Identificação de genes candidatos ao desenvolvimento de Leiomiomas Uterinos

Uterine leiomyomas (UL) are benign smooth muscle tumors from myometrium, representing the major indication for hysterectomies and a significant public health problem. Several genetics alterations have been associated with its development and pathogenesis. Although the initial factors that lead to the development of uterine leiomyomas are unclear, there are several evidences showing that ovarian steroids, estrogen and progesterone, are associated with these tumors.Recent reports, however, show others genes related with distinct signalization pathways besides sex hormones, which may be or not activated by these hormones, are associated with uterine leiomyomas development. In this study, the AHR, ESR1, ESR2, PGR and WNT7A gene transcripts expression was evaluated using quantitative real time RT-PCR in 58 UL samples compared to five normal myometrium tissues to explore the hormonal molecular basis of these tumors and associate these expression pattern with clinical and pathological features. The present study showed AHR, ESR1, ESR2, PGR and WNT7A down expression in 60%, 43%, 52%, 60% e 40% of the tumors, respectively, and a significant AHR loss of expression compared with the controls samples (P=0.0130). The comparison between the genes expression values revealed a positive correlation between the AHR and ESR1 transcripts (P<0.0001; r=0.6911) and between the genes ESR1 and WNT7A (P<0.0001; r=0.5655). The expression pattern was compared with clinical and pathological features. The WNT7A gene presented a differential expression pattern between the proliferative and secretory phase of menstrual cycle (P=0.0373) and the AHR and ESR1 genes were differentially expressed between women in reproductive and menopause years (P=0.0267; P=0.0415, respectively). The ESR1 and WNT7A down regulation was statistically ...(Complete abstract click electronic access below)

De novo transcriptome assembly for a non-model species, the blood-sucking bug Triatoma brasiliensis, a vector of Chagas disease

High throughput sequencing (HTS) provides new research opportunities for work on non-model organisms, such as differential expression studies between populations exposed to different environmental conditions. However, such transcriptomic studies first require the production of a reference assembly. The choice of sampling procedure, sequencing strategy and assembly workflow is crucial. To develop a reliable reference transcriptome for Triatoma brasiliensis, the major Chagas disease vector in Northeastern Brazil, different de novo assembly protocols were generated using various datasets and software. Both 454 and Illumina sequencing technologies were applied on RNA extracted from antennae and mouthparts from single or pooled individuals. The 454 library yielded 278 Mb. Fifteen Illumina libraries were constructed and yielded nearly 360 million RNA-seq single reads and 46 million RNA-seq paired-end reads for nearly 45 Gb. For the 454 reads, we used three assemblers, Newbler, CAP3 and/or MIRA and for the Illumina reads, the Trinity assembler. Ten assembly workflows were compared using these programs separately or in combination. To compare the assemblies obtained, quantitative and qualitative criteria were used, including contig length, N50, contig number and the percentage of chimeric contigs. Completeness of the assemblies was estimated using the CEGMA pipeline. The best assembly (57,657 contigs, completeness of 80 %, < 1 % chimeric contigs) was a hybrid assembly leading to recommend the use of (1) a single individual with large representation of biological tissues, (2) merging both long reads and short paired-end Illumina reads, (3) several assemblers in order to combine the specific advantages of each.
