Long non ‑coding RNA plasmacytoma variant translocation 1 gene promotes the development of cervical cancer via the NF‑κB pathway.

Long non‑coding RNA plasmacytoma variant translocation 1 gene promotes the development of cervical cancer via the NF‑κB pathway. Mol Med Rep. 2019 Jul 09;: Authors: Wang C, Zou H, Yang H, Wang L, Chu H, Jiao J, Wang Y, Chen A Abstract The long noncoding RNA plasmacytoma variant translocation 1 gene (LncRNA PVT1) has an important role in tumor occurrence and development, yet the role and underlying molecular mechanisms of this RNA in cervical cancer have not yet been elucidated. In the present study, three cervical cancer cell lines (HeLa, Ca Ski and SiHa) were used to verify how LncRNA PVT1 mediates cervical cancer development, and the H8 cell line was used as a control. A LncRNA PVT1 overexpression vector or small interfering RNAs targeting LncRNA PVT1 were transfected into cervical cancer cells to generate LncRNA PVT1 overexpression and silencing in these cells. LncRNA PVT1 overexpression accelerated the growth of cervical cancer cells by advancing the cell cycle and inhibiting cellular apoptosis; increases in Cyclin D1 (CCND1) mRNA and activated Bcl‑2 protein expression levels also supported this finding. Furthermore, NF‑κB activation and expression was increased by LncRNA PVT1 overexpression. In addition, NF‑κB activation or inhibition induced changes in cell viability, accompanied by changes in CCND1 and Bcl‑2 expression. Increases or decreases in microRNA‑16 (miR‑16) expression (using miR mimics and inhibitors)...

ConclusionOverall, these guidelines provide consistent recommendations on who should receive breast reconstruction education, who is a candidate for postmastectomy breast reconstruction, and the appropriate timing of reconstruction and extent of mastectomy. Future updates from all should focus on expanding to include alloplastic and autologous forms of reconstruction and should include a broad scope of relevant questions.

This study, therefore, aims to investigate the effects of generalised trust and happiness on all-cause and cause-specific mortality. The distinction between different causes of death (i.e. cardiovascular vs. cancer-related mortality) allowed us to assess if psychosocial mechanisms could account for associations between generalised trust, happiness and mortality. The study sample was derived from US General Social Survey data from 1978 to 2010 (response rates ranged from 70 to 82 per cent), and combined with death records from the National Death Index. The analytical sample comprised 23,933 individuals with 5382 validated d...

Authors: Feng X, Zhang M, Meng J, Wang Y, Liu Y, Liang C, Fan S Abstract We aimed to investigate the potential mechanisms of progression and identify novelprognosis-related biomarkers for papillary renal cell carcinoma (PRCC) patients. The relateddata were derived from The Cancer Genome Atlas (TCGA), and then, analyzed by Weightedgene co-expression network analysis (WGCNA). The correlation between each module andthe clinical traits were analyzed by Pearson's correlation analysis. Pathway analysis wasconducted to reveal potential mechanisms. Hub genes within each module were screenedby intra-module analysis, and vis...

We report a unique case of a 60-year-old woman developing endometrial cancer in a uterine deposit 18 years after she had undergone laparoscopic subtotal hysterectomy with morcellation for benign pathology. She had used unopposed estrogen as menopausal hormone therapy. She presented with a pelvic mass that was causing pressure symptoms. On imaging, the mass had an enhancing vascular nodular component and appeared to abut normal ovaries and the residual cervix. She proceeded to laparotomy, where a 12 cm pelvic mass was found morbidly adherent to the bladder anteriorly and to the cervical stump. The pelvic mass was excise...

Authors: Lee YK, Hwangbo Y, Lee S, Lee DE, Lee EK, Yeom MS, Joo J, Kong SY Abstract Background While aspirin use is known to be associated with reduced incidence of various cancer types, it is unclear if this benefit extends to thyroid cancer. We aimed to evaluate the association between aspirin use and thyroid cancer development. Methods This nested case-control study used nationwide data from the Korean National Health Insurance Service-National Sample Cohort 2002-2015. In total, 4,547 individuals with newly developed thyroid cancer were matched with 13,641 controls based on age, sex, and follow-up period. Odds r...

Conclusion: Following an initial non-diagnostic FNAB, the probability of yielding a diagnostic result declines with each sequential repeat FNAB. Nonetheless, a tangible possibility of malignancy remains even after repeated non-diagnostic FNABs.  . PMID: 31950884 [PubMed - as supplied by publisher]

Even though carcinogenesis might relate to the background disease of the gland, the incidence of DTMc in the setting of various thyroid disorders remains unclear. We designed the present study to address this question. METHODS: We reviewed data from two prospectively collected databases of consecutive patients undergoing thy...

Authors: Gao YL, Zhao ZS, Zhang MY, Han LJ, Dong YJ, Xu B Abstract Emerging evidence suggests that the long non-coding RNA (lncRNA) plasmacytoma variant translocation 1 gene (PVT1) is involved in pathogenesis of cervical cancer. However, the potential mechanism is rarely reported. Our study found that PVT1 was up-regulated in cervical cancer tissue and cell lines. After transfecting PVT1 siRNA, the proliferation, migration and invasion of cervical cancer cells were markedly decreased. MiRNA expression profiles demonstrate that miR-424 was markedly down-regulated in cervical cancer tissue. Bioinformatics analysis re...
