Ooplasmic transfer (01) has been used in basic mouse research for studying lhe segregation of mtDNA, as well as in human assisted reproduction for improving embryo development in cases of persistent developmental failure. Using cattle as a large-animal model, we demonstrate that lhe moderate amount of mitochondria introduced by OT is transmitted to lhe offspring's oocytes; e.g., modifies lhe germ fine. The danar mtDNA was detectable in 25% and 65% of oocytes collected from two females. Its high variation in heteroplasmic oocytes, ranging from 1.1% to 33.5% and from 0.4% to 15.5%, can be explained by random genetic drift in lhe female germ line. Centrifugation-mediated enrichment of mitochondria il1 lhe pole zone of lhe recipient zygote's ooplasm and its substitution by danar ooplasm led to elevated proportions of danar mtDNA in reconstructed zygotes compared with zygotes produced by standard OT (23.6% :!: 9.6% versus 12.1% :!: 4.5%; P <0.0001). We also characterized lhe proliferation of mitochondria from lhe OT parents-the recipient zygote (Bos primigenius taurus type) and lhe danar ooplasm (B. primigenius indicus type). Regression analysis performed for 57 tissue samples collected from lhe seven OT fetuses at different points during fetal development found a decreasing proportion of donor mt DNA (r2=0.78). This indicates a preferred proliferation of recipient of the OT recipeint expressinf a B. primigenius indicus phenotype. |

Abstract: Perfluorooctanesulfonic acid (PFOS) is a manmade chemical with several industrial applications and also a potential byproduct of many other per- and polyfluorinated substances (PFAS) in the environment. Due to the gathered evidence on its environmental persistence, long-range transport, toxicity, and bioaccumulative and biomagnifying properties, PFOS, its salts and perfluorooctane sulfonyl fluoride (PFOSF), were listed for global restriction under the Stockholm Convention on Persistent Organic Pollutants in 2009. Nevertheless, Brazil has granted an acceptable purpose exemption for using PFOSF to produce sulfluramid (EtFOSA) and to apply it as insecticide to control leaf-cutting ants of the genus Atta and Acromyrmex. Previous studies have pointed out EtFOSA as a precursor of PFOS in the environment, including in soils. Therefore, we aimed to confirm the role of EtFOSA in PFOS formation in soils representing areas where sulfluramid-based ant baits are used. A biodegradation assay was carried out by applying technical EtFOSA in triplicate samples of ultisol (PV) and oxisol (LVd) and measuring the contents of EtFOSA, perfluorooctane sulfonamide acetic acid (FOSAA), perfluorooctane sulfonamide (FOSA), and PFOS at seven moments (0, 3, 7, 15, 30, 60, and 120 days). The monitored byproducts started being noticed on the 15th day. After 120 days, PFOS yields were 30% for both soils, whereas FOSA yields were 46% (PV soil) and 42% (LVd soil) and FOSAA yields were 6% (PV soil) and 3% (LVd soil). It can be expected that FOSAA and FOSA contents will eventually be converted into PFOS in the environment and that the presence of plants could boost PFOS formation. Therefore, the ongoing extensive and intensive use of sulfluramid-based ant baits pose a considerable source of PFOS to the environment.
