Project description:Tissue injury induces changes in cellular identity, but the underlying molecular mechanisms remain obscure. Here, we show that upon damage, epidermal cells at the wound edge convert to an embryonic-like state, altering particularly the cytoskeletal/extracellular matrix (ECM) components and differentiation program. We show that SOX11 and its closest relative SOX4 dictate embryonic epidermal state, regulating genes involved in epidermal development as well as cytoskeletal/ECM organization. Correspondingly, postnatal induction of Sox11 represses epidermal terminal differentiation while deficiency of Sox11 and Sox4 accelerates differentiation and dramatically impairs cell motility and re-epithelialization. Amongst the embryonic genes reactivated at the wound edge, we identify fascin actin-bundling protein 1 (FSCN1) as a critical direct target of SOX11 and SOX4 regulating cell migration. Our study identifies the reactivated embryonic gene program during wound repair and demonstrates that SOX11 and SOX4 play a key part in this process

Project description:The early retinal progenitor-expressed gene Sox11 regulates the timing of the differentiation of retinal cells. Sry-related HMG box (Sox) proteins play diverse and critical roles in a variety of morphogenetic processes during embryonic development. Sox11 and Sox4 are members of the SoxC subtype, and we found that Sox11 was strongly expressed in early retinal progenitor cells, and that when expression of Sox11 subsided around birth, Sox4 expression began. To analyze the role of Sox11 and Sox4 in retinal development, we perturbed their expression pattern by expressing them ectopically in retinal explant culture. Overexpression of Sox11 or Sox4 in retinal progenitors resulted in similar phenotypes, that is, increased cone cells and decreased Muller glia. Sox11-knockout retinas showed delayed onset and progress of differentiation of early-born retinal cells during the embryonic period. After birth, retinal differentiation took place relatively normally, probably because of the redundant activity of Sox4, which starts to differentiate around birth. Neither overexpression nor loss-of-function analysis gave any evidence that Sox11 and Sox4 directly regulate transcription of genes critical to early-born retinal cells. However, histone H3 acetylation status of the early neurogenic genes was lowered in knockout retinas, suggesting that Sox11 regulates the timing of differentiation in early-born retinas by creating an epigenetic state that helps to establish the competency to differentiate. We also found that the unique expression patterns of Sox11 and Sox4 may be achieved by the Notch signaling pathway and by epigenetic regulation. Taking our findings together, we propose that the precise regulation of Sox11 and Sox4 expression during retinogenesis by multiple mechanisms leads to the fine adjustment of retinal differentiation. To delineate the molecular mechanisms underlying the retinal action of Sox11, we performed microarray analysis of E18 retinas from wild-type and Sox11 knockout mice. Total RNA was obtained from each one retina of Sox11 knockout and wild-type littermate embryos at E18.

Project description:The neural transcription factor SOX11 is overexpressed in aggressive lymphoid neoplasms mainly in mantle cell lymphoma (MCL). We have recently demonstrated SOX11 tumorigenic potential in vivo by showing a significant reduction on tumor growth of SOX11-knockdown MCL cells in xenograft experiments, confirming the clinical observations that SOX11 may play an important role in the aggressive behavior of MCL (Vegliante et al., 2013). However, the specific mechanisms regulated by SOX11 that promote the oncogenic and rapid tumor growth of aggressive MCL still remain to be elucidated. To further characterize the potential oncogenic mechanisms regulated by SOX11 in MCL, we have analyzed the GEP derived from the xenograft SOX11-positive and knockdown xenograft derived tumors. Differential gene expression between SOX11-positive Z138 and SOX11-negative Z138 MCL cell lines xenotransplanted in SCID mices derived tumors.

Differential gene expression between SOX11-positive Z138 and SOX11-negative Z138 MCL cell lines xenotransplanted in SCID mices derived tumors. To determine the transcriptional programs regulated by SOX11 we first generated a MCL cellular model with reduced SOX11 protein levels by infecting MCL cell lines with lentiviral particles carrying shRNA plasmids specifically targeting SOX11 (shSOX11.1 and shSOX11.3). Next, CB17-severe combined immunodeficient (CB17-SCID) mice (Charles River Laboratory, Wilmington, MA) were subcutaneously inoculated into their lower dorsum with Z138 shSOX11.1, shSOX11.3, shControl in Matrigel basement membrane matrix and compared the GEP of SOX11-positive and SOX11-negative MCL xenotransplant derived tumors using the Affymetrix U133+2.0 microarrays.
