Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Fundamental Parameters for Totally Eclipsing Contact Binaries Observed by TESS

open access: yesThe Astrophysical Journal
Totally eclipsing contact binaries provide a unique opportunity to accurately determine mass ratios through photometric methods alone, eliminating the need for spectroscopic data.

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

open access: yesMolecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

The binary star

open access: yesпроект байкал, 2021
Baroque and classicism were called a binary star. In the national architecture, the avant-garde and neoclassicism can be also called a binary star. The model of succession of styles in architecture does not reflect the real situation in the 1920-1950s. Neoclassicism and different movements of “contemporary architecture” run parallel to each other both ...

Five New Sirius-like White Dwarf–Main-sequence Star Systems with MagAO-X

open access: yesThe Astronomical Journal
Most known white dwarfs in multiple systems with main-sequence stars have been discovered with M-type companions, because the white dwarf causes detectable UV excess and bluer colors than expected from a single M star.

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

open access: yesMolecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

CLOSE BINARY SYSTEMS ON LATE EVOLUTIONARY STAGES

open access: yesOdessa Astronomical Publications, 2017
Observational and theoretical progress in investigations of close binary stars allow to understand the nature and evolution of many types of close binary systems containing peculiar components: Wolf-Rayet stars, white dwarfs neutron stars and black holes.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

TESS Photometry and LAMOST Spectroscopy of 10 Detached Eclipsing Binaries

open access: yesThe Astronomical Journal
This study presents a thorough analysis of 10 detached eclipsing binaries that contain main-sequence stars. We have utilized a multifaceted approach, incorporating data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), TESS ...
