Long-wavelength sensitive opsin (LWS) gene variability in Neotropical cichlids (Teleostei: Cichlidae)

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT Cichlid fishes are an important group in evolutionary biology due to their fast speciation. This group depends widely of vision for feeding and reproduction. During the evolutionary process it plays a significant role in interspecific and intraspecific recognition and in its ecology. The molecul...

Lack of evidence of HPV etiology of prostate cancer following radical surgery and higher frequency of the Arg/Pro genotype in turkish men with prostate cancer

Int. braz. j. urol; 43 (1), 2017
ABSTRACT Objectives The aim of this study was to assess the possible role of HPV in the development of prostate cancer (PCa) and investigate the distribution of the p53 codon 72 polymorphism in PCa in a Turkish population.

Genetic alterations in Ki-ras and Ha-ras genes in juvenile nasopharyngeal angiofibromas and head and neck cancer

Säo Paulo med. j; 117 (3), 1999
Context: Ras gene mutations have been associated to a wide range of human solid tumors. Members of the ras gene family (Ki-ras, Ha-ras and N-ras) are structurally related and code for a protein (p21) known to play an important role in the regulation of normal signal transduction and cell growth. The freq...

Perda do sítio de restriçäo fok-I no codon 918 do proto-oncogenese RET na neoplasia endócrina múltipla tipo 2B
Fok-1 restriction site loss in codon 918 of RET proto-oncogene in type 2b multiple endocrine neoplasm

Descreveu-se o uso de método simplificado de detecção de perda do sítio de restrição que envolve o codon 918 do protooncogene RET, usando-se digestão direta com a enzima de restrição fok-I. Este método foi aplicado na análise do DNA genômico do sangue periférico de uma paciente com neoplasia...
