solanum commersonii/phosphatase

The effects of vitamin D3 and the aqueous extract of Solanum malacoxylon on intestinal alkaline phosphatase and tissue phosphate content were studied on rachitic chicks treated with large doses of ethane-1-hydroxy-1,1 diphosphonate (EHDP). The EHDP treatment blocks the increase of intestinal calcium

OBJECTIVE Protein tyrosine phosphatase 1B (PTP 1B) and dipeptidyl peptidase IV (DPP IV) have been identified as one of the drug targets for the treatment of Type-2 diabetes. This study was designed to screen for PTP 1B and DPP-IV inhibitors from some Nigerian medicinal plants. METHODS PTP 1B and

1. Acid phosphatase (AcPase) from potato tubers was purified by tannic acid fractionation, DEAE-cellulose chromatography, filtration on Bio-Gel P-150 and affinity chromatography on Con A-Sepharose. The enzyme was purified 260-fold and was electrophoretically homogeneous; its mol. mass is about 69

Tuber formation in potato (Solanum tuberosum L.) is regulated by hormonal and environmental signals that are thought to be integrated in the leaves. The molecular mechanisms that mediate the responses to tuberization-related signals in leaves remain largely unknown. In this study we analyzed the

UNASSIGNED This study provides the first genetic evidence for the role of PP2A in tuberization, demonstrating that the catalytic subunit StPP2Ac2b positively modulates tuber induction, and that its function is related to the regulation of gibberellic acid metabolism. The results contribute to a

The nucleotide and amino acids sequences for AP(1) will appear in the GenBank(R) and NCBI databases under accession number AY297449. A novel antimicrobial protein (AP(1)) was purified from leaves of the potato ( Solanum tuberosum, variety MS-42.3) with a procedure involving ammonium sulphate

Genetic bases of isozyme phenotypes of alkaline phosphatase (AKP) and glucosephosphate isomerase (GpI) from tuber extracts of potato species of the genus Solanum were investigated by starch gel electrophoresis. Data were obtained from reciprocal F1 matings of S. tuberosum X ssp. andigena (Juz. &

Salinity stress limited the production in over 30% of irrigated crops and 7% of dryland agriculture worldwide. The objective was to evaluate the effects of NaCl-stress on the enzymatic activity in tomato. Two experiments were carried out in germination and early vegetative growth stages. The

Storage of potato tubers at low temperatures leads to the accumulation of glucose and fructose in a process called 'cold sweetening'. The aim of this work was to investigate the role of sucrose-phosphatase (SPP) in potato tuber carbohydrate metabolism at low temperature (4 degrees C). To this end,

Potato (Solanum tuberosum) plants susceptible to late blight disease caused by the oomycete Phytophthora infestans display enhanced resistance upon infiltration with the pathogen-associated molecular pattern (PAMP), Pep-13. Here, we characterize a potato gene similar to Arabidopsis 5-phosphatases

Protein phosphorylation/dephosphorylation plays critical roles in stress responses in plants. This report presents a comparative characterization of the serine/threonine PP2A catalytic subunit family in Solanum tuberosum (potato) and S. lycopersicum (tomato), two important food crops of the

The present work is aimed to investigate the toxicity of 1/20 LD50 of cadmium chloride (CdCl2) on male albino rats by oral ingestion and to determine the hepatoprotective effect of Solanum nigrum Linn (SN) dried fruits and their ethanolic extract against CdCl2 toxicity using biochemical parameters.

Wistar albino female rats were maintained for 10 d on diets containing various levels of the vegetable Solanum nigrum. Simultaneously, they received daily intraperitoneal injections of aflatoxin B1 (AFB1) (either 0.2 or 0.4 mg/kg body-weight) diluted in propylene glycol. At the end of the

Replacement of the drinking water of chicks maintained on a normal mixed protein diet with an aqueous extract containing the equivalent of 5 g of the dried leaves of Solanum malacoxylon (DLSM) per 100 ml for one month produces a hypercalcaemia (23-49 per cent), hypomagnesamia (28-37 per cent),

1. Administration of an aqueous extract of the dried leaves of Solanum malacoxylon (DLSM) to rats causes a rapid hyperphosphataemia and a decrease in plasma alkaline phosphatase activity; the two effects are typical of 1,25(OH)2D3, the hormonally active metabolite of vitamin D3. 2. DLSM, like both
