In addition, although our data showed MOTS‐c regulated post‐translational modifications of the LARS1 protein and did not affect its mRNA levels, we also found that the mRNA levels of LARS1 varied in ovarian cancers, suggesting that the regulation of LARS1 may not only occur at the post‐translational level, but also at a transcriptional or post‐transcriptional level. This evidence concerns the gene MT-RNR1 and ovarian cancer.
