Determination of the sequence of the human genome and knowledge of the genetic code have allowed rapid progress in the identification of mammalian proteins. However, far less is known about the molecular mechanisms that control expression of human genes and about the variations in gene expression that underlie many pathological states, including cancer.(More)
Two functional SNPs (SNP285G > C; rs117039649 and SNP309T > G; rs2279744) have previously been reported to modulate Sp1 transcription factor binding to the promoter of the proto-oncogene MDM2, and to influence cancer risk. Recently, a third SNP (SNP55C > T; rs2870820) was also reported to affect Sp1 binding and MDM2 transcription. In this large population(More)
Chemobrain refers to a cluster of cognitive deficits which affects almost 4-75% of chemotherapy-treated cancer patients. Sunitinib, an FDA-approved multityrosine kinase inhibitor, is currently used in treating different types of tumors. Despite being regarded as targeted therapy which blunts sustained angiogenesis in cancer milieu through inhibiting(More)
BACKGROUND MicroRNAs (miRNAs) have been repeatedly shown to play important roles in liver pathologies, including hepatitis, liver cirrhosis, and liver cancer. Egypt has the highest hepatitis C virus (HCV) infection rate worldwide, predominantly involving genotype-4. OBJECTIVES In this study, we attempted to characterize the miRNA profile of the poorly(More)
Acute myeloid leukemia (AML) is the most common type of leukemia in adults with the lowest survival rate of all the leukemias. It is a heterogeneous disease in which a variety of cytogenetic and molecular alterations have been identified. Some galectins were previously reported to have important roles in cancer-like neoplastic transformation, tumor cell(More)
