AI Article Synopsis
- Efficient synthesis methods were developed for mono-substituted anthraquinones and anthra[2,3-d]oxazole-2-thione-5,10-dione derivatives, which were then tested for their effects on PC-3 cancer cell lines.
- Compounds 8, 14, 17, and 23 were selected by the NCI for further evaluation, with compounds 12, 17, and 19 tested for their impact on topoisomerase I-mediated DNA relaxation.
- Among these, compound 17 demonstrated the highest potency, exhibiting strong inhibition against the PC-3 cell line and effectively suppressing topoisomerase I activity at low concentrations, indicating promising potential for anticancer drug development.
Article Abstract
The efficient synthesis of mono-substituted anthraquinones and ring fusion into anthra[2,3-d]oxazole-2-thione-5,10-dione derivatives were developed, and all the compounds were tested for their cytotoxicity against PC-3 cancer cell lines. Compounds 8, 14, 17 and 23 were selected by the NCI and 12, 17 and 19 were evaluated for topoisomerase I-mediated DNA relaxation. Among them, 17 appeared to be the most active compound of this series and not only showed higher inhibition when indicated from the low IC50 values against PC-3 cancer cell line but also attenuated the in vitro topoisomerase I-mediated DNA relaxation at low micromolar concentrations. All test compounds exhibited different cytostatic and cytotoxic activities for further developing potential anticancer drugs.

Overexpression of miR17 ~ 92 in Myeloid Cells in Mice Increased Bone Mass Through Reduced Bone Resorption and Increased Bone Formation in Sex-Dependent Manner.

This study assessed the feasibility of miR17 ~ 92-based antiresorptive strategy by determining the effects of conditional transgenic (cTG) overexpression of miR17 ~ 92 in myeloid cells on bone and osteoclasts. Osteoclasts of male and female cTG mutant mice each showed 3- to fivefold overexpression of miR17 ~ 92 cluster genes compared to those of age- and sex-matched wildtype (WT) littermates. Male but not female cTG mutant mice had more trabecular and cortical bones as well as lower bone resorption reflected by reduction in osteoclast number and resorbing surface.

Uncovering topologically associating domains from three-dimensional genome maps with TADGATE.

Topologically associating domains (TADs) are essential components of three-dimensional (3D) genome organization and significantly influence gene transcription regulation. However, accurately identifying TADs from sparse chromatin contact maps and exploring the structural and functional elements within TADs remain challenging. To this end, we develop TADGATE, a graph attention auto-encoder that can generate imputed maps from sparse Hi-C contact maps while adaptively preserving or enhancing the underlying topological structures, thereby facilitating TAD identification.

Partial wrist arthrodesis (PWA) is a salvage procedure used in advanced wrist arthritis and has traditionally been performed via an open dorsal approach. In recent years, surgeons have moved towards arthroscopic fusions to minimise soft tissue damage and preserve vascular supply, increase union rates and hasten recovery. The purpose of this study is to synthesise the current literature on the outcomes of arthroscopic PWA.
