Abstract
Long non-coding RNAs (lncRNAs) are a novel class of non-coding RNA (ncRNA), that have been studied extensively in the field of tumor research in recent years. In the case of tumor-associated lncRNAs, lncRNA cytoskeleton regulator RNA (CYTOR) displays extensive functions in tumorigenesis, including invasion, metastasis, malignant proliferation, glycolysis, and inflammatory response. Moreover, the dysregulation of CYTOR is closely related to clinicopathological characteristics, such as tumor stage, lymph node metastasis and infiltration, and poor prognosis of tumor patients. In this review, we provide a novel strategy to summarize the biological functions and clinical value of CYTOR in tumors through an overview of the literature combined with gene set enrichment analysis. A deeper understanding of the role of CYTOR in tumorigenesis may provide new diagnostic, prognostic and therapeutic markers for human tumors.

[PMID: 35494512 PMCID: PMC9050265 DOI: 10.1155/2022/9121554] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 04/02/2022] [Accepted: 04/04/2022] [Indexed: 11/18/2022]
Abstract
Background Increasing evidence shows that dysfunction of noncoding RNAs is implicated in cancer. Neuroblastoma associated transcript 1 (NBAT-1) has been identified as a tumor suppressive lncRNA that is aberrantly expressed in cancers. However, the function and the underlying mechanisms of the NBAT-1 in colorectal carcinoma (CRC) remain unknown. Methods Gene expression was detected by RT-qPCR. The influence of NBAT-1 on CRC was evaluated by the cell counting kit-8 (CCK-8) assay and an in vivo xenograft mouse model. The possible binding of NBAT-1 to miRNAs was predicted via the miRDB online tool and confirmed by a dual-luciferase reporter assay. Protein expression was detected by western blot. Results NBAT-1 expression was significantly decreased in CRC tissues, especially in patients with oxaliplatin (OXA) resistance. NBAT-1 inhibited OXA-resistant CRC cell proliferation in vitro and tumor growth in vivo. The mechanism study revealed that NBAT-1 functioned as a competing endogenous RNA (ceRNA) of miR-4504. NBAT-1 bound miR-4504 and decreased miR-4504 expression in CRC cells. Furthermore, WW-and-C2-domain-containing protein family member 3 (WWC3) was identified as a target of miR-4504. Downregulation of NBAT-1 promoted miR-4504 expression and reduced the level of WWC3. Inhibition of WWC3 by NBAT-1 depletion inactivated Hippo signalling by inhibiting the phosphorylation of large tumor suppressor kinase 1 (LATS1) and yes-associated protein (YAP). Consistently, knockdown of NBAT-1 suppressed the expression of YAP transcriptional targets. Conclusions These findings demonstrated that lncRNA NBAT-1 suppresses OXA-resistant CRC cell growth via inhibition of miR-4504 to regulate the WWC3/LATS1/YAP axis.

Abstract
Background WW and C2 domain-containing protein-3 (WWC3) was identified in our previous studies as a tumor suppressor gene, which inhibits the proliferation and invasiveness of lung cancer cells. However, the relationship between WWC3 and autophagy and apoptosis in lung cancer cells is unclear. In this study, we aimed to investigate the potential role of WWC3 in starvation-induced autophagy and apoptosis in non-small cell lung carcinoma (NSCLC) cells. Methods The immunoblotting assay and quantitative real-time polymerase chain reaction (RT-qPCR) were used for observing the change of WWC3 protein and mRNA level under starvation condition. The immunoblotting assay and immunofluorescence assay were performed to detect the impact of WWC3 expression on autophagy process induced by Earle's balanced salt solution (EBSS) in lung cancer cells; APC/propidium iodide (PI) apoptosis assay, caspase-3/7 activity assay and MTT assay were used for the apoptosis and proliferation detection of lung cancer cells. Results After starvation had been induced with EBSS, WWC3 expression was significantly decreased in the NSCLC cells. Ectopic WWC3 expression weakened the autophagy process in a Beclin1-independent manner and promoted non-small cell lung cancer cell apoptosis via EBSS starvation. Moreover, the inhibition of WWC3 gene knockout was weakened by 3-methyladenine (3-MA), an autophagy inhibitor. Conclusions These results indicate that WWC3 promotes apoptosis and death of starved lung cancer cells, at least partly through autophagy.

Abstract
OBJECTIVE Specific genomic sites can be recognized and permanently modified by genome editing. The discovery of endonucleases has advanced genome editing in pigs, attenuating xenograft rejection and cross-species disease transmission. However, off-target mutagenesis caused by these nucleases is a major barrier to putative clinical applications. Furthermore, off-target mutagenesis by genome editing has not yet been addressed in pigs. METHODS Here, we generated genetically inheritable α-1,3-galactosyltransferase (GGTA1) knockout Yucatan miniature pigs by combining transcription activator-like effector nuclease (TALEN) and nuclear transfer. For precise estimation of genomic mutations induced by TALEN in GGTA1 knockout pigs, we obtained the whole-genome sequence of the donor cells for use as an internal control genome. RESULTS In-depth whole-genome sequencing analysis demonstrated that TALEN-mediated GGTA1 knockout pigs had a comparable mutation rate to homologous recombination-treated pigs and wild-type strain controls. RNA sequencing analysis associated with genomic mutations revealed that TALEN-induced off-target mutations had no discernable effect on RNA transcript abundance. CONCLUSION Therefore, TALEN appears to be a precise and safe tool for generating genome-edited pigs, and the TALEN-mediated GGTA1 knockout Yucatan miniature pigs produced in this study can serve as a safe and effective organ and tissue resource for clinical applications.

Abstract
Significant advances in the treatment of non-small cell lung cancer (NSCLC) have been made over the past decade, and they predominantly involve molecular targets such as epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) rearrangements. However, despite the initial good response, drug resistance eventually develops. The Wnt signaling pathway has recently been considered important in embryonic development and tumorigenesis in many cancers, particularly NSCLC. Moreover, the aberrant Wnt pathway plays a significant role in NSCLC and is associated with cancer cell proliferation, metastasis, invasion and drug resistance, and the suppression of canonical or noncanonical Wnt signaling through various biological or pharmacological negative regulators has been proven to produce specific anticancer effects. Thus, blocking the Wnt pathway via its negative regulators may overcome the resistance of current treatment methods and lead to new treatment strategies for NSCLC. Therefore, in this review, we summarize recent studies on the role of negative regulators in Wnt signaling in NSCLC and the therapeutic potency of these molecules as agents and targets for NSCLC treatments.
