The Channel-Activating Protease CAP1/Prss8 Is Required for Placental Labyrinth Maturation

Friedrich Beermann, Simona Frateschi, Roch-Philippe Charles, Aline Dousse

The serine protease CAP1/Prss8 is crucial for skin barrier function, lung alveolar fluid clearance and has been unveiled as diagnostic marker for specific cancer types. Here, we show that a constitutive knockout of CAP1/Prss8 leads to embryonic lethality. ...

Early Fate Choice Determines in vivo Engraftment and in vitro Behavior of Epidermal Stem Cells

François Gorostidi

Regenerative medicine aims at using stem cells to restore or establish lost, damaged, diseased, or aging tissues and organs function. The transplantation of cultured epidermal autograft (CEA) has saved the lives of many burned patients over the last 30 yea ...

Asymmetric Cell Division in the Skin

Wan-Hung Fan

An asymmetric cell division (ACD) is defined as a division that gives rise to two daughter cells with different fates. It is the most common type of division during development. Analogous to Drosophila neuroblasts, proteins involved in ACD such as Insc and ...

The Role of LEKTI in the Fate Determination of Keratinocyte Stem Cells

Alessandro Wataru Amici

SPINK5 (serine protease inhibitor Kazal-type 5) encodes the proteinase inhibitor LEKTI (lympho-epithelial Kazal-type related inhibitor). In skin, LEKTI expression is restricted to the stratum granulosum of the epidermis and the inner root sheath of hair fo ...

PAR2 absence completely rescues inflammation and ichthyosis caused by altered CAP1/Prss8 expression in mouse skin

Friedrich Beermann, Simona Frateschi, Anne Wilson, Roch-Philippe Charles

Altered serine protease activity is associated with skin disorders in humans and in mice. The serine protease channel-activating protease-1 (CAP1; also termed protease serine S1 family member 8 (Prss8)) is important for epidermal homeostasis and is thus in ...

RhoV, a Potential Notch Target Gene in Murine Skin, Does not Play an Essential Role in Epidermis Development and Homeostasis

April Bezdek Pomey

The evolutionarily conserved Notch signaling cascade plays a pivotal role in the regulation of many fundamental processes such as stem cell maintenance, proliferation, and differentiation. Recently, we aimed to identify downstream target genes regulated by ...

Identification of epidermal pdx1 expression discloses different roles of notch1 and notch2 in murine kras-induced skin carcinogenesis in vivo

Freddy Radtke

BACKGROUND: The Ras and Notch signaling pathways are frequently activated during development to control many diverse cellular processes and are often dysregulated during tumorigenesis. To study the role of Notch and oncogenic Kras signaling in a progenitor ...
