A cellular system to study responses to a collision between the transcription complex and a protein‐bound nick in the DNA template

open access: yesFEBS Letters, EarlyView.
We present the cellular transcription‐coupled Flp‐nick system allowing the introduction of a Top1‐mimicking cleavage complex (Flpcc) at a Flp recognition target site within a controllable LacZ gene. LacZ transcription leads to the collision of RNA polymerase II (RNAPII) with Flpcc, and this causes RNAPII stalling, ubiquitination, and degradation.

PHANGS-HST Catalogs for ∼100,000 Star Clusters and Compact Associations in 38 Galaxies. I. Observed Properties

open access: yesThe Astrophysical Journal Supplement Series
We present the largest catalog to date of star clusters and compact associations in nearby galaxies. We have performed a V -band-selected census of clusters across the 38 spiral galaxies of the PHANGS–Hubble Space Telescope (HST) Treasury Survey, and ...

Playing with positive feedback: external pressure-triggering of a star-forming disc galaxy

open access: yes, 2015
Feedback in massive galaxies generally involves quenching of star formation, a favored candidate being outflows from a central supermassive black hole.

The Formation Of Massive Stars And The Effects Of Rotation On Star Formation

open access: yesEAS Publications Series, 2011
We first review the current debates about massive star formation over the last decade. Then we concentrate on the accretion scenario, emphasizing the evidences in favor of it. We study the basic properties of the accretion scenario in the spherical case.

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

open access: yesFEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Cluster Formation in a Filamentary Cloud: The Case of the Stellar Cluster NGC 2316

open access: yesThe Astronomical Journal
We present a multiwavelength analysis of the star cluster NGC 2316 and its surroundings. We estimated the physical parameters of the NGC 2316 cluster, including its shape (elongated), size ( R _cluster = 0.4 pc), distance (1.3 ± 0.3 kpc), and minimum ...

Star Formation: Lessons from Taurus [PDF]

open access: yesarXiv, 2000
The Taurus molecular cloud complex is the paradigm for quiescent, low-density, isolated star formation. Yet the age distribution of its stellar population indicates that star formation is a rapid and dynamic process, inconsistent with the old picture of magnetically-controlled protostellar cloud collapse. Instead, Taurus seems to have formed stars in a
