In this study, the existence of vasculogenic mimicry (VM) in cervical squamous cell carcinoma was investigated. To this end, the relationship between hypoxia-inducible factor 1α (HIF-1α) and the development, infiltration, and metastasis of cervical squamous cell carcinoma was studied. Between January 2010 and December 2010, 67 human cervical squamous carcinoma tissue samples were ... more
Vimentin is a cytoskeletal protein belonging to a family of intermediate filaments whose expression has been studied in human cancers due to its association with the mesenchymal epithelial transition, a cancer reactivation event that results in complex alterations in the expression of genes involved in the invasion and metastasis processes. Studies on the ... more
Nasopharyngeal carcinoma (NPC) is a rare cancer in the Western hemisphere (1 case per 100,000 individuals). Conversely there are some areas, such as Southern China, Southeast Asia (Vietnam), the Mediterranean basin and Alaska, where morbidity reaches 80 per 100,000 individuals. Detecting cervical lymph node metastasis is important because it helps recommend the ... more
Epilepsy is one of the most frequent neurological disorders. Recently, the regulation of microRNAs was found to be associated with epilepsy, but the molecular mechanism by which microRNA influences epilepsy process remains to be unveiled and the development of microRNA-based therapy requires more intensive research. In this study, five microRNAs with potential relevance to epilepsy were ... more
Hypoxia influences many physiological processes, such as respiration, cardiovascular, neurophysiology, and digestion. Skeletal muscle is an important motor organ, which relies on oxygen of oxidation; however, the study of hypoxia in skeletal muscle is lacking. In order to understand the effect of hypoxia on skeletal muscle, we determined the expression level of four hypoxia-related genes ( ... more
Skeletal muscle growth is regulated by both positive and negative factors, such as myogenic regulatory factors (MRFs) and myostatin (MSTN), and involves both hyperplasia and hypertrophy. In the present study, morphological changes during muscle development in Megalobrama amblycephala were characterized and gene expression levels were measured by quantitative real-time polymerase chain ... more
The present study was conducted to evaluate the responses of three annual Medicago species (M. truncatula, M. laciniata, and M. polymorpha) to salinity. We analyzed publicly available microarray data in NCBI pertaining to salinity-response genes in M. truncatula. Our data search identified Tubby C2 (TLP) and ethylene responsive ... more
Excess Leu reduces the availability of Ile and Val in pigs likely by reducing absorption of the latter amino acids (AA). Twenty-four crossbred pigs were used to evaluate the effect of excess Leu alone or with surplus Ile and Val on the expression of cationic (b0,+AT and CAT1) and neutral (B0AT1) AA transporters in the small intestine, liver, and skeletal ... more
Red-fleshed oranges (Citrus sinensis) contain high levels of carotenoids and lycopene. The growing consumer demand for products with health benefits has increased interest in these types of Citrus cultivars as a potential source of nutraceuticals. However, little is known about the physiology of these cultivars under Brazilian conditions. Transcriptome and gene ... more
Based on gene expression, we have classified 53 colon cancer patients with UICC II into two groups: relapse and no relapse. Samples were taken from each patient, and gene information was extracted. Of the 53 samples examined, 500 genes were considered proper through analyses by S-Kohonen, BP, and SVM neural networks. Classification accuracy obtained by S-Kohonen neural network reaches 91 ... more
