Online ahead of print. ABSTRACT BACKGROUND: A rich history of studies have manifested the importance of miRNAs to cancer progression, while miR-194-3p has been seldom explored. OBJECTIVE: The purpose of this study is to unearth the way the KLK10/miR-194-3p axis modulates colorectal cancer (CRC). METHODS: Differentially expressed genes of CRC in TCGA database were analyzed. Western blot and qRT-PCR were employed to test protein and mRNA expressions of two researched genes. Their targeting was confirmed using dual-luciferase. Biological behaviors of cells were tested by a series of cellular functional assays. RESULT: Remarkably low miR-194-3p expression and high KLK10 expression were observed in cancer cells. Overexpressing miR-194-3p hindered the progression of CRC cells. Overexpression of miR-194-3p significantly weakened the promoting effect of upregulat ed KLK10 on cell migration, invasion and proliferation. Their targeting was verified by dual -luciferase assay. Therefore, miR-194-3p hindered cell behaviors of CRC through KLK10. CONCLUSION: This investigation casts new light on the treatment of CRC through the KLK10/miR-194-3p axis.

The Nonrecurrent Laryngeal Nerve Without Abnormal Subclavian Artery: Report of Two Cases and Review of the Literature

xlomafota13 shared this article with you from Inoreader The Nonrecurrent Laryngeal Nerve Without Abnormal Subclavian Artery: Report of Two Cases and Review of the Literature Via ear nose throat Ear Nose Throat J. 2021 Dec 22:1455613211056547. doi: 10.1177/01455613211056547. Online ahead of print. ABSTRACT As a variant of recurrent inferior laryngeal nerve (RILN), the nonrecurrent inferior laryngeal nerve (NRILN) is closely related to the occurrence of abnormal subclavian artery (ASA). The nonrecurrent inferior laryngeal nerve has been found in patients without arterial abnormalities, which is seen in the coexistence of NRILN and RILN, but it is easily confused with sympathetic-inferior laryngeal anastomosis branch (SILAB). We encountered 2 right NRILN patients without ASA during thyroid surgery. This article summarizes the characteristics of these cases and proposes methods to distinguish the coexistence of NRILN and RILN from SILAB. So far, 11 articles have reported 16 cases of NRILN without arterial abnormalities. In patients without artery abnormality, the vagus nerve could send out a descending branch NRILN at the bifurcation of the carotid artery and enter the larynx after anastomosis with RILN. Adequate dissection of the carotid sheath may avoid confusion with SILAB, and neural monitoring is also expected to provide a reference for the identification.

Paracrine mechanisms of endothelial progenitor cells in vascular repair

xlomafota13 shared this article with you from Inoreader Paracrine mechanisms of endothelial progenitor cells in vascular repair Via histochem Acta Histochem. 2021 Dec 17;124(1):151833. doi: 10.1016/j.acthis.2021.151833. Online ahead of print. ABSTRACT Endothelial progenitor cells (EPCs) play an important role in repairing damaged blood vessels and promoting neovascularization. However, the specific mechanism of EPCs promoting vascular repair is still unclear. Currently, there are two different views on the repair of damaged vessels by EPCs, one is that EPCs can directly differentiate into endothelial cells (ECs) a nd integrate into injured vessels, the other is that EPCs act on cells and blood vessels by releasing paracrine substances. But more evidence now supports the latter. Therefore, the paracrine mechanisms of EPCs are worth further study. This review describes the substances secreted by EPCs, some applications based on paracrine effects of EPCs, and the studies of paracrine mechanisms in cardiovascular diseases--all of these are to support the view that EPCs repair blood vessels through paracrine effects rather than integrating directly into damaged vessels.

