The aim of this randomised non-inferiority clinical trial was to compare the effectiveness of semi-annual (every six months) applications of 25 % silver nitrate (AgNO

) solution followed by 5 % sodium fluoride (NaF) varnish to semi-annual applications of 38 % silver diamine fluoride (SDF) solution in arresting early childhood caries (ECC).

Three-year-old children with active cavitated carious lesions were recruited and randomly assigned to two intervention groups. Children in Group A received semi-annual applications of 25 % AgNO

solution followed by 5 % NaF varnish on carious lesions. Children in Group B received semi-annual applications of 38 % SDF solution followed by a placebo varnish. One trained dentist assessed ECC status at baseline and in all follow-up examinations. An independent operator performed the interventions. The dentist, the children, and their caretakers were blinded to the intervention allocation. Data were analysed using a non-inferiority test. Group A's non-inferiority would be as.

Long non-coding RNAs (lncRNAs) are associated with cancer development, while their relationship with the cancer-associated stromal components remains poorly understood. Raptinal In this review, we performed a broad description of the functional landscape of stroma-associated lncRNAs in various cancers and their roles in regulating the tumor-stroma crosstalk.

We carried out a systematic literature review of PubMed, Scopus, Medline, Bentham, and EMBASE (Elsevier) databases by using the keywords "LncRNAs in cancer," "LncRNAs in tumor stroma," "stroma," "cancer-associated stroma," "stroma in the tumor microenvironment," "tumor-stroma crosstalk," "drug resistance of stroma," and "stroma in immunosuppression" till July 2020. We collected the latest articles addressing the biological functions of stroma-associated lncRNAs in cancer.

These articles reported that dysregulated stroma-associated lncRNAs play significant roles in modulating the tumor microenvironment (TME) by the regulation of tumor-stroma crosstalk, epithelial to mesenchymal transition (EMT), endothelial to mesenchymal transition (EndMT), extracellular matrix (ECM) turnover, and tumor immunity.

The tumor stroma is a substantial portion of the TME, and the dysregulation of tumor stroma-associated lncRNAs significantly contributes to cancer initiation, progression, angiogenesis, immune evasion, metastasis, and drug resistance. Thus, stroma-associated lncRNAs could be potentially useful targets for cancer therapy.

Recurrent copy number alterations of specific chromosomal loci may result in gains of oncogenes or losses of tumor suppressor genes and become entrenched in the genomic framework of certain types of cancers. The locus at chromosome 8p11.23 presents recurrent amplifications most commonly in squamous lung carcinomas, breast cancers, squamous esophageal carcinomas, and urothelial carcinomas. Amplification is rare in other cancers. The amplified segment involves several described oncogenes that may promote cancer cell survival and proliferation, as well as less well characterized genes that could also contribute to neoplastic processes. Genes proposed to be "drivers" in 8p11.23 amplifications include ZNF703, FGFR1 and PLPP5. Additional genes in the locus that could be functionally important in neoplastic networks include co-chaperone BAG4, lysine methyltransferase NSD3, ASH2L, a member of another methyltransferase complex, MLL and the mRNA processing and translation regulators LSM1 and EIF4EBP1. In this paper, genes located in the amplified segment of 8p11.23 will be examined for their role in cancer and data arguing for their importance for cancers with the amplification will be presented.

To investigate the functional role of circSFMBT2 in vascular smooth muscle cell (VSMC) proliferation and migration and the underlying molecular mechanism.

The circSFMBT2 levels in neointimal tissue and platelet derived growth factor-BB (PDGF-BB)-treated VSMCs were detected by qRT-PCR. The role of circSFMBT2 in VSMC proliferation, migration and cell cycle distribution was assessed by MTT assay, transwell assay, wound healing assay and flow cytometry. The protein expression of contractile markers was evaluated by western blot. In vitro luciferase reporter assay, RNA pull-down assay, ChIP and coimmunoprecipitation (CoIP) were performed to explore the effects of circSFMBT2 on the downstream signaling pathway.

We found that circSFMBT2 was markedly increased in neointimal tissue relative to normal tissue and PDGF-BB-treated VSMCs relative to control VSMCs. The knockdown of circSFMBT2 by siRNA significantly inhibited the proliferation and migration of VSMCs. Interestingly, circSFMBT2 knockdown enhanced the expression of contractile marker proteins including SM22α, SM myosin heavy chain (SMMHC) and calponin. Further data demonstrated that circSFMBT2 interacted with miR-331-3p as a competing endogenous RNA and up-regulated the expression of histone deacetylase 5 (HDAC5), thereby regulating the level of angiogenic factor with G patch and FHA domains (Aggf1).

These results revealed that circSFMBT2 plays a vital role in VSMC proliferation and migration through the miR-331/HDAC5/Aggf1 axis, and suggest a novel target for treating proliferative vascular diseases.

RNA regulatory genes were closely associated with tumorigenesis and prognosis in multiple tumors. Copy number variation (CNV) is a frequent characteristic in soft tissue sarcomas (STS). However, little is known regarding their possible roles in STS.

RNA sequence profiles and CNV data of 255 STS patients were downloaded from the Cancer Genome Atlas (TCGA). The correlation analysis involved CNVs of RNA regulatory genes, patient survival, immune infiltration, and DNA methylation. Drug sensitivity (IC50) was analyzed and validated by MTT assays in STS cell lines.

CNV events were frequently observed in all kinds (m6A, m5C, ac4C, m1A, m3C, m6Am, m7G, and Ψ) of RNA regulatory genes. Diploid copy number (CN) of METTL4 was associated with better overall survival (OS) in STS and the subtypes (leiomyosarcoma, LMS; dedifferentiated liposarcoma, DDLPS). In STS and LMS, diploid CN of METTL4 was significantly associated with higher infiltration fraction of resting mast cells. In STS and DDLPS, diploid CN of METTL4 possessed lower methylation level in CpG site of cg12105018, which represented better OS.
