Expression data from differentiating ES cells expressing Snail during Wnt inhibition

ABSTRACT: ES cells differentiated in the presence of the Wnt inhibitor DKK1 fail to express the transcription factor Snail and undergo EMT. We generated an ES cell line, A2.snail, that induced Snail expression upon addition of doxycycline addition. Microarrays were used to gain a global picture of ES cell differentiation at early timepoints after Snail was expressed during Wnt inhibition.

Expression data from differentiating ES cells expressing Snail during Wnt inhibition

Project description:ES cells differentiated in the presence of the Wnt inhibitor DKK1 fail to express the transcription factor Snail and undergo EMT. We generated an ES cell line, A2.snail, that induced Snail expression upon addition of doxycycline addition. Microarrays were used to gain a global picture of ES cell differentiation at early timepoints after Snail was expressed during Wnt inhibition. A2.snail ES cells, which express Snail upon addition of doxycycline, were differentiated as embryoid bodies in differentiation media and DKK1. Total RNA was harvested from control (no doxycycline) and Snail-induced (doxycycline at day 2) cultures at 6, 12, and 24 hours after doxycycline addition (corresponding to days 2.25, 2.5, and 3 of differentiation).

Expression data from differentiating Flk1- and Flk1+ ES cells expressing Snail during Wnt inhibition

Project description:ES cells differentiated in the presence of the Wnt inhibitor DKK1 fail to express the transcription factor Snail and undergo EMT or mesoderm differentiation. We generated an ES cell line, A2.snail, that induced Snail expression upon addition of doxycycline addition. Microarrays were used to gain a global picture of Flk1- and Flk1+ cells generated one day after Snail was expressed during Wnt inhibition. A2.snail ES cells, which express Snail upon addition of doxycycline, were differentiated as embryoid bodies in differentiation media and DKK1. Snail-induced cultures uniquely develop a select population of Flk1+ cells. Total RNA was harvested from sorted control (no doxycycline) Flk1- cells and sorted Snail-induced (doxycycline at day 2) Flk1- and Flk1+ cells at day 3 of differentiation.

Expression data from differentiating ES cells expressing miR-200c and miR-141

Project description:ES cells express the miR-200 family which becomes down-regulated during the course of differentiation in serum. We generated an ES cell line which expresses miR-200c and miR-141 upon addition of doxycycline. Microarrays were used to gain a global picture of differentiation when miR-200c and miR-141 expression were maintained throughout differentiation through the addition of doxycycline. A2.miR200c ES cells, which express miR-200c/miR-141 upon addition of doxycycline, were differentiated as embryoid bodies in six petri dishes. Half of the samples were treated with doxycycline on days 2 and 4 of differentiation, and RNA was collected from all samples on days 3, 4, and 5.

Title: Non-canonical functions of SNAIL drive context-specific progression

Project description:SNAIL is a key transcriptional regulator in embryonic development and cancer. Its effects in physiology and disease are believed to be linked to its role as a master regulator of epithelial-to-mesenchymal transition (EMT). Here, we report EMT-independent oncogenic SNAIL functions in cancer. Using genetic models, we systematically interrogated SNAIL effects in various oncogenic backgrounds and tissue types. SNAIL related phenotypes displayed remarkable tissue- and genetic context-dependencies, ranging from protective effects as observed in KRAS- or WNT-driven intestinal cancers, to dramatic acceleration of tumorigenesis, as shown in KRAS-induced pancreatic cancer. Unexpectedly, SNAIL-driven oncogenesis was not associated with E-cadherin downregulation or induction of an overt EMT program. Instead, we show that SNAIL induces bypass of senescence and cell cycle progression through p16INK4A-independent inactivation of the Retinoblastoma (RB)-restriction checkpoint. Collectively, our work identifies novel non-canonical EMT-independent functions of SNAIL and unravel its complex context-dependent role in cancer.

4T1 cells with Control vs SNAIL vs SNAIL/FBXO11

Project description:Transcriptional profiling of mouse 4T1 breast cancer cells stably tranduced with pLEX-MCS based lentivirus. Three groups were compared, Vector cells, SNAIL expressing cells; and SNAIL+FBXO11 expressing cells. SNAIL expression induced strong EMT phenotype while SNAIL/FBXO11 reversed cells back to epithelial cells.
