objective(s): the aim of this study was to investigate the methylation status and mrna expression levels of p15, death-associated protein kinase (dapk), and suppressor of cytokine signaling-1 (socs1) genes in multiple myeloma (mm). materials and methods: the bone marrow samples of 54 mm patients were collected and the methylation status of the p15, dapk, and socs1 gene promoter regions was dete...

conclusions some results of the correlation coefficients are not the same with visualization. the reason may be due to the small number of data. materials and methods in the foundation-application study, we constructed two-way gene networks using nonparametric methods, such as spearman’s rank correlation coefficient and blomqvist’s measure, and compared them with pearson’s correlation coefficie...

The reproductive mechanism of Giardia intestinalis, considered one of the earliest divergent eukaryotes, has not been fully defined yet. Some evidence supports the hypothesis that Giardia is an exclusively asexual organism with a clonal population structure. However, the high genetic variability, the variation in ploidy during its life cycle, the low heterozygosity and the existence of genes in...

Homologous recombination in meiosis is initiated by the programmed induction of double strand breaks (DSBs). Although the Drosophila Spo11 ortholog Mei-W68 is required for the induction of DSBs during meiotic prophase, only one other protein (Mei-P22) has been shown to be required for Mei-W68 to exert this function. We show here that the chromatin-associated protein Trade Embargo (Trem), a C2H2...

A fundamental question for meiosis is how homologous chromosomes (homologs) find each other and pair together to ensure homologous recombination and segregation. Intuitively, the answer to the question is related to the interaction between homologous sequences. However, that is not the whole story according to some studies on the role of cohesins in homolog pairing. The most recent one by Ishig...
