2024 research activities
Overview
The molecular basis of genetics and related biological processes are under investigation in our Department. The investigators approach these processes from the most reduced and reconstructed systems up to more systemic and computational analysis. Different organisms are employed including virus, yeast, Drosophila, mouse and human. These animal models and cell culture systems are used to study the mechanisms of;
a. Basic processes in gene expression, such as transcription, translation and protein degradation.
b. Cellular responses to various stimuli, such as cytokines, growth factors and exposure to DNA-damage.
c. Regulation of cell growth, senescence, differentiation and death.
d. Development; Mechanistic view of zygote to embryo transition and development of various organs, such as brain, muscles, bones and pancreas.
e. Genetic and acquired diseases such as cancer and virus infection. Embryonic stem cell biology, early development and advance human disease modeling.
f. Study of pluripotent stem cell biology and epigenetic reprogramming.
g. Computational and system biology. The function/evolution of genes and their diversification.

Deciphering Cellular ReprogrammingFollowing a breakthrough that was made in 2006 (by Takahashi & Yamanaka), today we can reverse cellular differentiation, and generate induced pluripotent stem cells from somatic cells by epigenetic “reprogramming”. We investigate what are the dramatic molecular changes happening in the cell during reprogramming and how they are connected to similar in-vivo processes. We pointed out two chromatin regulators that play a role in this process, one is essential for reprogramming (Utx, Mansour et al 2012), and the other (Mbd3/NuRD, Rais et al 2013) is an obstacle, which upon its near-removal the reprogramming becomes dramatically faster and synchronized.Understanding Naïve and Primed Pluripotent StatesBeing able to generate all cell types, mouse embryonic stem cells are a most valuable tool for research. They can be found in the developing mouse embryo in two distinct states: naïve – in the blastocyst, and primed – in the post-implantation epiblast. These two states are distinct in various aspects, most notable, only naïve cells can contribute efficiently to chimera. Naïve and primed cells can be sustained in-vitro, and are dependent on distinct signaling. In human, naïve stem cells were out of reach for a long time. We investigate the regulation of naïve and primed pluripotent stem cell in mouse and human. Specifically, we were able to maintain human stem cells in a “naive” state, with distinct molecular and functional properties, including enhanced ability to contribute to cross-species mouse chimeric embryos (Gafni et al, 2013). In addition, we found that mRNA methylation has a critical role in facilitating degradation of pluripotent genes, an essential step during the switch from naïve to primed states, both in-vitro and in-vivo (Geula et al, 2014). Our current studies involve elucidating molecular regulation of these states across different species, and define how their molecular architecture dictates their functional competence.Human-Mouse Cross-Species ChimerismHuman stem cells that are sustained in naïve culture conditions, can be injected to mouse blastocyst and contribute to cross-species chimera (Gafni et al, 2013). We investigate these chimeric mice, which are valuable tool for human disease modeling in a whole-organism context.

Molecular and Cell Biology of RNA virusesRNA viruses including corona, zika and dengue are a major threat to human health. We study how RNA viruses interact with their host cells and transform them into viral manufactories.Our main model is enteroviruses - common viral pathogens that cause severe medical complications in humans, with no available therapeutic treatments.We investigate how enteroviruses remodel the structure and function of host organelles to generate an environment favorable to virus replication.Another key question we tackle is how enteroviruses, that express only a small number of proteins, take control of human cells with complex protein machineries. We study the different roles of viral proteins and the mechanisms they use to hijack host machineries.We aim to piece together the complete program of enterovirus replication. This could lead to the development of new antiviral therapeutics.
