Promoter-driven splicing regulation in fission yeast

…, N Gabrielli, M Gogol, B Gómez-Escoda, T Ivanova… - Nature, 2008 - nature.com
The meiotic cell cycle is modified from the mitotic cell cycle by having a pre-meiotic S phase
that leads to high levels of recombination, two rounds of nuclear division with no intervening …

[HTML][HTML] Budding yeast complete DNA synthesis after chromosome segregation begins

T Ivanova, M Maier, A Missarova… - Nature …, 2020 - nature.com
To faithfully transmit genetic information, cells must replicate their entire genome before
division. This is thought to be ensured by the temporal separation of replication and …

[HTML][HTML] Autophagy and SARS-CoV-2-Old Players in New Games

T Ivanova, Y Mariienko, N Mehterov… - International Journal of …, 2023 - mdpi.com
At present it is well-defined that autophagy is a fundamental process essential for cell life
but its pro-viral and anti-viral role has been stated out with the COVID pandemic. However, …

Yox1 links MBF‐dependent transcription to completion of DNA synthesis

B Gómez‐Escoda, T Ivanova, IA Calvo… - EMBO …, 2011 - embopress.org
When DNA replication is challenged cells activate a DNA synthesis checkpoint, blocking
cell cycle progression until they are able to overcome the replication defects. In fission yeast, …

The DNA damage and the DNA replication checkpoints converge at the MBF transcription factor

T Ivanova, I Alves-Rodrigues… - Molecular Biology of …, 2013 - Am Soc Cell Biol
In fission yeast cells, Cds1 is the effector kinase of the DNA replication checkpoint. We
previously showed that when the DNA replication checkpoint is activated, the repressor Yox1 is …

Chromosome length and perinuclear attachment constrain resolution of DNA intertwines

I Titos, T Ivanova, M Mendoza - Journal of Cell Biology, 2014 - rupress.org
To allow chromosome segregation, topoisomerase II (topo II) must resolve sister chromatid
intertwines (SCI) formed during deoxynucleic acid (DNA) replication. How this process …

G1/S transcription and the DNA synthesis checkpoint: Common regulatory mechanisms

T Ivanova, B Gómez-Escoda, E Hidalgo, J Ayté - Cell Cycle, 2011 - Taylor & Francis
When DNA replication is challenged, cells activate a DNA-synthesis checkpoint blocking
cell cycle progression until they are able to overcome the replication defects. In fission yeast, …

Sensitive progesterone determination using a magnetic particle-based enzyme-linked immunosorbent assay

T Ivanova, T Godjevargova - Analytical letters, 2015 - Taylor & Francis
A highly sensitive magnetic nanoparticle enzyme immunoassay of progesterone was
established using horseradish peroxidase as a label. The “enzyme label” was prepared by …
