Overview: This is translational bioinformatics was focused on analysis of single nucleotide polymorphism of FBN1 gene and reviewing of the previous citations of the damaging SNPs. Introduction: Marfan syndrome is a common autosomal dominant hereditary connective tissue disorder with variable presentations, mutations in FBN1 gene were found to be responsible for Marfan syndrome and other related connective tissue disorders, SNPs contributes to gene mutations and expression variations justifying phenotypic variations among patients and hence such SNPs would be potential target for identification and analysis which may help in early diagnosis of such life threatening disorder. Methods: computational methods were used on this work focusing on analysis of SNPs in the coding regions of FBN1 gene found as non-synonymous variants (ns-SNP) and those in the 3’un-translated regions (3’UTR) affecting miRNA binding using computational methods including SIFT and polyphen for analysis of (nsSNPs), prediction of not previously described SNPs was done using project hope software, while (3’UTR) SNPs was analyzed using PolymiRTS tool functions interactions of FBN1 gene with functionally similar gene were predicted using Genemania software. Results: Out of 1134 ns-SNPs analyzed 38 SNPs were found to damaging while analysis of 175 SNP in 3’UTR prove that 24 SNPs are disturbing to their target sites and 46 SNPs are creating to new target sites.On reviewing of previous citation 31 of the predicted damaging nSNPs were reported as mutations with specific Marfan syndrome presentation while 6 nsSNP were not previously reported with high damaging probability.

Aims: Nauclea latifolia Sm. (Rubiaceae) is known for its therapeutic uses, especially in alternative medicine. Its leaves, roots and bark have been used traditionally in Nigeria to treat various diseases including ulcer-related diseases. Methods: The aqueous stem bark extract of Nauclea latifolia was investigated for anti-ulcerogenic effects using ethanol/HCI and indomethacin as the ulcerogens. The effect of the extract on gastric mucous secretion was also investigated. The extract was administered orally at the doses of 100 and 200 mg/kg b. wt. for the experimental groups while the control and reference groups received distilled water (2 ml/kg, p.o) and omeprazole (20 mg/kg, p.o) respectively. Results: Phytochemical studies revealed the presence of saponins, tannins, alkaloids, terpenes and glycosides. The results show that the extract significantly (p < 0.05) reduced the ulcer index from 4.55 ± 1.45 to 1.20 ± 0.19 and from 4.20 ± 0.72 to 0.94 ± 2.51 in the ethanol/HCI and indomethacin induced ulceration respectively. The extract also significantly (p < 0.05) increased the gastric mucous secretion in a dose-dependent manner. Conclusions: The results suggest that the N. latifolia stem bark extract possesses significant anti-ulcer effects which might be due to its ability to increase gastric mucous secretion.

The effects of selenium on healing of acetic acid induced gastric ulcer investigated in albino Wistar rats and the results were compared with that of a standard drug omeprazole. Animals were anesthetized with 50mg/kg sodium thiopental, laparotomy was performed and gastric ulcer was induced by application of 80% acetic acid to the serosal surface of stomach. Animals were then divided into three groups. Group 1 was treated with 1 ml/kg/day normal saline (NS) (p.o), group 2; 100µg/kg/day selenium (p.o) and group 3; 20mg/kg/day omeprazole (p.o). Treatment period was 10 days post ulcer induction. Assessment of ulcer healing was done on days 3, 7 and 10 respectively by measurement of ulcer area, lipid peroxidation, catalase activity and mucus secretion. Result showed that by day 7 and 10, the reduction in ulcer area was more significant in selenium and omeprazole treated (p< 0.05, 0.05) respectively. By day 7 and 10, lipid peroxidation was significantly lower in selenium and omeprazole treated as compared with NS treated (p<0.05, 0.05). Furthermore by day 3, 7 and 10, catalase activity was significantly higher (p < 0.05) in selenium treated as compared with NS treated. Result also showed that mucus secretion was significantly higher in selenium and omeprazole treated (p < 0.001, 0.001) compared with NS by day 7. However, by day 10, secretion in both selenium and omeprazole treated had started to decline. In conclusion, selenium accelerated ulcer healing by facilitating mucosal regeneration, reducing lipid peroxidation, increasing antioxidant activity and by altering mucus secretion response.
