“The precise causes of psoriasis, a chronic skin disorder characterized by hyperproliferation of keratinocytes and incomplete keratinization, are
unclear. It is known that expression of helix-loop-helix transcription factor Id1, which functions as an inhibitor of differentiation, is upregulated in psoriatic skin. We investigated the effect of the antipsoriatic drug dithranol on mRNA and protein expression levels of Id1 in the HaCaT keratinocyte cell line. Cultured HaCaT cells were treated with 0-0.5 mu g/mL dithranol for 30 min. After 2 and 4 h, total cellular RNA and total proteins were isolated from HaCaT cells, and quantitative real-time reverse transcriptase selleck products (RT-PCR) and Western blot were used to determine the mRNA and protein levels of Id1, respectively. Changes in normalized Id1 mRNA levels were observed only after 4 h of
Fedratinib molecular weight dithranol treatment. There was reduced expression of Id1 mRNA transcripts in the HaCaT cells treated with 0.1 mu g/mL dithranol, but the reduction was not significant. The expression of Id1 mRNA was significantly downregulated (almost 50%) when 0.25 or 0.5 mu g/mL dithranol was applied to the HaCaT cells. However, the normalized Id1 protein levels were not significantly affected. The molecular mechanisms underlying this finding should be investigated further to help determine
the therapeutic action of this drug.”
“Bisphosphonate treatment for bone fragility has expanded beyond children with osteogenesis imperfecta (OI) to those with other causes of low bone mass. However, clinical efficacy and optimal dosing in non-OI patients has not been established. We conducted a retrospective descriptive study of patients with non-OI-related bone fragility to describe the effects of two different pamidronate treatment regimens on the bone mineral density (BMD) and fracture rate of these children. Between 2000 and 2009, 15 non-OI patients aged find protocol 8-16 years received pamidronate 1 mg/kg intravenously for 1 day every 3 months (4 mg/kg/year) or 1 mg/kg/day for 3 days every 4 months (9 mg/kg/year). After 1 year of pamidronate, the two groups had a comparable increase in adjusted BMD and reduction in fragility fractures. No serious adverse effects were observed. Since the long-term effects of bisphosphonate are unknown, large trials are needed to delineate the minimal effective dose in these patients.”
“Finding an efficient and affordable treatment against malaria is still a challenge for medicine. Artemisinin is an effective antimalarial drug isolated from Artemisia annua. However, the artemisinin content of A. annua is very low. We used transgenic technology to increase the artemisinin content of A.
