Project description:Garcinia oblongifolia Champ. ex Benth is rich in bioactive molecules with immense remedial qualities and has pharmaceutical potentials. In this study, we reported the complete chloroplast genome (cpDNA) of G. oblongifolia, which is 156,577 bp in length, including a large single copy region (LSC) of 85,393 bp, a small single copy region (SSC) of 17,064 bp, and a pair of inverted repeats (IR) regions of 27,060 bp inserted between LSC and SSC. 129 genes are encoded, including 83 protein-encoding genes, 8 ribosomal RNA genes, and 36 transfer RNA genes. The overall GC content of the chloroplast genome is 36.2%, wherein the corresponding values in the LSC, SSC and IR regions are 33.6%, 30.3%, and 42.2%, respectively. Phylogenetic analysis showed that G. oblongifolia is sister to G. gummi-gutta with strong bootstrap support.
Project description:This study was conducted to appraise the protective effect of Indigofera oblongifolia leaf extract on lead acetate (PbAc)-induced nephrotoxicity in rats. PbAc was intraperitoneally injected at a dose of 20 mg/kg body weight for 5 days, either alone or together with the methanol extract of I. oblongifolia (100 mg/kg). Kidney lead (Pb) concentration; oxidative stress markers including lipid peroxidation, nitrite/nitrate, and glutathione (GSH); and antioxidant enzyme activities, namely superoxide dismutase, catalase, GSH peroxidase, and GSH reductase were all determined. The PbAc injection elicited a marked elevation in Pb concentration, lipid peroxidation, and nitrite/nitrate, with a concomitant depletion in GSH content compared with the control and a remarkable decrease in antioxidant enzymes. Oxidant/antioxidant imbalance, Pb accumulation, and histological changes in the kidneys were successfully prevented by the pre-administration of I. oblongifolia extract. In addition, the elevated expression of proapoptotic protein, Bax, in the kidneys of the PbAc-injected rats was reduced as a result of I. oblongifolia pre-administration, while the hitherto reduced expression of the anti-apoptotic protein Bcl-2 was elevated. Based on the current findings, it can be concluded that I. oblongifolia successfully minimizes the deleterious effects in kidney function and histological coherence associated with nephrotoxicity by strengthening the antioxidant defense system, suppressing oxidative stress, and mitigating apoptosis.
