A TG microsatellite in the 3'-untranslated region (UTR) of FGF9 mRNA has previously been shown to modulate FGF9 expression. In the present study, we investigate the possible interacting protein that binds to FGF9 3'-UTR UG-repeat and study the mechanism underlying this protein-RNA interaction. We first applied RNA pull-down assays and LC-MS analysis to identify proteins associated with this rep...

BACKGROUND The CloneSelect Imager system is an image-based visualisation system for cell growth assessment. Traditionally cell proliferation is measured with the colorimetric MTT assay. RESULTS Here we show that both the CloneSelect Imager and the MTT approach result in comparable EC50 values when assaying the cytotoxicity of cisplatin and oxaliplatin on various cell lines. However, the image...

Abstract Background LncRNA HOXA-AS2 has been found in the literature to deteriorate glioblastoma. However, its regulatory mechanism is yet be fully investigated. Our study focused chiefly on interaction and role of HOXA-AS2/miR-885-5p/RBBP4 axis development Methods qRT-PCR analysis was performed detect expression lncRNA, miRNA mRNA glioblastoma tissues cells. Dual-luciferase assay, RIP assay RN...

The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, which measures the reduction of MTT, is commonly used to validate the viability of metabolically active cells. This study was conducted to evaluate and validate the MTT assay to assess the spermatozoal viability of Nili-Ravi buffalo bulls and compare the efficiency of the test with the supravital staining technique (e...

This paper describes a critical evaluation of a miniaturised colorimetric assay, using MTT (3-[4,5-dimethyl-thiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) reduction, applied to protozoan viability testing. The toxic substances used were copper, zinc, Triton X-100 (a membrane surfactant) and cycloheximide (an inhibitor of the protein synthesis). The viability assay of the ciliate protozoan Tetr...

The activation of the pleomorphic adenoma gene 1 (PLAG1) is the most frequent gain-of-function mutation found in pleomorphic adenomas of the salivary glands. To gain more insight into the regulation of PLAG1 function, we searched for PLAG1-interacting proteins. Using the yeast two-hybrid system, we identified karyopherin alpha2 as a PLAG1-interacting protein. Physical interaction between PLAG1 ...

Protocadherin-24 (PCDH24) is linked to the suppression of tumor growth and the inhibition of cell proliferation in the colon cancer cell line HCT116. We previously observed that β-catenin is localized to the plasma membrane when PCDH24 is expressed in these cells, but the molecular mechanisms by which PCDH24 induces the membrane localization of β-catenin remain largely unknown. To clarify these...

Glioblastoma (GBM) are characterized by increased invasion into the surrounding normal brain tissue. RTVP-1 is highly expressed in GBM and regulates the migration and invasion of glioma cells. To further study RTVP-1 effects we performed a pull-down assay using His-tagged RTVP-1 followed by mass spectrometry and found that RTVP-1 was associated with the actin polymerization regulator, N-WASP. T...

Abscisic acid (ABA) signaling plays important roles in plant growth, development and adaptation to various stresses. RCAR1/PYL9 has been known as a cytoplasm and nuclear ABA receptor in Arabidopsis. To obtain further insight into the regulatory mechanism of RCAR1/PYL9, a yeast two-hybrid approach was performed to screen for RCAR1/PYL9-interacting proteins and an R2R3-type MYB transcription fact...
