“MicroRNAs (miRNA) are small-non coding RNAs endowed with great regulatory power, thus playing key roles not only in almost all physiological pathways, but also in the pathogenesis of several diseases. Surprisingly, genomic distribution analysis revealed the highest density of miRNA sequences on the X chromosome; this evolutionary conserved mammalian feature equips females with a larger miRNA machinery than males. However, miRNAs contribution to some X-related conditions, properties or functions is still poorly explored. With the aim to support and focus research in the field, this review analyzes the literature and databases about X-linked miRNAs, trying to understand how miRNAs could contribute to emerging gender-biased functions and pathological mechanisms, such as immunity and cancer. A fine map of miRNA sequences on the X chromosome is reported, and their known functions are discussed; in addition, bioinformatics functional analyses of the whole X-linked miRNA targetome (predicted and validated) were performed. The emerging scenario points to different gaps in the knowledge that should be filled with future experimental investigations, also in terms of possible implications and pathological perspectives for X chromosome aneuploidy syndromes, such as Turner and Klinefelter syndromes.”







My favorite part of serving AXYS as your Executive Director is getting to know our community. In mid August I was in Michigan visiting my family and had the pleasure to meet 7 families in our community.
On Friday, Wendy and her son John, a 30-year-old with XXY, drove 75 miles to meet me, and Dan and Sonya who have a son with XXY. Wendy offered to share brochures with doctors in Grand Rapids. Thank you Wendy!!
When KS&A was formed in 1989 by an Ann Landers letter that Melissa Aylstock had written, the organization took off from there. Melissa was very welcoming to new families, and to men newly diagnosed with KS. She ran the organization practically by herself. While her husband assisted, she was the webmaster and handled listserv duties when that started in 1997.
So I got involved immediately just after returning from the 1996 national conference and wore a lot of hats and did a lot of work for her and the organization. I presented two sessions at the 1997 conference, as well as at the 1998 conference. I co-chaired the national conference in Baltimore in 1999 and planned a good conference with added bonuses as we were celebrating the 10th anniversary of the organization.
