Is periapical surgery follow-up with only two-dimensional radiographs reliable? A retrospective cohort type sensitivity study
2021
Background Two-dimensional (2D) radiographic techniques are commonly used for assessing lesion prognosis after endodontic surgery. The present retrospective cohort study analyzes the sensitivity and ability of different radiographic techniques in obtaining area and volume measurements of periapical lesions. Material and Methods Preoperative and follow-up (6-48 months) periapical and panoramic radiographs (index test) and cone-beam computed tomography (CBCT) images (reference standard) were selected from an endodontic microsurgery database. Sensitivity was analyzed independently by two examiners. The areas of the 2D radiographic images and CBCT volumes were studied using Itk-Snap software an…
MCC1019, a selective inhibitor of the Polo-box domain of Polo-like kinase 1 as novel, potent anticancer candidate
2019
Polo-like kinase (PLK1) has been identified as a potential target for cancer treatment. Although a number of small molecules have been investigated as PLK1 inhibitors, many of which showed limited selectivity. PLK1 harbors a regulatory domain, the Polo box domain (PBD), which has a key regulatory function for kinase activity and substrate recognition. We report on 3-bromomethyl-benzofuran-2-carboxylic acid ethyl ester (designated: MCC1019) as selective PLK1 inhibitor targeting PLK1 PBD. Cytotoxicity and fluorescence polarization-based screening were applied to a library of 1162 drug-like compounds to identify potential inhibitors of PLK1 PBD. The activity of compound MC1019 against the PLK1…
Simultaneous reduction of MAD2 and BUBR1 expression induces mitotic spindle alterations associated with p53 dependent cell cycle arrest and death
2014
RNA interference of MAD2 and BUBR1 genes causes mitotic spindle alterations, aneuploidy and cell cycle arrest p53-dependent.
2009
The Spindle Assembly Checkpoint (SAC) is a cellular surveillance mechanism that functions to ensure faithful chromosome segregation during mitosis. Failure of this checkpoint or alteration in expression of SAC proteins (MAD2, BUB1, BUBR1 and others) can result in aneuploidy, a state of having abnormal numbers of chromosomes. MAD2 haploinsufficiency resulted in aneuploidy in MEFs and colon cancer cells in culture. Thus, spindle checkpoint components might have additional functions not-checkpoint-related functions that when disrupted contribute to tumorigenesis. Here we investigated the effects of MAD2 or BUBR1 transcriptional silencing in HCT-116 cells. Transient reduction of MAD2 (40%) and …
