The incidence of thyroid cancer is rising globally. Most patients progress slowly, but some patients develop lymph node and distant metastasis earlier, and their prognosis is poor. Therefore, early diagnosis and warning of malignancy are very meaningful for such patients. SAS1B gene is a newly discovered protein expressed on the surface of mature egg cells and has metalloendopeptidase activity. We aimed at exploring whether SAS1B is involved in the occurrence of thyroid cancer, and at providing evidence for early diagnosis and targeted therapy of thyroid cancer.

In this study, a rabbit anti-human SAS1B polyclonal antibody was prepared by gene recombination technology. The indirect ELISA method was used to detect the SAS1B protein expression in the serum of 69 patients with thyroid cancer and 55 normal controls, and the relevant pathological factors were analyzed. Immunohistochemistry and PCR technology were used to investigate the expression levels of SAS1B protein and mRNA in 30 thyroid cancer tissues anncy.
The above data indicate that the SAS1B gene is closely related to the process of thyroid cancer and can serve as a good tumor marker that can be used for early diagnosis and early warning of thyroid malignancy.Long noncoding RNAs (lncRNAs) are important participants in biological processes including cell proliferation, differentiation and death, as well as pathogenesis of various diseases. LncRNA differentiation antagonizing non-protein coding RNA (DANCR) is an emerging regulator in cell metabolism and many diseases besides cancers. DANCR is negative in epidermal, osteoblastic and endoderm differentiation, but positive in chondrogenic differentiation of progenitor cells. It is protective for calcification of the ligamentum flavum, stroke, acute myocardial infarction and arterial calcification, but a risk factor for bone loss, fracture healing and idiopathic pulmonary fibrosis. In addition, DANCR is a potential target for improving tissue regeneration. Mechanically, DANCR, a cytoplasmic lncRNA, sponges corresponding microRNAs or interacts with various proteins. This review aims to summarize the role of DANCR in progenitor cells and provide perspectives for further studies.
The aim of the study was to summarize and update evidence on whether intra-operative ultrasonography (IOUS) guided breast conserving surgery (BCS) can be more effective than wire-guided or palpation-guided excision for both nonpalpable, as well as palpable breast cancers in achieving tumor free negative margins after lumpectomy for breast cancer.

Comprehensive searches were done systematically through PubMed, Scopus, CENTRAL (Cochrane Central Register of Controlled Trials) and Google scholar databases. Statistical analysis was done using STATA version 13.0. The primary outcome was proportion of patients that achieved tumor free resection margins after lumpectomy. Effect sizes were reported as pooled relative risks (RR). All estimates were reported with 95% confidence intervals (CI).

A total of 20 RCTs with 2519 participants were included in the meta-analysis. Use of intra-operative ultrasonography was associated with 1.18 times higher chances [RR 1.18; 95% CI, 1.10-1.27] of attaining a tumor free margin for all breast cancers, 1.16 times higher chances [RR 1.16; 95% CI, 1.10-1.23] of attaining a tumor free margin for all palpable breast cancers and 1.20 times higher chances [RR 1.20; 95% CI, 1.05-1.38] of attaining a tumor free margin for all non-palpable breast, compared to wire guided or palpation guided localization. There was no evidence of publication bias.

The findings support that intra-operative ultrasonography increases the chances of obtaining negative margins for tissue resected in breast conserving surgeries. The findings support the observations of previous reviews published in this aspect nearly half a decade back.

To explore the role of long intergenic non-coding ribonucleic acid 483 (LINC00483) in the development of breast cancer (BC) and its possible mechanism of action.

LINC00483 expression level in BC tissues and cell lines was detected via quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR). The association between LINC00483 expression and survival rate of BC patients was analyzed using Kaplan-Meier survival analysis. The binding relation between LINC00483 and insulin-like growth factor 2 mRNA-binding protein 1 (IGF2BP1) was verified via RNA immunoprecipitation (RIP) and RNA pull-down assays. The expression of IGF2BP1 in BC patients was determined using qRT-PCR. Moreover, the role of LINC00483 on the proliferative ability of BC cells was detected via cell counting kit-8 (CCK8) and 5-Ethynyl-2'-deoxyuridine (EdU) assays. Whether LINC00483 exerts its effects under the regulation of IGF2BP1 was verified via reversal assay.

The results of qRT-PCR showed that LINC00483 had a significantly high ffect of promoting proliferation of BC cells may be regulated by IGF2BP1.
LncRNA urothelial cancer associated 1 (UCA1) is involved in the development of laryngeal squamous cell carcinoma (LSCC), however, its specific mechanism is not fully clear.

Quantitative reverse transcription-PCR (RT-qPCR) was conducted to determine the expressions of lncRNA-UCA1, miR-185-5p and homeobox A13 (HOXA13) in LSCC tissues and cell lines. Cell Counting Kit-8 assay, colony formation assay, wound healing assay, Transwell and flow cytometry, DIANA-LncBase V2, as well as Starbase, Targetscan, and Dual-Luciferase reporter gene system were conducted to detect and confirm the crosstalk networks among lncRNA-UCA1, miR-185-5p, and HOXA13.

The levels of UCA1 and HOXA13 were significantly higher and the expression of miR-185-5p was reduced in LSCC tissues and cell lines. this website Moreover, miR-185-5p was predicted as a target gene for lncRNA UCA1, while HOXA13 was the target gene for miR-185-5p. UCA1 siRNA inhibited the proliferation and invasion of LSCC cells, moreover, the proliferation and invasion of LSCC cells were suppressed by miR-185-5p mimics but were enhanced by miR-185-5p inhibitor.this website
