More than half in number of the freshly laid eggs

More than half in number of the freshly-laid eggs (n=90) obtained from control (c355-GAL4/+) female flies after they have been crossed to males expressing dj-GFP (Fig. 1C and G) proved to be successfully fertilized, with GFP-tagged sperm being readily detected in their cytoplasm. Similarly, a 67% mean value of laid eggs (n=105), derived from control female flies mated with protamineB-eGFP; dj-GFP transgene-carrying males, were also presented with GFP-tagged sperm (see, its coiled shape within the anterior region of the herein shown representative follicle) inside each fertilized egg׳s Birinapant (Fig. 1D and G). In contrast, GFP-tagged sperm could not be detected inside the cytoplasm of the freshly-laid s36-depleted eggs produced by female flies that have been inseminated either by dj-GFP (n=110; Fig. 1E and G) or by dj-GFP and protamineB-eGFP transgene-containing males (n=120; Fig. 1F and G). Interestingly, insemination (introduction of semen into the female animal), and not sperm penetration into the mature follicle, seems to represent a sufficient factor for triggering the ovulation process in D. melanogaster, since no statistically significant difference in the egg-deposition capacity could be observed between control and s36-targeted flies.

Data Fig. 1 showed that Axin2, Sfrp2, Sfrp4, Dkk1 and Dkk3 mRNA expression is present in the uterine epithelium and/or stromal cells. Progesterone treatment of neonatal mice suppresses endometrial gland development but has no effect on the expression of Wnt ligands: Wnt1, Wnt2, Wnt2b, Wnt3, Wnt3a, Wnt5b, Wnt7b, Wnt8a, Wnt8b, Wnt9a, Wnt9b, Wnt10a and Wnt10b (Fig. 2).

Data We tested a hypothesis that APOBEC2 may be an important mediator in the “self-renewal” functions of satellite cells, namely in the re-establishment of quiescent status after activation and proliferation. in vitro experiments in mouse single-myofiber cultures prepared from APOBEC2-KO (A2KO) mice demonstrated a significant decrease in the population of Pax7(+) MyoD(−) quiescent satellite cells along with a complementary increase in Pax7(−) MyoD(+) early-differentiated myoblasts concerned in Ref. [1] (p<0.0005) (Fig. 1), supporting a possible insight that APOBEC2 regulates a competitive balance between two trajectories of proliferated myoblasts during muscle regeneration: a return to cell quiescence which re-establishes the satellite cell pool and their differentiation and fusion which results in myotube formation.
