RESEARCH TOPICS
i) Stress response
ii) Cytoskeleton
iii) Cell communities.
CURRENT PROJECTS
The laboratory is focused on the analysis of the spatial control and the dynamics of gene expression and proteostasis in eukaryotic cells, specifically in response to stress and aging.
The scientific topics of the laboratory are the following:
1.Protein quality control, autophagy, cell vitality, cell aging, and apoptosis as affected by genetic factors, environmental and intracellular stressors like heat, toxins, radiation, chemicals, reactive oxygen, and nitrogen species. Studies of the dynamics of the stress response, onset and course of apoptosis. Studies of the effect of different stresses on membrane structure. Studies are performed in liquid cultures of wild-type or mutant cells, and also in the context of multicellular cell communities (giant colonies).
2.Regulatory functions of cytoskeleton under physiological and stress
conditions and in aging. Study of gamma-tubulin functions in connecting
nuclei organization with cytoskeleton dynamics in dividing and differentiated
cells. Study of actin dynamics in cell division and differentiation.
To analyze the expression of specific proteins of interest and changes
in their behavior and distribution we construct various wild-type or
mutant versions of protein fusions with GFP, mRFP, mCherry, yTagRFP-T
and ymTagBFP from their chromosomal sites or from plasmids in
Saccharomyces cerevisiae and Arabidopsis thaliana.
The yeast cells and plant cell lines are used in live-cell imaging,
biochemical and proteomics studies.
