RNA-seq of gubernaculum and testis from wild-type, cetacean INSL3 knock-in, and INSL3 knockout mice across developmental stages

This dataset contains high-throughput RNA sequencing (RNA-seq) data generated from gubernaculum and testis samples of wild-type (WT), cetacean INSL3 knock-in (KI), and INSL3 knockout (KO) mice at selected postnatal developmental stages. The purpose of the study was to investigate the molecular consequences of replacing the endogenous mouse Insl3 coding sequence with the cetacean INSL3 ortholog, and to compare transcriptomic profiles among WT, KI, and KO mice to elucidate the functional role of INSL3 in testicular descent and cryptorchidism. RNA-seq was performed on gubernaculum tissue at postnatal day 8 (P8) and testis tissue at P8, P23, and P40 (with some groups excluded due to degeneration or non-specific damage). The dataset supports integrative analyses of developmental stage–specific and genotype–specific gene expression changes in reproductive tissues.
