KLF14/miR-1283/TFAP2C axis inhibits HER2-positive breast cancer progression via declining tumor cell proliferation.

MiR-1283 has been identified as a tumor suppressor in some malignancies. Whereas, the role of miR-1283 in HER2-positive (HER2+) breast cancer, particularly its role in regulating cell proliferation, one of the most significant features of tumor progression, is unclear. The related microRNA screened by the breast cancer sample GSE131599 dataset were detected in HER2+ breast cancer tissues and cell lines.

Circular RNA circ-ERBB2 promotes HER2-positive breast cancer progression and metastasis via sponging miR-136-5p and miR-198.

Background: Circular RNAs (circRNAs) are pivotal regulators of various human cancers and circ-ERBB2 is abnormally expressed in breast cancer cells. However, the role and mechanism of circ-ERBB2 in HER2-positive breast cancer are still unknown.

Methods: The circ-ERBB2 expressions in the tumor tissues of HER2-positive breast cancer patients were tested using quantitative real-time PCR.

Hsa_circ_0023990 Promotes Tumor Growth and Glycolysis in Dedifferentiated TC via Targeting miR-485-5p/FOXM1 Axis.

Background: During the transformation to dedifferentiated thyroid cancer (TC) types, the ability of papillary thyroid carcinomas (PTCs) to concentrate radioactive iodine might be lost, raising difficulty for the current therapy. circRNAs were proved to be implicated in the progression of various cancers. In this study, we aimed to investigate the functional role and mechanism of hsa_circ_0023990 in dedifferentiated TC.

Lnc RNA SNHG20 participated in proliferation, invasion, and migration of breast cancer cells via miR-495.

To explore the mechanism of lnc SNHG20 in the regulation of proliferation, invasion, and migration of breast cancer cells. mRNA levels of SNHG20, miR-495, and HER2 were detected by qRT-PCR. Protein level of HER2 was measured by Western blot.

Preparation and Identification of HER2 Radioactive Ligands and Imaging Study of Breast Cancer-Bearing Nude Mice.

Objective: A micro-molecule peptide TP1623 of Tc-human epithelial growth factor receptor 2 (HER2) was prepared and the feasibility of using it as a HER2-positive molecular imaging agent for breast cancer was evaluated.

Methods: TP1623 was chemically synthesized and labeled with Tc. The labeling ratio and stability were detected.

Mutations of C-reactive protein (CRP) -286 SNP, APC and p53 in colorectal cancer: implication for a CRP-Wnt crosstalk.

C-reactive protein (CRP) is an established marker of inflammation with pattern-recognition receptor-like activities. Despite the close association of the serum level of CRP with the risk and prognosis of several types of cancer, it remains elusive whether CRP contributes directly to tumorigenesis or just represents a bystander marker. We have recently identified recurrent mutations at the SNP position -286 (rs3091244) in the promoter of CRP gene in several tumor types, instead suggesting that locally produced CRP is a potential driver of tumorigenesis.

[Differentiation of rat bone marrow mesenchymal stem cells into adipocytes and blockage of the differentiation].

Objective: To explore the pathogenesis of tumors by blocking the normal differentiation process of stem cells.

Methods: Bone marrow mesenchymal stem cells (BMSCs) from rats were isolated, cultured and purified by whole bone marrow adherence method. The rat BMSCs were induced to differentiate into adipocytes with dexamethasone, insulin and indomethacin.

Early recurrence and death after esophagectomy in patients with esophageal squamous cell carcinoma.

Background: The aim of this retrospective study is to analyze recurrence and death within 1 year after esophagectomy in patients with esophageal carcinoma.

Methods: The records of 533 consecutive patients with esophageal squamous cell carcinoma who underwent surgery from January 2002 to January 2005 were reviewed. Patients who died of recurrence within 1 year after operation (group A) were compared with patients who survived more than 5 years without any recurrence (group B).

[Clinical observation on effect of fuzheng yiliu granule on cell cycle and nuclear transcription factor-kappa B in tissue of esophageal-gastric carcinoma].

Objective: To observe the effect of Fuzheng Yiliu Granule (FZYLG) on cell cycle and nuclear transcription factor-kappa B (NF-kappa B) in tissue of esophageal-gastric carcinoma.

Methods: Seventy-six patients with esophageal gastric carcinoma were randomly divided into two groups, the FZYLG group and the control group. FZYLG was given to the former for 15 days.
