| خلاصه مقاله | Introduction: Wilms tumor (WT) and rhabdoid tumor of the kidney
(RT) are respectively the most and less common types of pediatric
kidney tumors. Due to the presence of overlapping histologic patterns
and similar cell types across these tumors, their differential diagnosis
solely based on histologic study can be challenging. To this end, this
study aimed to apply machine learning and deep learning algorithms to
identify the most important mRNAs and microRNAs panels that can be
involved in the pathogenesis of the WT and RT.
Methods: The RNA transcripts including 1881 microRNA (miRNAs)
and 60,482 mRNAs obtained from 126 and 199 patients, respectively,
were downloaded from The Cancer Genome Atlas (TCGA) dataset. To
identify candidate features (mRNAs and miRNAs), graph and filter algorithms were used in feature selection. Then, a deep model was used
to classify the tumors. Finally, an association rule mining algorithm was
used for detecting the most significant mRNAs/ miRNAs involved in
the pathogenesis of the WT and RT.
Results: In the classification step, candidate miRNAs could classify the
WT and RT classes in train/test data with high accuracy (97% / 93%).
Candidate mRNAs could also classify the WT and RT classes in train/
test data with high accuracy (94% / 97%) and AUC ($0.95). The Association Rule Mining analysis could identify the Chromosome 19 open
reading frame 24 (C19orf24) and let-7a-2 as well as the RP1-3E10.2 and
miR-199b as first top transcripts in the WT and RT, respectively.
Conclusions: The employed framework can offer further insight into
the pathogenesis, diagnosis, prognosis, and therapeutic targets in pediatric kidney tumors. |
