Resumo: A fissura labial e/ou palatina (FL/P) não-sindrômica é uma malformação congênita do lábio e/ou palato com alta frequência na população brasileira. A etiologia das fissuras é complexa e conta com a participação de fatores genéticos e ambientais. Inúmeros estudos demonstraram que variantes polimórficas das enzimas relacionadas ao metabolismo do ácido fólico podem ser importantes fatores de risco materno para o nascimento de uma criança FL/P não-sindrômica. O objetivo deste estudo foi estudar a influência do consumo de suplementos vitamínicos durante o primeiro trimestre de gravidez e comparar a frequência alélica e genotípica de 4 genes (MTHFR, MTHFD1, MTR e RFC1) que codificam enzimas da via metabólica do ácido fólico entre mães de indivíduos portadores de FL/P não-sindrômicas (grupo experimental) e mães de indivíduos clinicamente normais (grupo controle). Amostras de DNA de 184 mães do grupo controle e de 106 mães do grupo experimental foram genotipadas por reação em cadeia da polimerase associada à análise de polimorfismo de fragmentos de restrição enzimática (PCR-RFLP). A ausência de suplemento vitamínico durante o primeiro trimestre de gravidez aumentou de forma discreta (aproximadamente em 0,4 vezes) o risco de uma mulher ter um filho com FL/P não-sindrômica. Dos 15 polimorfismos analisados neste estudo, 2 apresentaram diferenças entre os grupos. No polimorfismo rs2274976 do gene MTHFR, o alelo A e o genótipo GA ocorreram em uma frequência significantemente maior no grupo experimental que no grupo controle (p<0,000001), aumentando em aproximadamente 6 vezes o risco de uma mãe ter um filho com FL/P não-sindrômica. O genótipo AA no lócus polimórfico rs2236225 do gene MTHFD1 foi significantemente mais prevalente no grupo experimental comparado com o grupo controle (p=0,02). A presença deste genótipo aumentou em aproximadamente 2 vezes o risco de uma mãe ter um filho com FL/P não-sindrômica. Análise multivariada demonstrou que estes fatores contribuíram de maneira independente para a etiologia das FL/P não-sindrômicas. O presente estudo demonstra que os polimorfismos rs2274976 do gene MTHFR e rs2236225 do gene MTHFD1 e a suplementação vitamínica durante o primeiro trimestre de gravidez estão associados ao desenvolvimento de FL/P não-sindrômicas na população brasileira. Este estudo corrobora com evidências prévias que demonstraram a influência de fatores ambientais e genéticos na etiopatogenia das FL/P não-sindrômicas.
Abstract: Nonsyndromic cleft lip with or without cleft palate (CL/P) is a congenital malformation of the lip and/or palate with elevating frequency in the Brazilian population. The etiology of the nonsyndromic CL/P is complex and both environmental and genetic factors play important roles. Several studies demonstrated that polymorphisms in the folic acid metabolic enzymes may be important maternal risk factor for the birth of a child with nonsyndromic CL/P. The aim of this study was to determine the influence of the multivitamin supplements during the first trimester of pregnancy and to compare the allele and genotypic frequencies of 4 genes (MTHFR, MTHFD1, MTR and RFC1) that encode enzymes of the acid folic metabolic pathway between mothers of nonsyndromic CL/P patients (experimental group) and mothers of clinically normal children (control group). DNA samples from 184 mothers of the control group and from 106 mothers of the experimental group were genotyped by polymerase chain reaction associated with reaction fragment length polymorphism (PCR-RFLP). The lack of multivitamin supplementation during the pregnancy first trimester increased in approximately 0.4-fold the maternal risk of a nonsyndromic CL/P child. Two out of 15 polymorphisms showed differences between groups. In rs2274976 MTHFR polymorphism, allele A and genotype GA occurred in a significantly higher frequency on experimental group when compared to control group (p<0.000001), rising in approximately 6 times the risk of a mother giving birth to a nonsyndromic CL/P child. Genotype AA in the rs2236225 MTHFD1 polymorphic locus was significantly more prevalent in experimental group than in control group (p=0.02). This genotype raised in approximately twice the risk of a mother giving birth to a nonsyndromic CL/P child. Multivariate analysis demonstrated that those factors contributed in an independent manner to nonsyndromic CL/P etiology. The present study shows that rs2274976 MTHFR and rs2236225 MTHFD1 polymorphisms, as well as the multivitamin supplementation during the first trimester of pregnancy, are associated with the development of nonsyndromic CL/P in the Brazilian population. This study corroborates with previous evidences demonstrating the influence of environmental and genetic factor on etiopathogenesis of the nonsyndromic CL/P.

Повний текст джерелаThe more common and mild deficiency observed in the general healthy population is probably due in part to insufficient dietary intake of folate. Folate deficiency has been associated with increased risk for colon cancer. In a pilot study presented here, the impact of altered folate intake on tumor multiplicity in the Min mouse, a model for multiple intestinal neoplasia, was assessed. Folate deficient diets did not produce a consistent change in tumor numbers. However, a linear correlation between S-adenosylmethionine and S-adenosylhomocysteine content of preneoplastic tissue and tumor multiplicity was identified.
This thesis contributes to our understanding of the impact of genetic- and/or dietary-induced folate deficiency on cellular and organismal functions.

Повний текст джерелаThe reduced folate carrier I (RFC1) is responsible for the cellular uptake and intestinal absorption of folate, primarily the 5-methyltetrahydrofolate (5-methylTHF) derivative. Methionine synthase (MTR) uses 5-methylTHF to remethylate homocysteine to methionine, which may be activated and used to methylate substrates such as DNA. 5-MethylTHF is also the product of the methylenetetrahydrofolate reductase (MTHFR)-catalysed reduction of 5,10-methyleneTHF, which is also used to convert dUMP to dTMP.
Adenoma number and load were reduced in Rfc1+/-Apc min/+ mice, compared with Rfc1+/+Apc min/+ mice, but were similar in Mtr+/-Apc min/+ and Mtr+/+ Apcmin/+ mice. Neither Rfc1 nor Mtr genotype affected global DNA methylation, apoptosis or plasma homocysteine (tHcy) levels. In the experiments involving Mtr mice, dietary folate deficiency increased adenoma number, plasma tHcy, and apoptosis, and decreased global DNA methylation. Neither Mtr nor Rfc1 genotype affected the dUTP/dTTP ratio in the intestine of mice not predisposed to adenoma formation.
Adenoma number was decreased in Mthfr+/-Apc min/+ mice (compared with Mthfr+/+Apc min/+ mice) and in Mthfr+/+Apc min/+ offspring of Mthfr+/- mothers (compared with Mthfr+/+Apcmin/+ offspring of Mthfr+/+ mothers). A folate-deficient diet, when initiated prior to conception, significantly decreased adenoma number and decreased global DNA methylation. Overall, adenoma number was inversely correlated with plasma tHcy, dUTP/dTTP ratio and apoptosis. When initiated at three weeks of age, a folate-enriched diet significantly increased adenoma number in Apcmin/+ mice. In the intestines of mice not predisposed to adenoma formation, Mthfr deficiency decreased, and folic acid deficiency increased, the dUTP/dTTP ratio.
These results support the evidence that MTHFR polymorphisms are protective in CRC tumourigenesis and that depending on stage or predisposition, folate may inhibit or enhance tumour growth.
