Investigation of the cytotoxic, anti-proliferative and anti-angiogenic effects of Toluhydroquinone on Caco-2 cell line.

Colorectal cancer is one of the most common types of cancer in the world. The treatment options for colorectal carcinoma generally consist of surgery, radiotherapy and chemotherapy. The drug resistance to chemotherapy agents used in the current cancer treatment has brought about the finding of new drug molecules from some plant and aquatic species in the treatment approaches.

Nonsense β-thalassemia mutation at codon 37 (TGG>TGA), detected for the first time in three Turkish cases.

Thalassemias are genetically heterogeneous group of disorders with reduced or absent production of globin. β-Thalassemia major can be caused by homozygosity or compound heterozygosity for β-globin gene mutation. Here we report, for the first time in Turkey, three cases who carry the nonsense β-thalassemia (β-thal) mutation at codon 37 (TGG>TGA; Trp→Stop) causing premature stop codon.

Detection of deletions and/or amplifications of genes related with lung cancer by multiplex ligation-dependent probe amplification (MLPA) technique.

Background: Lung cancer has the leading mortality rate among all cancers and it is the second most common cause of death following cardiovascular diseases.The aim of the study was determining deleted and/or amplified regions of 64 different loci previously associated with lung cancer, by using Multiplex Ligation-dependent Probe Amplification (MLPA).

Results: The most frequently seen deletions in lung cancerous tissues were in 2p, 3p, 13q, 17p, 16p and the most frequently seen amplifications were in 17q, 8p and 5q.

Performance of MLPA as a screening method for aneuploidy in uncultured amniocytes.

Objective: To test whether the Multiplex Ligation-dependent Probe Amplification (MLPA) technique can be used as a screening test for rapid diagnosis of aneuploidies in uncultured amniocentesis.

Material And Methods: In this prospective blind study, MLPA with chromosomes 13,18,21,X and Y specific probe mixes was performed in 500 amniotic fluid samples. Chromosome copy numbers were determined by analyzing size and peak area for each MLPA probe.

The analysis of the relationship between A1298C and C677T polymorphisms of the MTHFR gene with prostate cancer in Eskisehir population.

Prostate cancer is the most common cause of cancer deaths in men and is a major health problem worldwide. Methylene tetrahydrofolate reductase (MTHFR) plays an important role for folate metabolism and is also an important source for DNA methylation and DNA synthesis (nucleotide synthesis). The objective of this study was to investigate the relationship between the A1298C and C677T polymorphisms of the MTHFR gene and prostate cancer in the Turkish population.

Role of the AZFd locus in spermatogenesis.

To determine the prevalence of Y-chromosome microdeletions among infertile men and to correlate the clinical presentation of the men with specific deletions, microdeletion analysis in 53 infertile men (30 nonobstructive azoospermic, 23 severely oligozoospermic patients), and 100 age-matched, fathered normospermic men who had fathered children was performed by the multiplex PCR with 18 different Y-chromosome-specific STS primer sets, spanning the AZFa, AZFb, AZFd, and AZFc regions. Detection of the same locus deletion of the AZFd region in three cases indicated the possible importance of the genes located in this region in spermatogenesis.
