstacle. SIRT1 is a gene with deacetylase activity which has been de...

Aim and Background: Candida Albicans is the most important cause of vulvovaginal candidiasis and resistance to azoles can occur via various mechanisms including, change in the ERG11 gene. This study aim was to identification of ERG11 gene mutations in drug resistant Candida albicans isolated from patients with Candida vaginitis and its association with infertility in Iranian women. Mat...
بیماری میوه سبز مرکبات توسط باکتری سخت کشت candidatus liberobacter asiaticus ایجاد می شود که اولین بار در چین توصیف شده است و در سال 1919 با نام رسمی huanglongbing معرفی گردید. این بیماری یکی از پرخسارت ترین بیماری های مرکبات درجنوب شرقی آسیا، شبه قاره هند، آفریقای جنوبی و شبه جزیره عربستان است. این بیماری در سال 1386 از جنوب ایران گزارش گردید. برای درک مکانیسم مولکولی برهمکنش میزبان-پاتوژن از ...
background and aims: lamivudine is amongst the antiviral for drug chronic hepatitis b treatment. during therapy with lamivudine, variants may emerge with ymdd mutation in the reverse transcriptase (rt) region of polymerase gene. this mutation might have a role in drug resistant for hbv. materials and methods: hbv dna extraction from serum sample of 88 patients, were subjected to nested pcr for ...
