OBJECTIVE: The present study seeks to determine the mutation spectrum of the AGL gene in Malaysian population.
METHODS: A total of eleven patients (eight Malay, two Chinese and one Bajau) were investigated. Genomic DNA was extracted and subsequently the AGL gene was amplified using specific primers and sequenced. Mutations found were screened in 150 healthy control samples either by restriction enzyme digestion assay or TaqMan® SNP Genotyping assay.
RESULTS: We identified six unreported mutations (c.1423+1G>T, c.2914_2915delAA, c.3814_3815delAG, c.4333T>G, c.4490G>A, c.4531_4534delTGTC) along with three previously reported mutations (c.99C>T, c.1783C>T, c.2681+1G>A). One of the six unreported mutation causes abnormal splicing and results in retention of intron 12 of the mature transcript, while another is a termination read-through. One of the reported mutation c.2681+1G>A was recurrently found in the Malay patients (n = 7 alleles; 31.8%).
CONCLUSION: The mutation spectrum of the AGL gene in Malaysian patients has shown considerable heterogeneity, and all unreported mutations were absent in all 150 healthy control samples tested.
OBJECTIVE(S): The effects of tamarind seeds (T) on lipid and carbohydrate metabolism in rats were studied. Rats were offered basal diet (BD) with T (2%, 4% or 8%) or without T.
MATERIALS AND METHODS: Feeding and growth performance in rats were measured and samples of liver and blood were analyzed for glycogen content and levels of cholesterol and glucose respectively.
RESULTS: The inclusion of T in the diet influences the feeding and growth performance in rats. The serum cholesterol level was reduced (p glycogen storage in livers of SD rats fed on BD and high sucrose diet.
CONCLUSION: Tamarind seeds can lower blood glucose and serum cholesterol and enhance storage of glycogen in rats.
