(Submitter supplied) It is currently unclear whether tissue changes surrounding multifocal epithelial tumors are a cause or consequence of cancer. Here, we provide evidence that loss of mesenchymal Notch/CSL signaling causes tissue alterations, including stromal atrophy and inflammation, which precede and are potent triggers for epithelial tumors. Mice carrying a mesenchymal-specific deletion of CSL/RBP-JK, a key Notch effector, exhibit spontaneous multifocal keratinocyte tumors that develop after dermal atrophy and inflammation. more...

(Submitter supplied) Senescence of stromal fibroblasts has been linked to establishment of cancer associated fibroblasts (CAF) and aging-associated increase of tumors. However, in clinically occurring carcinomas, density and proliferation of CAFs are frequently increased rather than decreased. We previously showed that genetic deletion or down-modulation of the canonical Notch effector CSL/RBP-Jκ in skin dermal fibroblasts is sufficient for CAF activation with consequent development of multifocal keratinocyte tumors. more...

(Submitter supplied) Down-modulation or loss-of-function mutations of the Notch 1 and 2 genes are associated with development of squamous cell carcinoma (SCC), a very frequent and therapy-resilient malignancy in skin, head/neck (H/N), lung and other surface epithelia. In this context, surprisingly little is known on the role of CSL (RBP-Jk), key effector of canonical Notch signaling endowed with intrinsic transcription repressive function. more...

(Submitter supplied) Genomic instability is a hallmark of cancer. Whether or not it also occurs in cancer-associated fibroblasts (CAFs) is a question of importance for the cancer/stromal cell co-evolution process. We find that DNA damage, telomere shortening and chromosome fusions occur at early times of CAF activation, as triggered by silencing of the CSL/RBP-J-κ gene in primary human dermal fibroblasts (HDFs) from multiple individuals. more...

(Submitter supplied) CSL is a key transcription factor, mostly acting as a repressor. While known as main effector of Notch signaling, it can also play Notch-independent functions. Despite the wide interest in CSL, the mechanisms responsible for its own regulation have been little studied. We recently showed that CSL down-modulation in human dermal fibroblasts (HDFs) leads to conversion into cancer associated fibroblasts, which promote keratinocyte tumor development. more...

(Submitter supplied) There is evidence that brain tumor cells may hijack self-renewal mechanism that regulate stem cell maintenance during normal development. Notch signaling is fundamental for maintaining normal neural stem cells in an undifferentiated state and has been implicated in in the maintenance of brain tumor stem cells as well. We used microarrays to detail the global gene expression program in murine brain tumors lacking RBPjk, an indispensable mediator of the Notch signaling pathway in the cell nucleus.

(Submitter supplied) Notch signaling is an important regulator of stem cell differentiation. All canonical Notch signaling is transmitted through the DNA-binding protein CSL and hyperactivated Notch signaling is associated with tumor development; thus it may be anticipated that CSL deficiency should reduce tumor growth. In contrast, we report that genetic removal of CSL in breast tumor cells caused accelerated growth of xenografted tumors. more...

(Submitter supplied) The age-associated increase of cancer risk has been linked with stromal fibroblast senescence and early steps of Cancer Associated Fibroblast (CAF) activation. Surprisingly little is known about the role of androgen receptor (AR) signalling in this context. We show that AR expression is down-modulated in stromal fibroblasts underlying premalignant skin cancer lesions (actinic keratoses, AK) as well as in CAFs from the three major skin cancer types, squamous (SCC) and basal cell (BCC) carcinomas and melanomas. more...
