research A novel control of human keratin expression: cannabinoid receptor 1-mediated signaling down-regulates the expression of keratins K6 and K16 in human keratinocytesin vitroandin situ

66 citations , February 2013 in “PeerJ”

This study found that CB1 activation by a specific agonist led to decreased expression of keratins K6 and K16 in human skin and inhibited keratinocyte proliferation, suggesting potential for cannabinoid receptors in psoriasis management.

research Expression of keratins K6 and K16 in regenerating mouse epidermis is less restricted by cell replication than the expression of K1 and K10.

13 citations , July 1994 in “PubMed”

This study found that TPA treatment induced expression of keratins K6 and K16 in mouse epidermis, with K6 expressed across all cell layers and K16 only in post-mitotic cells.

research Peer Review #2 of "A novel control of human keratin expression: cannabinoid receptor 1-mediated signaling down-regulates the expression of keratins K6 and K16 in human keratinocytes in vitro and in situ (v0.1)"

February 2013

This study found that activating cannabinoid receptor 1 reduces the expression of keratins K6 and K16 in human keratinocytes, suggesting potential implications for psoriasis management.

research Peer Review #1 of "A novel control of human keratin expression: cannabinoid receptor 1-mediated signaling down-regulates the expression of keratins K6 and K16 in human keratinocytes in vitro and in situ (v0.1)"

February 2013

This study found that CB1 receptor activation reduced keratin K6 and K16 expression in human keratinocytes in vitro and in situ, suggesting potential relevance for both psoriasis management and wound healing.

research Keratin expression in the normal nail unit: markers of regional differentiation

119 citations , January 2000 in “British Journal of Dermatology”

This study found that keratin expression patterns vary within nail unit structures, with the nail matrix uniquely expressing the acidic hair-type keratin Ha1.
