Detection of Retinoic Acid Receptor Complex using Mass Spectrometry
نویسندگان
چکیده
O receptor de ácido retinóico é um fator de transcrição no núcleo celular que se liga ao ácido retinóico. A esfera de atuação do ligante do receptor gama do ácido retinóico humano (seu complexo com ácido retinóico e sua interação com a proteína I ácido retinóico ligante) foi estudada por espectroscopia de massa. O caminho do ácido retinóico a partir do doador até o receptor foi monitorado on-line. Não foi observado nenhum complexo terciário envolvendo ácido retinóico e as duas proteínas, indicando que o transporte do ácido retinóico a partir da proteína ligante I até seu receptor poder seguir um mecanismo de dois passos, que envolve a dissociação do ácido retinóico a partir de sua proteína em fase aquosa, seguida de associação ao aceptor.

Retinoic acid receptor alpha is associated with tamoxifen resistance in breast cancer
About one-third of oestrogen receptor alpha-positive breast cancer patients treated with tamoxifen relapse. Here we identify the nuclear receptor retinoic acid receptor alpha as a marker of tamoxifen resistance. Using quantitative mass spectrometry-based proteomics, we show that retinoic acid receptor alpha protein networks and levels differ in a tamoxifen-sensitive (MCF7) and a tamoxifen-resis...
متن کاملHPLC-MS/MS analysis of the products generated from all-trans-retinoic acid using recombinant human CYP26A.
Two mammalian hCYP26A expression systems have been used to analyze the metabolic products of CYP26A. Through the use of extensive HPLC, UV spectroscopy, and liquid chromatography/tandem mass spectrometry (LC-MS/MS) methodology, we have conclusively demonstrated that the complex mixture of products comprises 4-OH-all-trans-retinoic acid, 4-oxo-all-trans-retinoic acid, and 18-OH-all-trans-retinoi...

Retinoic Acid Receptor Responder (RARRES1) initially identified as a novel retinoic acid receptor regulated gene in the skin is a putative tumor suppressor of unknown function. RARRES1 was knocked down in immortalized human prostatic epithelial cell line PWR-1E cells and differential protein expression was identified using differential in-gel electrophoresis (DIGE) followed by matrix-assisted l...

A selective and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the determination of berberine, palmatine and jatrorrhizine in rat plasma. Target compounds, together with the internal standard (metronidazole), were extracted from rat plasma samples by protein precipitation with acetonitrile-methanol (1:2, v/v). Chromatography was carried out using a ...

A rapid and sensitive liquid chromatography–tandem mass spectrometry (LC-MS) method was developed for the determination of enalapril and enalaprilat in human plasma. Detection of analytes was achieved by tandem mass spectrometry with electrospray ionization (ESI) interface in positive ion mode which was operated under the multiple-reaction monitoring mode. Sample pretreatment was involved...