Comparison of efficacy and toxicity of chemoradiation regimens for head and neck squamous cell carcinoma primary treatment

xlomafota13 shared this article with you from Inoreader Comparison of efficacy and toxicity of chemoradiation regimens for head and neck squamous cell carcinoma primary treatment Via Head & Neck Abstract Background The best chemoradiation regimen to treat locally and regionally advanced head and neck squamous cell carcinoma (HNSCC) is yet to be established. Methods We compared overall survival (OS) and adverse events following chemoradiation regimens (high-dose [HDC] or low-dose [LDC] cisplatin, or carboplatin [CB]) in HNSCC cases selected from SEER-Medicare linked database. Results Of the 1335 cases who underwent radiotherapy, 264 received HDC, 259 received LDC, and 353 received CB, concurrently. Compared to chemoradiation with HDC, using LDC or CB, or radiotherapy alone were associated with an increasingly worse OS; hazard ratios were 1.33, p = 0.03; 1.35, p = 0.02; and 2.12, p < 0.001; respectively. There were no differences in the rates of adverse events between the three chemoradiation regimens. Conclusion Chemoradiation regimen using HDC appears to be the best primary treatment for locally and regionally advanced HNSCC. Nonetheless, prospective large studies are warranted to further determine its absolute benefit. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Efficacy and Safety of External Volume Expansion (EVE) on Fat Grafting: A Systematic Review and Single-Arm Meta-Analysis

xlomafota13 shared this article with you from Inoreader Efficacy and Safety of External Volume Expansion (EVE) on Fat Grafting: A Systematic Review and Single-Arm Meta-Analysis Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2021 Nov 16:S1748-6815(21)00576-3. doi: 10.1016/j.bjps.2021.11.032. Online ahead of print. ABSTRACT BACKGROUND: The autologous fat grafting is commonly used for reconstructive or aesthetic purposes. However, due to the huge variation in methods, its retention rate varies a lot. External volume expansion (EVE) has been used to treat recipient sites of fat grafting. Concerns have been raised regarding its efficacy and safety. METHODS: We have searched PubMed, EMBASE, and the Cochrane Library for studies on EVE-assisted fat grafting published from 2000 to 2020. A meta-analysis was conducted to pool the retention rate. The incidence of complications was assessed for reconstructive or aesthetic purposes. RESULTS: The 11 included studies involved 1152 patients with operations on 1794 breasts. Four studies were included in the meta-analysis. The pooled retention rate was 65% [95%CI 49, 79]. Eight stu dies reported the complications. The total complication incidence was 34%, which is 35% for the aesthetic group and 33% for the reconstructive group. The complication rate was not obviously different between the two groups. CONCLUSIONS: The study shows that the EVE-assisted fat grafting has better retention rate than traditional fat grafting. However, the data showed that the complication rate was much higher in the EVE-assisted group. PMID:34930704 | DOI:10.1016/j.bjps.2021.11.032 View on the web Inoreader.

Knockdown of circular RNA hsa_circ_0062270 suppresses the progression of melanoma via downregulation of CDC45

xlomafota13 shared this article with you from Inoreader Knockdown of circular RNA hsa_circ_0062270 suppresses the progression of melanoma via downregulation of CDC45 Via Cellular and Molecular Biology Histol Histopathol. 2021 Dec 21:18412. doi: 10.14670/HH-18-412. Online ahead of print. ABSTRACT BACKGROUND: Although systemic therapies for melanoma have been improved, the 5-year survival rate of this aggressive cancer remains poor. It has been shown that hsa_circ_0062270 was upregulated in patients with melanoma. However, the relevant mechanism of hsa_circ_0062270 in the progression of melanoma remains unclear. METHODS: The CCK-8, EdU staining, flow cytometry, and transwell assays were used to determine the viability, proliferation, apoptosis and invasion in melanoma cells. An in vivo animal study was performed finally. RESULTS: The level of hsa_circ_0062270 was significantly upregulated in melanoma cells. In addition, hsa_circ_0062270 knockdown markedly inhibited the viability, proliferation, invasion and promoted the apoptosis of melanoma cells. Cell division cycle protein 45 (CDC45) is the host gene of hsa_circ_0062270 , and downregulation of hsa_circ_0062270 notably decreased the expression of CDC45 in melanoma cells. Rescue assays confirmed that hsa_circ_0062270 regulated the growth of melanoma cells through CDC45. Moreover, RIP analysis showed that hsa_circ_0062270 interacted with RNA-binding protein (RBP) EIF4A3. Furthermore, in vivo study indicated that knockdown of hsa_circ_0062270 inhibited the melanoma tumor growth in vivo. CONCLUSIONS: Downregulation of hsa_circ_0062270 can inhibit the progression of melanoma through downregulation of CDC45. Our findings provide biological mechanisms for the use of hsa_circ_0062270 as a biomarker for melanoma and potential therapeutic target.
