    A population genetic test of selection at the molecular level (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-12-01
    Description: The role of natural selection in molecular evolution has been inferred primarily by rejection of null hypotheses based on neutral theory, rather than by acceptance of specific predictions based on selection. In this report, a population genetic test of a specific prediction for selection on DNA polymorphism is presented. Pyrethroid insecticide use constitutes an experiment for which form of selection and molecular target (voltage-gated sodium channels) are both known. As predicted, differential pyrethroid selection on tobacco budworm populations generated significant geographic heterogeneity in sodium channel marker allele frequencies, compared with arbitrary loci.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taylor, M F -- Shen, Y -- Kreitman, M E -- New York, N.Y. -- Science. 1995 Dec 1;270(5241):1497-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, Center for Insect Science, University of Arizona, Tucson 85721, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7491497" target="_blank"〉PubMed〈/a〉

    Gamma-secretase gene mutations in familial acne inversa (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-10-12
    Description: Acne inversa (AI), also known as hidradenitis suppurativa, is a chronic, recurrent, inflammatory disease of hair follicles that often runs in families. We studied six Chinese families with features of AI as well as additional skin lesions on back, face, nape, and waist and found independent loss-of-function mutations in PSENEN, PSEN1, or NCSTN, the genes encoding essential components of the gamma-secretase multiprotein complex. Our results identify the gamma-secretase component genes as the culprits for a subset of familial AI, implicate the gamma-secretase-Notch pathway in the molecular pathogenesis of AI, and demonstrate that familial AI can be an allelic disorder of early-onset familial Alzheimer's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Baoxi -- Yang, Wei -- Wen, Wen -- Sun, Jing -- Su, Bin -- Liu, Bo -- Ma, Donglai -- Lv, Dan -- Wen, Yaran -- Qu, Tao -- Chen, Min -- Sun, Miao -- Shen, Yan -- Zhang, Xue -- New York, N.Y. -- Science. 2010 Nov 19;330(6007):1065. doi: 10.1126/science.1196284.
