Since molecular phylogenies of stichotrich ciliates started to be published, some remarkable contradictions to morphology- based classifications have been reported, such as the Convergent Evolution of Urostylids and Uroleptids (CEUU) hyphothesis, the Halteria paradox, the polyphyly of Oxytricha and of Stichotrichia. We hypothe.. Read More»

Both BMP2 and BMP4 are involved in tooth development. We examined phenotypes and BMP2 and BMP4 gene variations in two Mexican oligodontia families. Physical and oral examinations and panoramic radiographs were performed on affected and unaffected members in these two families. The affected members lacked six or more teeth. DNA sequencing was performed to .. Read More»

Nucleotide excision repair (NER) acts on a broad spectrum of large lesions, while base excision repair removes individual modified bases. Although both processes have been well studied in human cells, novel genes involved in these DNA repair pathways have been described. Using a heterologous complementation approach, we identi..

Estrogen receptor-a (ER) protein plays a key role in breast carcinogenesis, and common genetic variants in the corresponding gene locus have been associated with breast cancer risk in different populations. Here, we analyzed estrogen receptor 1 (ESR1) associations in two hospital-based studies of patients from the south of China. Three single-nucleotide p.. Read More»

We investigated the influence of the c.1517G>C genetic variant in the X-ray repair complementing group 1 gene (XRCC1) on pancreatic cancer (PC) susceptibility in Chinese patients. A total of 390 PC patients and 392 controls were enrolled in this case-control study. The genotypes of c.1517G>C genetic variants were determi.. Read More»

Spondyloepiphyseal dysplasia (SED) is an autosomal dominant skeletal dysplasia characterized by short stature, abnormal epiphyses and flattened vertebral bodies. SED is mainly caused by mutations in the gene encoding the type II procollagen Ã?±-1 chain (COL2A1). We looked for mutations in COL2A1 in three unrelated Chinese families with SED. Putative mutatio..

The Canchim (5/8 Charolais + 3/8 Zebu) beef cattle breed was developed at Southeast-Embrapa Cattle to take advantage of hybrid vigor and to combine the higher growth rate and beef quality of Charolais with tropical adaptations of Zebu. The development of three lineages (old, new, and crossbred) has increased its genetic basis... Read More»

Diabetic retinopathy (DR), an important complication of diabetes mellitus (DM), is not well understood. T helper cell balance (Th1/Th2) is involved in various autoimmune diseases; however, its role in DR is not understood. This study explores changes in Th1 and Th2 cytokine expression during DR. Blood samples were collected from 25 healthy volunteers (nor.. Read More»

A previous study has revealed that miR-29c functions as a tumor suppressor in hepatocellular carcinoma (HCC), but the clinical significance and prognostic value of miR-29c in HCC have not been investigated. Paired human HCC tissues and adjacent noncancerous tissues were obtained from 91 patients, between 2008 to 2014. Quantitative real-time PCR (qRT-PCR) .. Read More»
