Polymorphisms of the GSTT1 and GSTM1 genes in polycystic ovary syndrome

SUMMARY BACKGROUND: This study aimed to investigate the deletion polymorphisms of the genes of the glutathione S-transferase family GSTT1 and GSTM1 in patients with Polycystic Ovarian Syndrome (PCOS), comparing them with a control population. METHODS: Blood was collected from 219 women (110 with PCOS a...

Análise comparativa do polimorfismo genético da glutationa transferase, do Helicobacter pylori e do vírus Epstein-Barr entre a área do tumor e as margens de ressecção proximal e distal do câncer gástrico

Rev. Col. Bras. Cir; 46 (1), 2019
RESUMO Objetivo: comparar o polimorfismo dos genes Glutationa S-transferase teta 1 (GSTT1) e Glutationa S-transferase mu 1 (GSTM1) da área do tumor com as margens proximal e distal de espécimes de estômago ressecados de pacientes com câncer gástrico, e investigar a presença do DNA do vírus Epstei...

Avaliação genética nos diferentes fenótipos da Doença Pulmonar Obstrutiva Crônica
Genetic evaluation of the different phenotypes of Chronic Obstructive Pulmonary Disease

A doença pulmonar obstrutiva crônica (DPOC) caracteriza-se por apresentação heterogênea e, recentemente, tem-se tentado subdividir os pacientes em diferentes fenótipos, sendo os principais: Exacerbador, Misto DPOC-asma e Enfisema hiperinsuflador. Diversos genes têm sido avaliados quanto à possív...

A study of the association of glutathione S-transferase M1/T1 polymorphisms with susceptibility to vitiligo in Egyptian patients

An. bras. dermatol; 93 (1), 2018
Abstract: Background: The association of glutathione S-transferases M1/T1 (GSTM1/T1) null polymorphisms with vitiligo was proposed in several studies including two Egyptian studies with contradictory results. Objective: The aim here was to assess the association between GSTM1/T1 null polymorphisms and ...

CYP1A1, CYP1B1, GSTM1 and GSTT1 genetic variants and breast cancer risk in Mexican women

Salud pública Méx; 59 (5), 2017
Abstract: Objective: To evaluate if variants in the genes CYP1A1 (T3801C and A4889G), CYP1B1 (G119T), GSTM1 (indel) and GSTT1 (indel) are associated with breast cancer (BC) among Mexican women. Materials and methods: 952 incident cases with histologically confirmed BC were matched by age (± 5 years)...

Genotype association gstm1 null and gastric cancer: evidence-based meta-analysis

Arq. gastroenterol; 54 (2), 2017
ABSTRACT BACKGROUND Gastric cancer is the fourth most common cancer in men and the sixth among women, except for non-melanoma skin tumors, in Brazil. Epidemiological evidences reveal the multifactorial etiology of this cancer, highlighting risk factors such as: infection by the bacterium Helicobacter p...

Frecuencia de los polimorfismos CYP1A1*2A y deleción del gen GSTM1 en pacientes con carcinoma de células escamosas de laringe en relación al hábito tabáquico: estudio piloto en Chile

Introducción: Entre los factores de riesgo para cáncer laríngeo (CL) son relevantes el consumo de tabaco y alcohol. Estos xenobióticos son metabolizados por un grupo de enzimas, entre las cuales están CYP1A1 y GSTM1, cuyas variantes polimórficas se postulan como factores de riesgo para esta enferme...
