Does microRNA miR-7 contribute to the control of Drosophila wing growth?
The results from this work reveal, for the first time, that miR-7 functions to regulate Drosophila wing growth by controlling cell cycle phasing and cell mass through its regulation of the expression of dacapo and the Notch signaling pathway.
We interpret the findings of our study as the onset of pulmonary hypertension resulting from repetitive pulmonary vasoconstriction together with severe hypoxia during apnea diving. We conclude that regular competitive apnea diving over a period of>2 to 3 years might carry a chronic cardiopulmonary risk that may lead from early functional changes to manifestation of pulmonary hypertension.
