Profiling the role of m6A effectors in the regulation of pluripotent reprogramming.

The N-methyladenosine (mA) RNA modification plays essential roles in multiple biological processes, including stem cell fate determination. To explore the role of the m6A modification in pluripotent reprogramming, we used RNA-seq to map m6A effectors in human iPSCs, fibroblasts, and H9 ESCs, as well as in mouse ESCs and fibroblasts. By integrating the human and mouse RNA-seq data, we found that 19 m6A effectors were significantly upregulated in reprogramming.

Profiling mitochondria-polyribosome lncRNAs associated with pluripotency.

Pluripotent stem cells (PSCs) provide unlimited resources for regenerative medicine because of their potential for self-renewal and differentiation into many different cell types. The pluripotency of these PSCs is dynamically regulated at multiple cellular organelle levels. To delineate the factors that coordinate this inter-organelle crosstalk, we profiled those long non-coding RNAs (lncRNAs) that may participate in the regulation of multiple cellular organelles in PSCs.

HULC targets the IGF1R-PI3K-AKT axis in trans to promote breast cancer metastasis and cisplatin resistance.

Insulin-like growth factor I receptor (IGF1R) is frequently upregulated in breast cancer. Due to its intrinsic tyrosine kinase activity, aberrant activation of the IGF1R signaling axis may enhance tumor cell proliferation and cancer stemness, causing tumor relapse, metastasis and resistance to chemotherapy. We utilized a chromatin RNA in situ reverse transcription (CRIST) approach to characterize molecular factors that regulate the IGF1R network.

Nuclear-Encoded lncRNA Epigenetically Controls Metabolic Reprogramming in HCC Cells through the Mitophagy Pathway.

Mitochondrial dysfunction is a metabolic hallmark of cancer cells. In search of molecular factors involved in this dysregulation in hepatocellular carcinoma (HCC), we found that the nuclear-encoded long noncoding RNA (lncRNA) (metastasis-associated lung adenocarcinoma transcript 1) was aberrantly enriched in the mitochondria of hepatoma cells. Using RNA reverse transcription-associated trap sequencing (RAT-seq), we showed that interacted with multiple loci on mitochondrial DNA (mtDNA), including D-loop, , , and genes.

MicroRNA-124-3p affects proliferation, migration and apoptosis of bladder cancer cells through targeting AURKA.

Objective: The aim of this study was to establish the relationship between miR-124-3p and Aurora A kinase (AURKA) in bladder cancer (BC).

Methods: The expressions of miR-124-3p and AURKA in BC tissues and cell lines were detected using RT-PCR and western blot. BC cells were transfected with miR-124-3p mimics and AURKA siRNA.
