STIM1 and STIM1L as regulators of cytosolic calcium clearance in skeletal muscle

Room: room B04.2222

Speaker: Loann LAUBRY, Pr. Maud FRIEDEN laboratory

Summary: Calcium is a key element involved in many cellular processes. Despite the importance of calcium regulation in muscle cells, many unknowns remain. Loann LAUBRY in collaboration with other researchers from Maud FRIEDEN’s laboratory is exploring the role of two different isoforms of a protein, STIM1 and STIM1L, known to regulate calcium entry. His work proposes that these proteins are also regulating calcium clearance during muscle formation.

Core clock transcription factor Bmal1 drives circadian expression of beta-cell specific miR-184-3p, required for proper islet function

Room: auditorium P. Boymond B02.2226

FEB 21 2023

Internalized GPCRs in endosomes mediate a sustained signaling response

Room: auditorium P. Boymond B02.2226

Speaker: Lucie OBERHAUSER, Pr. Miriam STOEBER laboratory

Summary: G protein-coupled receptors (GPCRs) play ubiquitous roles in physiological processes, yet several aspects that regulate GPCR function remain unknown. Studying signalling at different subcellular locations, in particular, could provide essential new insights into the effects of endogenous ligands and exogenous GPCR-targeting drugs. Lucie OBERHAUSER, in collaboration with other researchers from Prof. Miriam STOEBER’s laboratory, is investigating the impact of location on the GPCR downstream response, with a particular emphasis on signalling of GPCRs in endosomes.

 

Targeting the extracellular matric enriched tumor microenvironment in Glioblastomas

Room: auditorium P. Boymond B02.2226

Speaker: Alexandra BONDAZ, Pr. Bernhard WEHRLE-HALLER laboratory

Summary: Glioblastoma is one of the most common and aggressive forms of brain cancer. Finding new therapeutic approaches is essential, as the chances of survival for patients are very low. Alexandra BONDAZ in collaboration with other researchers from the laboratory of Prof. Bernhard WEHRLE-HALLER and Prof. Denis MIGLIORINI is exploring the possibility of hindering the development of an adequate tumor microenvironment to limit the growth of the cancer.

Controlling the activity of Plk1 with light

Room: auditorium P. Boymond B02.2226

Speaker: Victoria VON GLASENAPP, Pr. Monica GOTTA laboratory

Summary: The human body produces 330billion new cells per day through cell division. This essential process is tightly regulated by, among others, the kinase PLK-1.Victoria VON GLASENAPP from Prof. Monica GOTTA’s laboratory in collaboration with the laboratory of Prof. Nicolas WINSSINGER is developing a new tool to control the activity of PLK-1 with light. Their innovative approach allows them to have a better temporal control over the activity of PLK-1 to study the cell cycle and it should lead to a better global understanding of cell division.

Mechanisms promoting Pseudomonas aeruginosa adhesion to the Cystic Fibrosis airway epithelium

Room: auditorium P. Boymond B02.2226

Speaker: Mehdi BADAOUI, Pr. Marc CHANSON laboratory

Summary: Chronic lung infections by Pseudomonas aeruginosa is the leading cause of respiratory failure in people with cystic fibrosis. Mehdi BADAOUI in collaboration with other researchers from Prof. Marc CHANSON’s laboratory discovered that overexpression of the protein Vav3 promotes these infections by creating bacterial docking stations on airways’ surface. They identified the role played by the RNA-binding protein HuR in Vav3 overexpression, opening up new potential therapeutic options.

Room: auditorium P. Boymond B02.2226

Speaker: Giulia LUCIBELLO, Pr. Roberto COPPARI laboratory

Summary: After decades of research on diabetes, treatments of insulin deficiency remain unsatisfactory and sometimes lead to an overproduction of ketone bodies that are toxic to patients. Giulia LUCIBELLO in collaboration with other researchers from Prof. Roberto COPPARI laboratory is trying to determine how the protein S100A9 can reduce ketone body levels using different diabetic mouse models.

 

How do spindle poles control spindle symmetry?

Room: auditorium P. Boymond B02.2226

Speaker: Alexandre THOMAS, Pr. Patrick MERALDI laboratory

Summary: During cell division, chromosomes are duplicated and equally distributed between two new cells. Their segregation relies on centrosomes which must also be duplicated to organize a spindle of microtubules that pull apart chromosomes. Alexandre THOMAS in collaboration with other researchers from Patrick MERALDI laboratory is carrying out microscopy experiments to determine the role of both the spindle poles and the centrosome age in the regulation of spindle (a)symmetry.

Mild replication stress causes premature centriole disengagement via sub-critical Plk1 activity under the control of ATR-Chk1

Room: auditorium A. Renold B01.2426

Speaker: Devashish DWIVEDI, Pr. Patrick MERALDI laboratory

Summary: Centrioles are cellular structures that help separate the chromosomes into the daughter cells during cell division. Under mild replication stress, they desynchronize from the rest of the process, a mismatch that can lead to cancer. Devashish DWIVEDI in collaboration with other researchers from Patrick MERALDI’s laboratory conducts several cell experiments to determine the exact molecular mechanisms involved in centrosome desynchronization.
