Thymic stroma and TFII-I: towards new targeted therapies.

Thymic epithelial tumors (TETs) have been characterized at the molecular level through bioptic sections and cell lines. Despite these advances, there is a need for a more thorough characterization of the thymic stroma in thymoma, particularly because of the diversity of cell types that populate the tumor and the absence of a healthy thymic counterpart. Recent work on healthy pediatric thymi - both in vitro and at the single-cell level - now sets the stage for new studies on their neoplastic counterparts.

Role of in the Emery-Dreifuss Muscular Dystrophy Cardiac Phenotype.

The locus is one of the most studied tumor suppressor loci in the context of several cancer types. However, in the last years, its expression has also been linked to terminal differentiation and the activation of the senescence program in different cellular subtypes. Knock-out (KO) of the entire locus enhances the capability of stem cells to proliferate in some tissues and respond to severe physiological and non-physiological damages in different organs, including the heart.

Mechanotransduction, nuclear architecture and epigenetics in Emery Dreifuss Muscular Dystrophy: tous pour un, un pour tous.

The alteration of the several roles that Lamin A/C plays in the mammalian cell leads to a broad spectrum of pathologies that - all together - are named laminopathies. Among those, the Emery Dreifuss Muscular Dystrophy (EDMD) is of particular interest as, despite the several known mutations of Lamin A/C, the genotype-phenotype correlation still remains poorly understood; this suggests that the epigenetic background of patients might play an important role during the time course of the disease. Historically, both a mechanical role of Lamin A/C and a regulative one have been suggested as the driving force of laminopathies; however, those two hypotheses are not mutually exclusive.
