Our Vision
The natural world consists of hierarchical levels of complexity that range from subatomic particles and molecules to ecosystems and beyond.
This implies that, in order to explain the features and behavior of a whole system, a theory might be required that would operate at the corresponding hierarchical level, i.e. where self-organization processes take place.
In the past, biological research has focused on questions that could be addressed by a reductionist program of genetics.
The organism (and its development) is currently considered an epiphenomenon of its genes. However, a profound rethinking of the biological paradigm is now underway and it is likely that such a process will lead to a conceptual revolution emerging from the ashes of reductionism.
This revolution implies the search for general principles on which a cogent theory of biology might rely. Because much of the logic of living systems is located at higher levels, it is imperative to focus on them. Indeed, both evolution and physiology work on these levels.
Thus, by no means Systems Biology could be viewed a ‘simple’ ‘gradual’ extension of Molecular Biology.
Tumor Reversion
Phase transitions processes
The pathogenesis of several degenerative diseases, including cancer, mostly relies on a cell/tissue differentiation process ‘gone awry’.
A complex system is highly sensitive even to subtle changes in the surrounding milieu (the so-called morphogenetic field) when it enters near some critical points (the bifurcation points leading to metastable states, according to the Waddington’s landscape framework).
At these points, the system can experience a phase-transition, leading to different cell fate specification, upon the influence of different physical and molecular (namely toxicant, like nicotine) factors.
Thereby, it is of priceless value understanding the non-linear dynamics of such processes, to capture their architecture by means a proper mathematical modelling, and how to modify them through a pharmacological approach.
Namely, the natural polyol Inositol (and its phosphate derivatives) is investigated thoroughly, given that inositol showed to modulate epithelial-mesenchymal transition (EMT vs MET) by targeting the expression of several genes, the activation of the PI3K pathway, as well as the apoptotic process. By modulating EMT vs MET, Inositol can antagonize first steps of carcinogenesis while, by inhibiting apoptosis in normal cells it can easily counteract chemotherapy-induced effects on megakaryocytes. As inositol undergoes a complex metabolic transformation inside the cell, an in depth metabolomic study is currently ongoing to evaluate its metabolic fate.
Modulation of EMT is also at the core of the gene reprogramming that occur during tumor reversion. Tumor reversion induced by physical or molecular cues has been already reported.
We are investigating such processes by means of a model based on the therapeutic potential represented by protein extracts from embryo fish. Embryo fish extracts promote apoptosis and/or foster differentiation/reversion in different cancer types, both in vitro as well as in vivo.
Understanding how both inositol and embryo fish extract modulate phase transitions in cancer cells is therefore of critical relevance for translational medicine.
Developmental processes and theory of the organisms
Study of the developmental processes points primarily on early oocyte/embryo differentiating processes occurring during the early life stages.
We are investigating pathways involved in oocyte maturation (namely those involving steroidogenesis) by pointing out how changes in the overall cytoskeleton organization and in the oocyte/microenvironment cross talk can efficiently modulate oocyte maturation and further the implantation process.
To address these issues we are using a 3D-model – involving both the oocyte and an experimental reconstituted endometrium-like scaffold. The modulatory role of natural pharmacological compounds (like inositol, melatonin and α-lipoic acid) is under scrutiny to evaluate is such nutraceutical manipulation can improve the oocyte maturation process.
Furthermore, the potential utility of such compounds in treatment of infertility disorders (like Polycystic Ovary Syndrome) is currently under scrutiny.
Phenotypic Differentiation
Biophysical constraints
Phenotypic differentiation is underpinned by a complex molecular program, which involves both complex gene-regulatory circuits (behaving according to a non-linear dynamics) and molecular signaling.
However, these factors exert only a permissive role, while a more prominent effect is exercised by internal/external constraints (namely of physical origin), acting as instructive cues.
A paradigmatic example is provided by gravity, which showed to be instrumental in shaping cell differentiation in many experimental models.
We are investigating how microgravity and other physical cues may efficiently influence cell fate transitions in both normal and pathological conditions.
Moreover, as the effects of physical cues are mostly conveyed through the cytoskeleton (CSK) and the specialized cell-to-cell and cell-matrix adhesion structures, we are especially committed in investigating cytoskeleton and nucleoskeleton quantitative structure and dynamics.
To achieve a reliable systems biology representation of such complex processes, tailored, mathematical modelling approaches and high performance computing studies are usually developed.
