SPANX control of Lamin A/C modulates nuclear architecture and promotes melanoma growth


ABSTRACT: Purpose: To investigate mechanisms underlying SPANX knockdown phenotypes, we monitored changes in gene expression profiles in A375 melanoma cells subjected to SPANX KD (RNA-Seq). Methods: RNASeq Libraries were prepared from isolated total RNA using the QuantSeq 3' mRNA-Seq Library Prep Kit FWD for Illumina from Lexogen, (Vienna, Austria). Barcoded libraries were pooled and single end sequenced (1X75) on the Illumina NextSeq 500 using the High output V2.5 kit (Illumina Inc., San Diego CA). Raw data FASTQ files were generated by standstard illumina base calling pipeline and stored in illumina cloud service BaseSpace. Reads were aligned with the STASR aligner. Analyses of differentially expressed genes (DEGs) were subsequently performed using a negative binomial test method (edgeR)10 implemented using SARTools R Package Results: Of 609 genes deregulated by both shRNA, 454 were upregulated and 123 were downregulated. Networks associated with cell division were downregulated following SPANX KD, while those associated with 3-phosphoinositide biosynthesis were upregulated. Notably, IPA analysis identified the cell cycle as the primary pathway deregulated, and further analysis using the reactome database revealed that most of those genes were associated with the G1/S transition.
