Analyses of our microRNA (miRNA) expression signature combined with The Cancer Genome Atlas (TCGA) data revealed that both strands of pre- (, the guide strand, and , the passenger strand) are significantly downregulated in lung adenocarcinoma (LUAD) clinical specimens. Functional analyses of LUAD cells ectopically expressing showed significant suppression of their aggressiveness (e.g.
View Article and Find Full Text PDFOsimertinib has demonstrated efficacy as the first- and second-line treatment for advanced non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) gene mutations. However, EGFR-mutant NSCLC cells often acquire resistance to osimertinib. V-Raf murine sarcoma viral oncogene homolog B1 (BRAF) mutation (BRAF V600E) was detected in a re-biopsy (LC-SCRUM-TRY testing) of a patient with advanced lung adenocarcinoma who was resistant to osimertinib treatment.

The analysis of our miRNA signature of LUAD revealed that both strands of pre- ( and ) were downregulated in LUAD tissues. Ectopic expression of both miRNAs induced cell cycle arrest in LUAD cells, suggesting both strands of miRNAs derived from pre- were tumor suppressive.

Extraocular pigmented lesions have been reported. We report that two patients with BDUMP presented with non-ocular pigmented lesions.

He was given a diagnosis of uveitis and treated with oral corticosteroids; however, his visual disturbance did not improve and he was admitted to our hospital. A chest CT scan showed a pulmonary nodule in the upper lobe of the right lung, and right hilar and mediastinal lymphadenopathy.
