Analysis of lungs from embryonic day 18.5 C57BL/6 mutants deficient for the High Mobility Group AT-hook Protein 2 (HMGA2). High-mobility-group proteins are abundant non-histone chromatin-associated proteins. Results provide insight into the role of HMGA2 in lung development.

(Submitter supplied) The high-mobility-group (HMG) proteins are the most abundant non-histone chromatin-associated proteins. Here we deciphered the role of the high mobility group AT-hook protein 2 (HMGA2) during lung development by analyzing the lung of Hmga2 deficient mice (Hmga2-/-).We found that Hmga2 is expressed in the mouse embryonic lung at the distal airways. Analysis of Hmga2-/- mice showed that Hmga2 is required for proper cell proliferation and distal epithelium differentiation during embryonic lung development. more...

(Submitter supplied) Epithelial organs including the lung are known to possess regenerative abilities through activation of endogenous stem cell populations but the molecular pathways regulating stem cell expansion and regeneration are not well understood. Here we show that Gata6 regulates the temporal appearance and number of bronchioalveolar stem cells (BASCs) in the lung leading to the precocious appearance of BASCs and concurrent loss in epithelial differentiation in Gata6 null lung epithelium. more...

(Submitter supplied) Alveologenesis is the culmination of lung development and involves the correct temporal and spatial signals to generate the delicate gas exchange interface. Using a novel Wnt signaling reporter system, we have identified a Wnt-responsive alveolar epithelial sublineage arising during alveologenesis called the axin2+ alveolar type 2 cell or AT2Aaxin2. The number of AT2Aaxin2 sublineage cells increases substantially during late lung development, revealing a wave of Wnt signaling during alveologenesis. more...

(Submitter supplied) The signaling crosstalk between the tracheal mesenchyme and epithelium has not been researched extensively leaving a substantial gap of knowledge in the mechanisms dictating embryonic development of the proximal airways by the adjacent mesenchyme. Recently, we have reported that embryos lacking mesenchymal expression of Sox9 did not develop tracheal cartilage rings and showed aberrant differentiation of the tracheal epithelium. more...

(Submitter supplied) Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal disease characterized by late diagnosis and treatment resistance. Recurrent genetic alterations in defined genes in association with perturbations of developmental cell signaling pathways have been associated with PDAC development and progression. Here, we show that GATA6 contributes to pancreatic carcinogenesis during the temporal progression of pancreatic intraepithelial neoplasia by virtue of Wnt pathway activation. more...

(Submitter supplied) Wnt signaling plays a pivotal role in colorectal cancer. Intrinsic activation of Wnt by mutational events, such as mutations in the tumor suppressor gene APC, represents the most frequent initiating event in this disease background. Long truncated versions of APC retain partial functionality, which leads to a sub-maximal, “just right” activation state of Wnt signaling supposed to be beneficial for disease initiation. more...

(Submitter supplied) ShhCre;Mst1/2flx/flx (Mst1/2 D/D) mice were generated to conditionally delete Mst1 and Mst2 from epithelial progenitors during lung morphogenesis. Lungs from E18.5 control and Mst1/2 D/D mice were mechanically and enzymatically dissociated to generate single cell suspension. Epcam(+) cells were isolated using magnetic microbeads. Microarray analysis of mRNAs isolated from Epcam(+) epithelial cells from E18.5 control and Mst1/2 D/D mice was performed to identify transcriptional changes following deletion of the mammalian Hippo kinases (Mst1 and Mst2) from the embryonic lung.

(Submitter supplied) Although mutations in Kras are present in 21% of lung tumors, there is a high level of heterogeneity in phenotype and outcomes amongst lung cancer patients suggesting the importance of other pathways. Wnt/β-catenin signaling is a known oncogenic pathway that plays a well defined role in colon and skin cancer but its role in lung cancer remains unclear. We show that activation of Wnt/β-catenin in the bronchiolar epithelium of the adult lung does not promote tumor development by itself. more...

(Submitter supplied) Mouse haematopoietic stem cells (HSCs) undergo a post-natal transition in several properties, including a marked reduction in their self-renewal activity. We now show that the developmentally timed change in this key function of HSCs is associated with their decreased expression of Lin28b and an accompanying increase in their let-7 microRNA levels. Lentivirus(LV)-mediated overexpression of Lin28 in adult HSCs elevates their self-renewal activity in transplanted irradiated hosts, as does overexpression of Hmga2, a well-established let-7 target that is upregulated in fetal HSCs. more...

(Submitter supplied) Wnt ligands oligomerize Frizzled (Fzd) and Lrp5/6 receptors to control the specification and activity of stem cells in many species. How Wnt is selectively activated in different stem cell populations, often within the same organ, is not understood. In lung alveoli, wherein Wnt-dependent epithelial and stromal progenitors are intermingled, we show that distinct Wnt receptors are expressed by epithelial (Fzd5/6), endothelial (Fzd4), and stromal (Fzd1) cells. more...
