Live cell imaging of meiosis in Arabidopsis thaliana

open access: yeseLife, 2019
To follow the dynamics of meiosis in the model plant Arabidopsis, we have established a live cell imaging setup to observe male meiocytes. Our method is based on the concomitant visualization of microtubules (MTs) and a meiotic cohesin subunit that ...

Aberrant expression of nuclear prothymosin α contributes to epithelial‐mesenchymal transition in lung cancer

open access: yesMolecular Oncology, EarlyView.
Nuclear prothymosin α inhibits epithelial‐mesenchymal transition (EMT) in lung cancer by increasing Smad7 acetylation and competing with Smad2 for binding to SNAI1, TWIST1, and ZEB1 promoters. In early‐stage cancer, ProT suppresses TGF‐β‐induced EMT, while its loss in the nucleus in late‐stage cancer leads to enhanced EMT and poor prognosis.

Thyroid status modulates T lymphoma growth via cell cycle regulatory proteins and angiogenesis [PDF]

open access: yes, 2014
We have shown in vitro that thyroid hormones (THs) regulate the balance between proliferation and apoptosis of T lymphoma cells. The effects of THs on tumor development have been studied, but the results are still controversial.

Cell Cycle-Dependent Expression Dynamics of G1/S Specific Cyclin, Cellulose Synthase and Cellulase in the Dinoflagellate Prorocentrum donghaiense

open access: yesFrontiers in Microbiology, 2017
Dinoflagellates undergo a typical eukaryotic cell cycle consisting of G1, S, G2, and M phases and some of the typical cell cycle related genes have been computationally identified.

Cdc13 (cyclin B) is degraded by autophagy under sulfur depletion in fission yeast

open access: yesAutophagy Reports, 2022
Cyclins are degraded by the anaphase-promoting complex/cyclosome (APC/C)-mediated proteasome in normal mitosis. We showed that Cdc13 (cyclin B) is also degraded by macroautophagy/autophagy in sulfur-deficient fission yeast.

Cell Cycling Models of Carcinogenesis: A Complex Systems Analysis [PDF]

open access: yesarXiv, 2004
A new approach to the modular, complex systems analysis of nonlinear dynamics in cell cycling network transformations involved in carcinogenesis is proposed. Carcinogenesis is a complex process that involves dynamically inter-connected biomolecules in the intercellular, membrane, cytosolic, nuclear and nucleolar compartments that form numerous inter ...

Determination of ADP/ATP translocase isoform ratios in malignancy and cellular senescence

open access: yesMolecular Oncology, EarlyView.
The individual functions of three isoforms exchanging ADP and ATP (ADP/ATP translocases; ANTs) on the mitochondrial membrane remain unclear. We developed a method for quantitatively differentiating highly similar human ANT1, ANT2, and ANT3 using parallel reaction monitoring. This method allowed us to assess changes in translocase levels during cellular

p25/Cdk5-mediated retinoblastoma phosphorylation is an early event in neuronal cell death [PDF]

open access: yes, 2005
In large models of neuronal cell death, there is a tight correlation between Cdk5 deregulation and cell-cycle dysfunction. However, pathways that link Cdk5 to the cell cycle during neuronal death are still unclear.

Tumor suppressor and anti-inflammatory protein: an expanded view on insulin-degrading enzyme (IDE) [PDF]

open access: yesarXiv, 2008
In 1994, I conjectured that insulin-degrading enzyme (IDE) acts as an inhibitor of malignant transformation by degrading insulin and thus preventing this major growth-stimulatory hormone from binding and thereby inactivating the retinoblastoma tumor suppressor protein (RB).

Cyclin D1 Expression Is Regulated Positively by the p42/p44MAPK and Negatively by the p38/HOGMAPK Pathway*

open access: yesJournal of Biological Chemistry, 1996
We have previously shown that the persistent activation of p42/p44MAPK is required to pass the G1 restriction point in fibroblasts (Pagès, G., Lenormand, P., L'Allemain, G., Chambard, J. C., Meloche, S., and Pouysségur, J. (1993) Proc. Natl. Acad. Sci. U.
