Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

Molecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Probing RNA Structure by Lead Cleavage [PDF]

Current Protocols in Nucleic Acid Chemistry, 2000
AbstractLead cleavage causes a transesterification reaction that breaks the 5′,3′‐phosphodiester backbone of RNA, leaving a 2′,3′‐cyclic phosphate and a 5′‐hydroxyl. Since the efficiency of the reaction at the 2′‐hydroxyl is related to steric and chemical constraints on particular 2′‐hydroxyls embedded in the RNA, this reaction can be used to examine ...

Role of RNA binding protein HuR in antagonizing the microRNA-mediated repression [PDF]

, 2011
MicroRNAs (miRNAs) are ~21-nt-long non-coding RNAs regulating gene expression in eukaryotes. In metazoa, miRNAs control gene expression by base-pairing to target mRNAs, bringing about their translational repression and/or deadenylation resulting in mRNA ...

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Preferential cleavage of the coronavirus defective viral genome by cellular endoribonuclease with characteristics of RNase L

Virology Journal
In testing whether coronavirus defective viral genome 12.7 (DVG12.7) with transcription regulating sequence (TRS) can synthesize subgenomic mRNA (sgmRNA) in coronavirus-infected cells, it was unexpectedly found by Northern blot assay that not only sgmRNA

Re-characterization of hammerhead ribozymes as molecular tools for intermolecular RNA cleavage

, 2017
A new guideline for the construction of hammerhead ribozymes to achieve trans-cleavage of a single-stranded RNA molecule was developed. The sequence rule of the HHRz cleavage site was highly recommended to be "DWH" with an optimal binding arm length of 8-

A hepatitis C virus cis-acting replication element forms a long-range RNA-RNA interaction with upstream RNA sequences in NS5B [PDF]

, 2008
The genome of hepatitis C virus (HCV) contains cis-acting replication elements (CREs) comprised of RNA stem-loop structures located in both the 5' and 3' non-coding regions (NCR), and in the NS5B coding sequence.

PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Preparation of Small RNAs Using Rolling Circle Transcription and Site-Specific RNA Disconnection

Molecular Therapy: Nucleic Acids, 2015
A facile and robust RNA preparation protocol was developed by combining rolling circle transcription (RCT) with RNA cleavage by RNase H. Circular DNA with a complementary sequence was used as the template for promoter-free transcription.
