Repression of linc01555 up-regulates angiomotin-p130 via the microRNA-122-5p/clic1 axis to impact vasculogenic mimicry-mediated chemotherapy resistance in small cell lung cancer.

Long non-coding ribonucleic acid 01555 (linc01555) is a brand-new long non-coding RNA (lncRNA) that acts a carcinogenic function in various cancers. However, its role in small cell lung cancer (SCLC) is uncertain. This research was to figure out the role of linc01555 in cisplatin (DDP) resistance of SCLC cells and its possible latent mechanism.

RP11‑284F21.9 promotes lung carcinoma proliferation and invasion via the regulation of miR‑627‑3p/CCAR1.

Lung carcinoma is a prominent cause of mortality among patients with cancer. Previous studies have reported the vital role of long non‑coding RNAs (lncRNAs) in the malignant progression of lung cancer. lncRNA RP11‑284F21.

Metformin inhibits metastatic breast cancer progression and improves chemosensitivity by inducing vessel normalization via PDGF-B downregulation.

Background: Vascular maturity and functionality are closely associated with tumor progression and chemosensitivity. The antidiabetic agent metformin has shown its ability to inhibit tumor angiogenesis in metastatic breast cancer models. However, it remains unclear if or how metformin remodels the abnormal vasculature of metastatic breast cancer, while inhibiting angiogenesis.

AmotP130 regulates Rho GTPase and decreases breast cancer cell mobility.

Angiomotin (Amot) is a newly discovered, multifunctional protein that is involved in cell migration and angiogenesis. However, the role of its isoform, AmotP130, in the regulation of cytoskeleton and metastasis of breast cancer, is unclear. The aim of this study was to investigate the role of AmotP130 in the reorganization of the actin cytoskeleton and the changes of morphology in breast cancer cells through the Rho pathway that influences the invasion and migration of cells.

Characteristics of Differently Located Colorectal Cancers Support Proximal and Distal Classification: A Population-Based Study of 57,847 Patients.

Background: It has been suggested that colorectal cancer be regarded as several subgroups defined according to tumor location rather than as a single entity. The current study aimed to identify the most useful method for grouping colorectal cancer by tumor location according to both baseline and survival characteristics.

Methods: Cases of pathologically confirmed colorectal adenocarcinoma diagnosed from 2000 to 2012 were identified from the Surveillance, Epidemiology, and End Results database and categorized into three groups: right colon cancer (RCC), left colon cancer (LCC), and rectal cancer (ReC).

The efficiency and safety of trastuzumab and lapatinib added to neoadjuvant chemotherapy in Her2-positive breast cancer patients: a randomized meta-analysis.

Background: The addition of human epidermal growth factor receptor 2 (Her2) therapies to neoadjuvant chemotherapy (NAC) during treatment of Her2-positive breast cancer has been proposed as an effective way to improve the prognosis. However, the treatment outcomes of adding trastuzumab, lapatinib, or both to NAC were not unequivocal in randomized clinical trials. Based on these data, a meta-analysis was performed.

Efficacy and safety of icotinib as first-line therapy in patients with advanced non-small-cell lung cancer.

Background And Objective: Several clinical trials have proven that icotinib hydrochloride, a novel epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor, exhibits encouraging efficacy and tolerability in patients with advanced non-small-cell lung cancer (NSCLC) who failed previous chemotherapy. This study was performed to assess the efficacy and toxicity of icotinib as first-line therapy for patients with advanced pulmonary adenocarcinoma with EGFR-sensitive mutation.

Patients And Methods: Thirty-five patients with advanced NSCLC with EGFR-sensitive mutation who were sequentially admitted to the First Affiliated Hospital of Xi'an Jiaotong University from March 2012 to March 2014 were enrolled into our retrospective research.

Utility of gonadotropin-releasing hormone agonists for prevention of chemotherapy-induced ovarian damage in premenopausal women with breast cancer: a systematic review and meta-analysis.

Background: Premature ovarian failure and infertility following chemotherapy are major concerns for premenopausal women with breast cancer. A potential ovarian function preservation strategy is administration of gonadotropin-releasing hormone (GnRH) agonists during adjuvant chemotherapy; however, studies of the clinical efficacy of GnRH agonists to protect chemotherapy-induced ovarian damage have shown mixed results.

Objective: This meta-analysis study was designed to estimate the efficacy of GnRH agonists administered concurrently with chemotherapy to prevent chemotherapy-induced ovarian damage in premenopausal women with breast cancer.

Ipsilateral breast metastasis from a pulmonary adenocarcinoma: a case report and a focused review of the literature.

Metastases to the breast from extramammary malignancies are extremely rare. Ruling out the diagnosis of primary breast tumor is important in order to decide on clinical management and predict prognosis. We report a case of metastasis to the breast from a pulmonary adenocarcinoma, with extensive micropapillary component, diagnosed concomitantly with the primary tumor.

[The relationship of virus load, receptor expression and tumor spectrum in layer chickens infected by ALV-J].

Abstract:Subgroup J avian leukosis virus (ALV-J) infect cells by binding to the chNHE1 receptor protein of the host and causes tumors. The tumor incidence of the ALV-J-infected chickens was observed by histo pathology, and virus was isolated on DF-1 cell line. The ALV-J load and mRNA of chNHElreceptor protein were detected by real time PCR.

RNA-binding domain of the key structural protein P7 for the Rice dwarf virus particle assembly.

The Rice dwarf virus (RDV) P7 structural protein is the key protein in the RDV particle assembly. The P7 protein was digested partially or completely by Staphylococcus aureus V8 protease and/or Pseudomonas fragi Asp-N protease. The molecular mass and the N-terminal amino acid sequence of the polypeptide fragments of the P7 protein were determined by SDS-PAGE and the Edman degradation method, respectively.

Accumulation of pathogenesis-related type-5 like proteins in phytoplasma-infected garland chrysanthemum Chrysanthemum coronarium.

Soluble proteins extracted from leaves, apical shoots, axillary shoots, and stems of garland chrysanthemum plants infected by onion yellows phytoplasma were analyzed by two-dimensional gel electrophoresis. Computerized matching analysis revealed that at least six soluble proteins were accumulated specifically in phytoplasma-infected garland chrysanthemum. N-terminal amino acids sequences of these soluble proteins, determined by Edman degradation, shared high sequence similarities with those of pathogenesis-related type-5 (PR-5) proteins such as tobacco thaumatin-like protein.
