Carcinogenesis 2018 04;39(4):571-579

Korle Bu Teaching Hospital, Accra, Ghana.

Skin lighteners and hair relaxers, both common among women of African descent, have been suggested as possibly affecting breast cancer risk. In Accra and Kumasi, Ghana, we collected detailed information on usage patterns of both exposures among 1131 invasive breast cancer cases and 2106 population controls. Multivariate analyses estimated odds ratios (ORs) and 95% confidence intervals (CIs) after adjustment for breast cancer risk factors. Read More

Anti-Pigmentation Effects of Eight -Fermented Traditional Crude Herbal Extracts on Brown Guinea Pigs of Ultraviolet B-Induced Hyperpigmentation.

J Microbiol Biotechnol 2018 Mar;28(3):375-380

Department of Biotechnology, College of Natural Resources and Life Science, Dong-A University, Busan 49315, Republic of Korea.

We have previously found that mycelia culture broth of eight kinds of traditional herbal extracts fermented with (previously named as 8-HsPLCB) not only inhibited melanin and tyrosinase activity, but also reduced the contents of melanogenesis-related proteins, including tyrosinase and microphthalmia-associated transcription factor, in 3-isobutyl-1-methylxanthine-stimulated B16F0 melanoma cells. For a further study, the effect of 8-HsPLCB against skin pigmentation in brown guinea pigs with ultraviolet B (UVB)-induced hyperpigmentation was investigated. 8-HsPLCB (3%) and arbutin (2%) as positive controls were applied topically twice daily for 4 weeks to the hyperpigmented areas.

Neural Stem Cells and Its Derivatives as a New Material for Melanin Inhibition.

Int J Mol Sci 2017 Dec 22;19(1). Epub 2017 Dec 22.

School of Biosystem and Biomedical Science, College of Health Science, Korea University, 22 Gil Inchon-ro, Seongbuk-gu, Seoul 02855, Korea.

The pigment molecule, melanin, is produced from melanosomes of melanocytes through melanogenesis, which is a complex process involving a combination of chemical and enzymatically catalyzed reactions. The synthesis of melanin is primarily influenced by tyrosinase (TYR), which has attracted interest as a target molecule for the regulation of pigmentation or depigmentation in skin. Thus, direct inhibitors of TYR activity have been sought from various natural and synthetic materials. Read More
