Multiple myeloma (MM), the second most common hematologic malignancy, is an incurable disease characterized by the accumulation of malignant plasma cells within the bone marrow. Though great progresses have been made in understanding the mechanisms of MM, metabolic plasticity and drug resistance remain largely unknown. In this study, we found lncRNA Protein disulfide isomerase family A member 3 pseudogene 1 (PDIA3P) is highly expressed in MM and is associated with the survival rate of MM patients. PDIA3P regulates MM growth and drug resistance through Glucose 6-phosphate dehydrogenase (G6PD) and the pentose phosphate pathway (PPP)...

Purinergic signaling contributes to inflammatory and immune responses. The activation of the P2X purinoceptor 7 (P2X7) in satellite glial cells (SGCs) may be an essential component in the promotion of inflammation and neuropathic pain. Long non‑coding RNAs (lncRNAs) are involved in multiple physiological and pathological processes. The aim of the present study was to investigate the effects of a small interfering RNA for the lncRNA BC168687 on SGC P2X7 expression in a high glucose and high free fatty acids (HGHF) environment...

Adiponectin (AdipoQ) is an adipocyte-derived hormone with positive function on systemic glucose and lipid metabolism. Long noncoding RNA (lncRNA) is emerging as a vital regulator of adipogenesis. However, AdipoQ-related lncRNAs in lipid metabolism have not been explored. Here, AdipoQ antisense (AS) lncRNA was first identified, and we further found that it inhibited adipogenesis. The half-life of AdipoQ AS lncRNA was 10 h, whereas that of AdipoQ mRNA was 4 h. During adipogenic differentiation, AdipoQ AS lncRNA translocated from nucleus to cytoplasm...

Mammalian genomes encode a huge number of LncRNAs with unknown functions. This study determined the role and mechanism of a new LncRNA, LncRNA Suppressor of Hepatic Gluconeogenesis and Lipogenesis (LncSHGL), in regulating hepatic glucose/lipid metabolism. In the livers of obese mice and NAFLD patient, the expression levels of mouse LncSHGL and its human homologous LncRNA B4GALT1-AS1 were reduced. Hepatic LncSHGL restoration improved hyperglycemia, insulin resistance and steatosis in obese diabetic mice, whereas hepatic LncSHGL inhibition promoted fasting hyperglycemia and lipid deposition in normal mice...

Studies have shown that long noncoding ribonucleic acids (lncRNAs) play critical roles in multiple biologic processes. However, the Small Nucleolar RNA Host Gene 1 (SNHG1) function and underlying molecular mechanisms in ischemic stroke have not yet been reported. In the present study, we found that SNHG1 expression was remarkably increased both in isolated cerebral micro-vessels of a middle cerebral artery occlusion (MCAO) mice model, and in oxygen-glucose deprivation (OGD)-cultured mice brain micro-vascular endothelial cells (BMECs), meanwhile, the SNHG1 level was negatively correlated with miR-18a in MCAO mice...

Over-activated hepatic gluconeogenesis contributes to the pathogenesis of metabolic disorders, including type 2 diabetes. Precise control of hepatic gluconeogenesis thus is critical for maintaining whole-body metabolic homeostasis. Long non-coding RNAs (lncRNAs) have been shown to play key roles in diseases by regulating diverse biological processes, but the function of lncRNAs in maintaining normal physiology, particularly glucose homeostasis in the liver, remains largely unexplored. We identified a novel liver-enriched long non-coding RNA, Gm10768, and examined its expression patterns under pathophysiological conditions...

Long non-coding RNA (lncRNA) maternally expressed gene 3 (MEG3) has been demonstrated as an important regulator in diverse human cancers. However, its function and regulatory mechanism in ischemic stroke remains largely unknown. Here, we report that MEG3 is physically associated with microRNA-21 (miR-21), while miR-21 is downregulated following ischemia in the ischemic core in vitro and in vivo, which is opposite to MEG3. Besides, overexpression of miR-21 protects oxygen-glucose deprivation and reoxygenation (OGD/R)-induced apoptotic cell death...

Extensive changes of neuronal transcriptome occur post ischemic stroke and during the following reperfusion. Although numerous studies focused on transcriptome changes of mRNAs associated with ischemic stroke, little is known about whether and how long non-coding RNAs (lncRNAs), which play critical roles in cellular homeostasis, are involved in this process. In this study, we performed high throughput screening to analyze expression changes of lncRNAs in primarily cultured hippocampal neurons under an oxygen-glucose deprivation/reperfusion (OGD/R) condition at 0h, 6 h, 12 h, and 18 h, respectively...

Pyroptosis is a type of programmed cell death, which has been associated with multiple inflammatory diseases including diabetic atherosclerosis (DA). The study aims to explore the role of sinapic acid (SA) in the pyroptosis of macrophages in diabetic atherosclerosis. Our results from the in vivo experiments showed that low-dose (≤ 50 mg/Kg) chronic SA adiministration suppressed serum endothelin 1 (ET-1) and interleukine-1β (IL-1β) contents, pyroptotic death of bone marrow derived macrophages (BMDMs), and the expression of pyroptotic proteins ASC, NRLP3 and Caspase-1...

The tumor suppressor p53 is activated in response to cellular stress to prevent malignant transformation. However, several recent studies have shown that p53 can play protective roles in tumor cell survival under adversity. Whether p53-regulated long noncoding RNAs are involved in this process remains to be fully understood. Here, we show that under glucose starvation condition, p53 directly upregulates a novel lncRNA named TRINGS (Tp53-regulated inhibitor of necrosis under glucose starvation) in human tumor cells...

A substantial fraction of eukaryotic transcripts are considered long non-coding RNAs (lncRNAs), which regulate various hallmarks of cancer. Here, we discovered that the lncRNA HOXB-AS3 encodes a conserved 53-aa peptide. The HOXB-AS3 peptide, not lncRNA, suppresses colon cancer (CRC) growth. Mechanistically, the HOXB-AS3 peptide competitively binds to the ariginine residues in RGG motif of hnRNP A1 and antagonizes the hnRNP A1-mediated regulation of pyruvate kinase M (PKM) splicing by blocking the binding of the ariginine residues in RGG motif of hnRNP A1 to the sequences flanking PKM exon 9, ensuring the formation of lower PKM2 and suppressing glucose metabolism reprogramming...

The roles of long non-coding RNAs in cancer metabolism remain largely unexplored. Here we identify FILNC1 (FoxO-induced long non-coding RNA 1) as an energy stress-induced long non-coding RNA by FoxO transcription factors. FILNC1 deficiency in renal cancer cells alleviates energy stress-induced apoptosis and markedly promotes renal tumor development. We show that FILNC1 deficiency leads to enhanced glucose uptake and lactate production through upregulation of c-Myc. Upon energy stress, FILNC1 interacts with AUF1, a c-Myc mRNA-binding protein, and sequesters AUF1 from binding c-Myc mRNA, leading to downregulation of c-Myc protein...

The Hippo pathway plays essential roles in organ size control and cancer prevention via restricting its downstream effector, Yes-associated protein (YAP). Previous studies have revealed an oncogenic function of YAP in reprogramming glucose metabolism, while the underlying mechanism remains to be fully clarified. Accumulating evidence suggests long noncoding RNAs (lncRNAs) as attractive therapeutic targets, given their roles in modulating various cancer-related signaling pathways. In this study, we report that lncRNA breast cancer anti-estrogen resistance 4 (BCAR4) is required for YAP-dependent glycolysis...
