Abstract:

Introduction: Evidence suggests that Lysosome associated protein transmembrane 4B (LAPTM4B) contributes to the risk of numerous cancers. The present study aimed to find out the impact of LAPTM4B polymorphism on the risk of childhood acute lymphoblastic leukemia (ALL) in the southeastern Iranian population. Materials and Methods: A total of 230 subjects including 110 children diagnosed with ALL and 120 healthy children enrolled in this case-control study. Genomic DNA was extracted from the whole blood by salting out method. Genotyping of LAPTM4B polymorphism was performed by polymerase chain reaction (PCR). Results: The results showed that LAPTM4B polymorphism significantly increased the risk of ALL in codominant (OR=1.91, 95% CI =1.08-3.40, p=0.025, 1/2 vs 1/1), dominant (OR=2, 95%CI=1.14-3.54, p=0.014 1/2+2/2 vs 1/1), and allele (OR = 1.74, 95% CI = 1.10–2.75, p = 0.017, 2 vs 1) genetic models Conclusion: Conclusively, our findings showed that LAPTM4B polymorphism is the risk factor of childhood ALL in our population. Further studies with larger sample sizes and different ethnicities are needed to confirm our findings.

Presenting Clinical and Laboratory Data of Childhood Acute Lymphoblastic Leukemia

Abstract Background Leukemia is the most prevalent childhood cancer and Acute Lymphoblastic Leukemia (ALL) constitutes 75% of all cases. The most frequent presenting symptoms are fever, weight loss and pallor. Early detection of clinical symptoms positively affects timely diagnosis. The objectives of the present study were to assess frequency of presenting symptoms, laboratory data, immune ph...

Association of TPMT (rs1800460) Gene Polymorphism with Childhood Acute Lymphoblastic Leukemia in a Population from Guilan, Iran

Acute lymphoblastic leukemia (ALL) is a malignant transformation and proliferation of lymphoid progenitor cells in bone marrow and blood, which is mainly found in children. Thiopurine methyltransferase (TPMT) is a thiopurine drug metabolizer enzyme that is prescribed for the treatment of ALL. Several single nucleotide polymorphisms in the TPMT gene have been reported to be associated with the d...

Association of Acute Lymphoblastic Leukemia and MDR1 Gene Polymorphism in an Ethnic Iranian Population

Background: The frequency of the multi-drug resistance 1 (MDR1) gene C3435T polymorphism differs in various ethnical populations such as Asian, African, and Caucasians populations. A silent C3435T polymorphism in exon 26 of MDR1 has been reported to be associated with a decreased expression of P-gp in TT genotypes carriers compared with CC genotypes carriers. Materials and Methods: To evaluate ...

the study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...

Taq1 Polymorphism (rs731236) of Vitamin D Receptor Gene in Children with Acute Lymphoblastic Leukemia

Background: Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Several studies have shown that ALL occurs as a result of genetic abnormalities. 1, 25-Dihydroxyvitamin D3 as a secosteroid hormone plays an important role in different metabolic pathways. The normal function of vitamin D occurs via binding to a ligand-activated transcription factor i.e. vitamin D receptor (VDR)...

Lack of Association between the MiR146a Polymorphism and Susceptibility to Thai Childhood Acute Lymphoblastic Leukemia.

BACKGROUND MiRNAs, small non coding RNAs, play a role in the regulation of hematopoiesis, with effects on cell growth, differentiation, and apoptosis. In addition, MiRNAs are thought to play an important role in tumorigenesis. The miR146a G>C polymorphism can lead to alteration of miR146 expression, which appears to be associated with development and progression of several cancers. This study a...
