(Submitter supplied) Purpose: Define HDAC4 signature Outcome: HDAC4 is required for the repression of a senescence signature. HDAC4 KO promotes the expression of inflammatory genes, the derepression of ERVs and the accumulation of DNA damage. All together these signalling pathways lead to permanent cell-cycle arrest in low grade tumor cells and pre-transformation models, while they weaken the replicative potential of primary normal cells.

(Submitter supplied) Purpose: Define the epigenetic program of HDAC4 Outcome: HDAC4 controls the H3K27me3 of repetitive elements of retroviral origin (ERVs) and the H3K27 deacetylation of typical and super-enhancers found to be activated during senescence. The former response is due to the remodeling of the chromatin that sorrounds ERVs, while the latter is directly mediated by HDAC4 binding to the chromatin and the local deacetylation.

(Submitter supplied) Purpose: Define the transcriptional networks supervising class IIa HDAC expression. Outcome: We demonstrate that MEF2D is the key factor controlling HDAC9 transcription. Comprehensive genome-wide studies demonstrate that HDAC4 and HDAC9 supervise different genetic programs and show both specific and common genomic bindings. Although the number of MEF2-target genes commonly regulated is similar, only HDAC4 represses many additional genes that are not MEF2D targets. more...

(Submitter supplied) Cellular senescence is a homeostatic program associated with tumor suppression, wound healing, and certain age related pathologies. Senescent cells display a repressive chromatin configuration thought to stably silence proliferation-promoting genes, while at the same time activate an unusual form of immune surveillance involving a secretory program referred to as the senescence-associated secretory phenotype (SASP). more...

(Submitter supplied) Histone deacetylases (HDACs) are known to be a class of enzymes that remove acetyl groups from lysine chains on histones or other proteins, and play a crucial role in epigenetic regulation and aging process. Previous studies have identified that HDAC4 is down-regulated in aged and UV-irradiated skin in vivo. Therefore, HDAC4 may be an important role in skin aging process. However, the role of HDAC4 in skin aging is rarely known. more...

(Submitter supplied) Senescent cells affect many physiological and pathophysiological processes. While select genetic and epigenetic elements for senescence induction have been identified, the dynamics, epigenetic mechanisms and regulatory networks defining senescence competence, induction and maintenance remain poorly understood, precluding the deliberate therapeutic targeting of senescence for health benefits. Here, we examined the possibility that the epigenetic state of enhancers determines senescent cell fate. more...

(Submitter supplied) Treatment induced senescence (TIS) is a terminal cell cycle arrest program, increasingly recognized as a tumor suppressor mechanism complementing apoptosis in response to standard chemotherapy regimens. In particular cells with blocked apoptotic pathways rely on senescence as the only remaining failsafe mechanism to keep the neoplastic growth in check. However, little is known about biological properties, long-term fate of senescent tumor cells and their impact on the microenvironment. more...

(Submitter supplied) We are interested in genetic programs and mutations which impact on tumor development and sensitivity to anticancer therapies. Utilizing Emu-myc transgenic mice, which spontaneously develop aggressive B-cell lymphomas, we aimed here to study the effects of drug responses in vivo. For that purpose, primary lymphomas from the Emu-myc transgenic mice were transplanted in several immunocompetent recipients and exposed to a single dose Cyclophosphamide (CTX), a standard component of chemotherapeutic regimens used to treat human B-cell lymphomas. more...
