Therapeutic Effects of Makino Against Atopic Dermatitis-Like Skin Inflammation Through the JAK2/STAT Signaling Pathway.

Atopic dermatitis (AD), a chronic inflammatory skin condition, is a common allergic disorder. The human skin, the largest organ, serves as the first barrier in protecting the body against various external threats. Human epidermal keratinocytes (HEKs) in the epidermal layer and human dermal fibroblasts (HDFs) in the dermis of the skin are implicated in AD-associated skin inflammation through the secretion of diverse inflammatory mediators, including chemokines.

Nakai Extract Attenuates Atopic Dermatitis-like Symptoms by Regulating Skin Barrier Factors and Inhibiting the JAK/STAT Pathway.

Atopic dermatitis is caused by various factors, including complex interactions between immune responses and imbalances in T helper cells.

Bruton's agammaglobulinemia tyrosine kinase (Btk) regulates TPA‑induced breast cancer cell invasion via PLCγ2/PKCβ/NF‑κB/AP‑1‑dependent matrix metalloproteinase‑9 activation.

Bruton's agammaglobulinemia tyrosine kinase (BTK) is an important cytoplasmic tyrosine kinase involved in B‑lymphocyte development, differentiation, and signaling. Activated protein kinase C (PKC), in turn, induces the activation of mitogen‑activated protein kinase (MAPK) signaling, which promotes cell proliferation, viability, apoptosis, and metastasis. This effect is associated with nuclear factor‑κB (NF‑κB) activation, suggesting an anti‑metastatic effect of BTK inhibitors on MCF‑7 cells that leads to the downregulation of matrix metalloproteinase (MMP)‑9 expression.

Casein kinase 2 (CK2) is a serine/threonine protein kinase that has been considered to represent an important factor in mammary tumorigenesis. Increased expression of matrix metalloproteinase‑9 (MMP‑9) via nuclear factor‑κB (NF‑κB) activation has been demonstrated to promote breast cancer cell invasion. In the present study, the involvement of CK2 in protein kinase C (PKC) induced cell invasion in MCF‑7 breast cancer cells was investigated as well as the underlying molecular mechanisms.

Reversine inhibits MMP-1 and MMP-3 expressions by suppressing of ROS/MAPK/AP-1 activation in UV-stimulated human keratinocytes and dermal fibroblasts.

UVB has been shown to stimulate the generation of reactive oxygen species (ROS), which subsequently results in the activation of various intracellular signalling pathways and transcription factors (AP-1, NF-κB). These transcription factors are regulated by MAPKs, which increase cytokine and MMP expression. We examined the preventive effects of reversine on MMP-1 and MMP-3 expressions in NHEKs and NHDFs exposed to UVB irradiation.
