Neddylation is a posttranslational modification that plays important roles in regulating protein structure and function by covalently conjugating NEDD8, an ubiquitin-like small molecule, to the substrate. Here, we report that Parkinson's disease (PD)-related parkin and PINK1 are NEDD8 conjugated. Neddylation of parkin and PINK1 results in increased E3 ligase activity of parkin and selective stabilization of the 55 kDa PINK1 fragment. Expression of dAPP-BP1, a NEDD8 activation enzyme subunit, in Drosophila suppresses abnormalities induced by dPINK1 RNAi. PD neurotoxin MPP(+) inhibits neddylation of both parkin and PINK1. NEDD8 immunoreactivity is associated with Lewy bodies in midbrain dopaminergic neurons of PD patients. Together, these results suggest that parkin and PINK1 are regulated by neddylation and that impaired NEDD8 modification of these proteins likely contributes to PD pathogenesis. 相似文献

Systemic endemic mycoses, such as blastomycosis, are rare in Asia and have been reported as health risks among travelers who visit or reside in an endemic area. Adrenal involvement is rarely seen in blastomycosis and has never been reported from Asia. We report the first case of blastomycosis with bilateral involvement of the adrenals in a diabetic patient residing in the state of Arunachal Pradesh, India. 相似文献

Trichoadenoma of Nikolowski is a rare benign cutaneous tumor, which is usually solitary, nodular and occurs on the face or buttocks any time during adult life. The morphological differentiation of trichoadenoma is situated between a trichofolliculoma and a trichoepithelioma with hair follicle-like direction of differentiation. We report this case of trichoadenoma in a 28-year-old man who presented with a solitary nodular and ulcerated swelling in the gluteal region, gradually increasing in size. Excision biopsy revealed characteristic features consistent with trichoadenoma. We report this case in view of its rarity. 相似文献

Hilmilin (diflubenzuron), an insect growth regulator, was tested for efficacy against Anopheles stephensi, Anopheles culicifacies, Aedes aegypti, and Culex quinquefasciatus in the laboratory and in field conditions. Fifty percent and 90% lethal concentrations (LC50 and LC90) of Hilmilin formulations were determined by exposing early 4th-stage larvae to serial dilutions of the formulation, and data were subjected to log probit analysis. Two doses (0.004 and 0.008 g/m2) were applied in different breeding habitats of mosquitoes with the help of stirrup pumps. Percent inhibition of adult emergence was compared according to a previously described procedure. Laboratory results revealed that both 25WP (wettable powder) and 22SL (semiliquid) formulations showed more or less the same degree of efficacy against tested mosquito species (P < 0.05). Of 4 species tested, An. stephensi was more susceptible, followed by An. culicifacies, Ae. aegypti, and Cx. quinquefasciatus. One hundred percent inhibition of adult emergence was observed at a dose of 0.0125 ppm (25WP and 22SL) against all mosquitoes tested in the laboratory. Both formulations showed almost similar effect when applied in the field at doses of 0.004 and 0.008 g/m2 in their respective preferential breeding habitats. However, the effect was more pronounced at a higher concentration (0.008 g/m2) against all species of mosquitoes. Hilmilin at a dose of 0.008 g/m2 can be used to contain mosquito breeding in stone quarries, pools, cement tanks, unused wells, unused coolers, and irrigation channels. 相似文献
