NBR2 (Neighbor Of BRCA1 LncRNA)

NBR2 is highly expressed in T2DM patients and has potential value in T2DM diagnosis. NBR2 can participate in the regulation of pancreatic β-cell function by modulating miR-646.

Eupatilin exerts a reliable inhibitory effect on osteosarcoma cells through the NBR2/miR-129-5p/FKBP11 regulatory axis. Exosomes can effectively carry both eupatilin and miR-129-5p, enhancing their therapeutic efficacy.

The aim of this study was to investigate the link between starvation and lncRNAs by evaluating changes in autophagy-related proteins, cell proliferation and other biological processes. Together, these studies provide strategies for the early screening of breast cancer and suggest that starvation therapy can be used as a new approach for the treatment of cancer.

Moreover, NBR2 overexpression mitigated the enhancing effects of MWCNT-exposed macrophages on breast cancer metastasis. This study uncovered the molecular mechanisms underlying breast cancer metastasis induced by MWCNT exposure.

We identified eleven lncRNAs that were specifically downregulated in HGSC. Of these, CBR3-AS1, NBR2, and ADAMTS9-AS2 had unique functions in the malignant behaviors of HGSC.

Quantitative reverse transcriptase-polymerase chain reaction was used to evaluate the expression of miR-19a, and western blotting was used to determine the expression levels of tumor necrosis factor-α, human leukocyte antigen-DR, arginase-1, CD163, CD206, interleukin-4, AMP-activated protein kinase (AMPK), p-AMPK, hypoxia-inducible factor-1α (HIF-1α), protein kinase B (AKT), p-AKT, mechanistic target of rapamycin (mTOR), and p-mTOR in TAMs...LncRNA NBR2 was verified to target miR-19a in macrophages according to the results of the luciferase assay. Collectively, lncRNA NBR2 may suppress the progression of CRC by downregulating miR-19a to regulate M2 macrophage polarization.

DLC1 was the target gene of miR-561-5p and the protein expression of DLC1 was regulated by the NBR2/miR-561-5p axis. Collectively, NBR2/miR-561-5p/DLC1 axis inhibits the development of MM by activating the AMPK/mTOR pathway to repress glycolysis.

Next, the protein level of activation of adenosine monophosphate- activated protein kinase and the rapamycin kinase (mTOR) signalling pathway-associated molecules was evaluated by western blotting...Further mechanistic investigation showed that the down-regulation of NBR2 abolished the modulatory effects of C-PC on the AMPK/mTOR signalling pathway. In conclusion, C-PC inhibits H292 cell growth by enhancing the NBR2/AMPK signalling pathway.
