| Abstract | Background Cryptorchidism is one of the most common reproductive abnormalities in rams, which seriously harms the reproductive capacity of rams and causes significant economic losses to the sheep industry. However, there are few studies elucidating its hereditary predisposition in sheep. Results In the present study, the transcriptome and proteome of the cryptic (CT) and contralateral (CLT) testis from four unilaterally cryptorchid rams, and the normal testis (NT) from four healthy rams were analyzed using RNA-seq and TMT-based proteomics, respectively. A total of 10,357, 10,175, and 132 differentially expressed genes (DEGs) were identified between CT vs. CLT, CT vs. NT, and CLT vs. NT. Venn diagram showed that 9744 DEGs (5499 up-regulated and 4245 down-regulated) shared in CT vs. CLT and CT vs. NT. Functional enrichment analysis revealed that 5499 up-regulated DEGs were mainly involved in regulation of programmed cell death and metabolic process, while 4245 down-regulated DEGs were closely related to reproductive process, such as spermatogenesis, sexual reproduction, reproduction and male gamete generation. Furthermore, 325 overlapped genes (114 up-regulated and 211 down-regulated) between DEGs and DAPs that shared the same regulatory status were identified by combining transcriptomics and proteomics. Ten genes, including AKAP4, AKAP3, FSIP2, HSPA1L, HSPA4L, TUBB, TXNRD2, CDC42, PGK1 and HSPA1A, were identified as candidate key genes related to unilateral cryptorchidism. Conclusion Our results revealed that both gene and protein expression in the cryptic testis of unilateral cryptorchid rams is massively altered. Bioinformatics analysis unveiled several candidate genes and signaling pathways potentially involved in unilateral cryptorchidism. These findings provide new insights into the molecular mechanism underlying spermatogenesis failure caused by cryptorchidism. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
