“…All of them increase significantly at 3 dpf and 7 dpf. At 0.5 dpf upregulation of three genes can probably be attributed to maternal influences [88][89][90][91]. Both the WSS-AVC and WSS-OFT increase significantly at 6 dpf compared with 3 dpf (figure 8b).…”

The progression of cardiac gene expression–wall shear stress (WSS) interplay is critical to identifying developmental defects during cardiovascular morphogenesis. However, mechano-genetics from the embryonic to larval stages are poorly understood in vertebrates. We quantified peak WSS in the heart and tail vessels of Japanese medaka from 3 days post fertilization (dpf) to 14 dpf using in vivo micro-particle image velocimetry flow measurements, and in parallel analysed the expression of five cardiac genes ( fgf8 , hoxb6b , bmp4 , nkx2.5 , smyd1 ). Here, we report that WSS in the atrioventricular canal (AVC), ventricular outflow tract (OFT), and the caudal vessels in medaka peak with inflection points at 6 dpf and 10–11 dpf instead of a monotonic trend. Retrograde flows are captured at the AVC and OFT of the medaka heart for the first time. In addition, all genes were upregulated at 3 dpf and 7 dpf, indicating a possible correlation between the two, with the cardiac gene upregulation preceding WSS increase in order to facilitate cardiac wall remodelling.

The present study assessed the effects of maternal copper or cadmium exposure in a live-bearing fish. After a 10-d exposure to background levels (control) or 0.15 μM copper or cadmium, gravid females were transferred to clean water. Once a female gave birth, the authors analyzed her newborn offspring for lipid peroxidation, elemental composition (copper, cadmium, and calcium), and metal tolerance. The authors raised other offspring until sexual maturity and analyzed their growth rate, incidence of abnormalities, and sex ratio. Their earlier research, using the same species and exposure design, demonstrated that cadmium and copper were transferred from gravid females to their offspring. The present study showed that offspring of copper-exposed females had a reduced size at birth, developmental abnormalities, elevated tissue cadmium levels, and reduced tissue calcium levels. Offspring of cadmium-exposed females had elevated levels of lipid peroxidation, developmental abnormalities, and lower tissue levels of both copper and calcium. No effects were detected with respect to offsprings' growth rate or sex ratio. Offspring of metal-exposed fish had a reduced tolerance to the metal that their female parent had been exposed to, and the tolerance showed an inverse relationship to the tissue metal level in the offspring. The latter indicates that the reduced tolerance was the result of an increased body burden prior to the tolerance quantification. The present study constitutes the first report in live-bearing fishes showing that maternal metal exposure has a wide range of negative impacts on the offspring.
