Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Glass transition temperatures of binary oxides from ab initio simulations

APL Materials, 2023
The glass transition temperatures of common binary oxides, including those with low glass-forming ability, are estimated using pair distribution functions (PDFs) from ab initio molecular dynamics simulations.

Thermal behaviour of zircon/zirconia-added chemically durable borosilicate porous glass [PDF]

, 2013
Macroporous alkali resistant glass has been developed by making additions of zirconia (ZrO2) and zircon (ZrSiO4) to the sodium borosilicate glass system SiO2–B2O3 Na2O. The glass was made using a traditional high temperature fusion process.

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Glass transition temperature prediction of disordered molecular solids

npj Computational Materials, 2021
Glass transition temperature, T g, is the key quantity for assessing morphological stability and molecular ordering of films of organic semiconductors. A reliable prediction of T g from the chemical structure is, however, challenging, as it is sensitive ...

PbSe quantum dots grown in a high-index low-melting-temperature glass for infrared laser applications [PDF]

, 2013
PbSe quantum dots (QDs) were grown in high-refractive-index low-melting-temperature lead-phosphate glass. QDs with various sizes ranging from 2 nm to 5.3 nm were grown by controlling the growth parameters, heat-treatment temperature and time.

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

Molecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

Thermal and structural properties of ZnO-Bi2O3-B2O3 glasses doped with NiO

Eurasian Journal of Physics and Functional Materials, 2022
Among new low melting glasses, bismuthate glass is deemed to have the most potential. Current studies of these glasses focus on the thermal and structural influence of the additional oxide (NiO).
