Baicalein Inhibits αα-Melanocyte-stimulating Hormonestimulated Melanogenesis via p38 Mitogen-activated Protein Kinase Pathway in B16F10 Mouse Melanoma Cells

Oh MC, Madushan Fernando PDS, Piao MJ, Kang KA, akmini Herath HMU, Hyun JW

Excessive UVB exposure causes development of both malignant and non-malignant melanoma via the secretion of α-melanocyte-stimulating hormone (α-MSH). We investigated whether baicalein (5,6,7-trihydroxyflavone) could inhibit α-MSH-stimulated melanogenesis. Baicalein prevented UVB-...

Natural Compound Shikonin Induces Apoptosis and Attenuates Epithelial to Mesenchymal Transition in Radiation-Resistant Human Colon Cancer Cells

Shilnikova K, Piao MJ, Kang KA, Madushan Fernando PDS, Lakmini Herath HMU, Cho SJ, Hyun JW

Radiation resistance represents an imperative obstacle in the treatment of patients with colorectal cancer, which remains difficult to overcome. Here, we explored the anti-proliferative and migration-inhibiting properties of the natural...

The Endoplasmic Reticulum Stress Response Mediates Shikonin-Induced Apoptosis of 5-Fluorouracil–Resistant Colorectal Cancer Cells

Piao MJ, Han X, Kang KA, Madushan Fernando PDS, Lakmini Herath HMU, Hyun JW

Resistance to chemotherapeutic drugs is a significant problem in the treatment of colorectal cancer, resulting in low response rates and decreased survival. Recent studies have shown that shikonin, a naphthoquinone...

Phloroglucinol Attenuates Ultraviolet B-Induced 8-Oxoguanine Formation in Human HaCaT Keratinocytes through Akt and ErkMediated Nrf2/Ogg1 Signaling Pathways

Piao MJ, Kim KC, Kang KA, Madushan Fernando PDS, Lakmini Herath HMU, Hyun JW

Ultraviolet B (UVB) radiation causes DNA base modifications. One of these changes leads to the generation of 8-oxoguanine (8-oxoG) due to oxidative stress. In human skin, this modification may induce...
