    Significance of KLK7 expression, polymorphisms, and function in sheep horn growth by Mingzhu Shan, Hao Li, Xinyue Li, Guoqing Zhang, Jianxin Shi, Pingjie Feng, Lisheng Zhou, Zhangyuan Pan, Mingxing Chu

    Published 2025-01-01
    “…Conclusion Our results demonstrate that KLK7 was highly expressed in soft horn and skin tissues, and its expression was significantly higher in small-horned sheep than it was in large-horned sheep, suggesting that KLK7 may have an inhibitory effect on horn growth. By comparing the amino acid sequence of KLK7 with KLK7 sequences in other species, we discovered eight amino acids at specific positions in the KLK7 protein sequence that may have regulatory functions in determining the size of horns in ruminant animals. …”

    Published 2025-01-01
    “…Results‍ ‍① The results of scRNA-seq showed that in the two set clusters of prospermatogonia, the prospermatogonia that further specifies to generate SSCs had enriched genes that are associated with cell proliferation. ② Germ cell proliferation assay indicated that the average ratio of Ki67+ germ cells in the testicular cross-section of the cKO mice was significantly higher than that of the control mice at P2.5 [(46.10±6.21)% vs (11.22±3.27)%, P<0.01]. ③ Flow cytometry revealed that, among the brightest community of ID4-GFP cells, the percentage of the cells at S phase was obviously higher in the testicular cells derived from the cKO mice when compared to the control mice at P2.5 [(12.05±1.22)% vs (5.05±1.46)%, P<0.05].④ TUNEL staining displayed that cell apoptosis was detected in the testicular cross-section of cKO mice rather than that of the control mice. ⑤ The results of SSCs specification exploration showed that statistical difference was observed in the percentage of cytoplasmic FOXO1 in the testicular cross-section between the control and cKO mice [(20.57±2.15)% vs (45.08±2.45)%,P<0.01]. …”
