Expression of AID in malignant melanoma with BRAF(V600E) mutation.

BRAF-activating somatic mutations often exist in malignant melanoma. The underlying molecular mechanism of somatic BRAF mutation inductions remained to be clear. Activation-induced cytidine deaminase (AID), a member of a cytidine deaminase family, and APOBEC3B induce somatic mutations and recently have been indicated to be involved in the pathomechanism of several kinds of cancers.

What determines human body odour?

Human body odour and earwax type are genetically dependent on a single-nucleotide polymorphism (SNP) located in the ABCC11 gene. So far, it still remains to be clear how SNP in the ABCC11 gene is associated with human malodour. In a recent issue of Experimental Dermatology, Baumann et al.

Galectin-7, induced by cis-urocanic acid and ultraviolet B irradiation, down-modulates cytokine production by T lymphocytes.

Urocanic acid (UCA) is an epidermal chromophore that undergoes trans to cis isomerization after UVB irradiation. cis-UCA is a potent inhibitor of cutaneous acquired immunity. The aim of this study was to explore the genes, which are upregulated by cis-UCA in normal human epidermal keratinocytes (NHEK) and investigated its role in vitro using human T-lymphocyte cell line, Jurkat cells.

Combination of skin-directed therapy and oral etoposide for smoldering adult T-cell leukemia/lymphoma with skin involvement.

Approximately 50% of patients with adult T-cell leukemia/lymphoma (ATLL) have skin involvement, and the smoldering, skin lesion-bearing cases are often treated with various skin-directed therapies, such as phototherapy and radiation therapy. Daily oral administration of etoposide plus prednisolone (EP) is also used for smoldering-type ATLL. However, it remains unclear whether these therapies improve patients' survival.

[Wheat dependent exercise induced anaphylaxis possibly sensitized by the hydrolyzed wheat proteins in a facial cleansing soap].

There are increasing cases of wheat dependent exercise-induced anaphylaxis (WDEIA) with transcutaneous or transmucosal sensitization. Hydrolyzed wheat included in a certain brand of soap was identified as a cause of sensitization. The useful clues to detect this disorder consist of the patient's past usage of a soap containing hydrolyzed wheat, the appearance of cutaneous or mucosal symptoms after the intake of wheat or washing with this soap, and a high level of specific IgE for wheat gluten.
