Circular RNA hsa_circ_0103552 Promotes Proliferation, Migration, and Invasion of Breast Cancer Cells through Upregulating Cysteine-Rich Angiogenic Inducer 61 (CYR61) Expression via Sponging MicroRNA-515-5p.

Circular RNAs (circRNAs) exert a significant regulatory function on tumor progression. This work intends to probe into the biological function and regulatory mechanism of circRNA_0103552 (circ_0103552) in breast cancer carcinogenesis. In this study, circ_0103552, microRNA-515-5p (miR-515-5p), and cysteine-rich angiogenic inducer 61 (CYR61) mRNA expressions in breast cancer cells and tissues were determined by quantitative real-time polymerase chain reaction, followed by cell counting kit 8 and Transwell experiments to examine the multiplication, migration, and invasion of breast cancer cells.

Surgery on primary melanoma of the breast.

Malignant melanoma of the breast (MMB) is a rare disease that accounts for 3-5% of all melanomas. It can be expressed as a metastatic mammary gland or primary mammary melanin of the mammary gland. Primary MMB (PMMB) can be divided into two types: parenchymal melanoma without skin involvement and melanoma involving skin on the breast.

Lobaplatin inhibits breast cancer progression, cell proliferation while it induces cell apoptosis by downregulating MTDH expression.

Objective: Lobaplatin shows antitumor activity against a wide range of tumors, including metastatic breast cancer (BCa). The overexpression of metadherin (MTDH) is associated with poor prognosis of BCa patients. This study was designed to investigate the effect of lobaplatin on MCF-7 cell proliferation and its association with MTDH expression.

MicroRNA‑766 inhibits papillary thyroid cancer progression by directly targeting insulin receptor substrate 2 and regulating the PI3K/Akt pathway.

MicroRNAs (miRNAs/miRs) are widely dysregulated in papillary thyroid cancer (PTC). Dysregulated miRNAs, together with their target genes, comprise a complex network that has been implicated in the regulation of PTC pathogenesis. Further knowledge of the functional roles of aberrantly expressed miRNAs in PTC, and the underlying molecular mechanisms, may assist in the identification of novel therapeutic targets.

Steroid receptor coactivator-1 interacts with NF-κB to increase VEGFC levels in human thyroid cancer.

Thyroid cancer is the most common endocrine cancer, and has a high incidence of lymphatic metastasis. Vascular endothelial growth factor C (VEGFC) is essential for development of lymphatic vessels and lymphatic metastases during carcinogenesis. Steroid receptor coactivator-1 (SRC-1) interacts with nuclear receptors and transcription factors to promote tumor proliferation and metastasis.

PI3K inhibitors IC87114 inhibits the migration and invasion of thyroid cancer cell in vitro and in vivo.

Thyroid cancer is currently the most common endocrine malignancies, and PI3K/Akt pathway play an important role during its initiation and development. IC87114 is an inhibitor of PI3K/Akt pathway. Little is known about the role of IC87114 in the initiation and progression of thyroid cancer.

Low expression of long non-coding RNA GAS5 is associated with poor prognosis of patients with thyroid cancer.

The study aims to investigate the role of long non-coding RNA (lncRNA) GAS5 in the diagnosis and prognosis of patients suffering from thyroid cancer (TC). A total of 212 patients with TC and 61 patients with benign thyroid tumor were enrolled in the study. Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to detect the lncRNA GAS5 expression in TC and benign tumor tissues.

Does dual HER-2 blockade treatment increase the risk of severe toxicities of special interests in breast cancer patients: A meta-analysis of randomized controlled trials.

Although dual HER-2 blockade treatment could offer greater clinical efficacy in breast cancer, the risk of severe toxicities of special interest related to this combined regimen in breast cancer remained unknown. We systematically searched public databases (MEDLINE, EMBASE, Cochrane library) to identify relevant studies that comparing anti-HER2 monotherapy (lapatinib or trastuzumab or pertuzumab) with dual HER-2 blockade treatment (pertuzumab plus trastuzumab or trastuzumab plus lapatinib) in breast cancer. A total of 11,941 breast cancer patients from 9 trials were included for analysis.

PTEN/PI3K/AKT protein expression is related to clinicopathological features and prognosis in breast cancer with axillary lymph node metastases.

We explored the relations between PTEN/PI3K/AKT expression and clinicopathological characteristics and prognosis in breast cancer patients with and without axillary lymph node metastasis (LNM). Tissues and follow-up data from 142 patients with (LNM group) and 154 without (non-LNM group) metastases were collected. Expression of PTEN/PI3K/AKT was detected using immunohistochemistry staining.

Comparing the Diagnostic Accuracy of RTE and SWE in Differentiating Malignant Thyroid Nodules from Benign Ones: a Meta-Analysis.

Background: Approximately 10-20 million Americans have been clinically diagnosed with thyroid nodules. Shear wave elastography (SWE) and real-time elastography (RTE) are two primary forms of elastography for identifying the status of thyroid nodules. The aim of this study is to assess the performance of RTE and SWE in identifying malignant thyroid nodules.

MicroRNA-107 is downregulated and having tumor suppressive effect in breast cancer by negatively regulating brain-derived neurotrophic factor.

Background: In the present study, we investigated the possible tumor suppressive effect of microRNA-107 (miR-107) in human breast cancer.

Methods: Gene expression of miR-107 in breast cancer cell lines and clinical breast tissues was evaluated by a quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). MiR-107 was stably overexpressed in MCF-7 and MDA-MB-231 cells via lentiviral transduction.

A network meta-analysis for toxicity of eight chemotherapy regimens in the treatment of metastatic/advanced breast cancer.

Objective: To compare the incidence of toxicity of 8 different chemotherapy regimens, including doxorubicin + paclitaxel, doxorubicin, capecitabine, CMF (cyclophosphamide + methotrexate + 5-fluorouracil), FAC (fluorouracil + doxorubicin + cyclophosphamide), doxorubicin + docetaxel, doxorubicin + cyclophosphamide and paclitaxel in the treatment of metastatic/advanced breast cancer.

Results: This network meta-analysis included 8 randomized controlled trials (RCTs). The findings revealed that, with regard to capecitabine alone regimen exhibited higher incidence of nausea/vomiting than doxorubicin + paclitaxel regimen, doxorubicin alone regimen and paclitaxel alone regimen in the treatment of patients with metastatic/advanced breast cancer (OR = 32.

Long non-coding RNA ANRIL promotes the invasion and metastasis of thyroid cancer cells through TGF-β/Smad signaling pathway.

Objective: To investigate the effect of antisense non-coding RNA in the INK4 locus (ANRIL) on invasion and metastasis of thyroid cancer (TC).
