miR-486 as an unfavorable prognostic biomarker for patients with non-small cell lung cancer.

Background: Non-small cell lung cancer (NSCLC) is the most common malignant tumor in China. miR-486 was found to be associated with many tumors. In previous study, we aimed to investigate the expression and prognostic value of miR-486 in patients with NSCLC.

miR-486-5p functions as an oncogene by targeting PTEN in non-small cell lung cancer.

Purpose: Lung cancer, the leading cause of cancer-related death worldwide, shows a poor 5-year overall survival rate. In our previous study, we demonstrated that miR-486-5p can be a potential blood-based biomarker for early diagnosis and recurrence prediction of non-small cell lung cancer (NSCLC). The aim of the present study was to investigate the possible roles and related target genes of miR-486-5p in NSCLC progression.

Downregulation of HIF-2α Reverse the Chemotherapy Resistance of Lung Adenocarcinoma A549 Cells to Cisplatin.

BACKGROUND Cisplatin (DDP)-based systemic chemotherapy has been widely used in the treatment of postoperative or advanced NSCLC patients, however, its effective rate is only 14~40%. HIF-2α can upregulate drug-resistant-related genes expression and lead to chemotherapy resistance in many tumors. However, little is known about the relationship between HIF-2α and chemotherapy resistance of lung cancer cells.

High expression of SLC6A10P contributes to poor prognosis in lung adenocarcinoma.

Purpose: To investigate the expression profile and prognostic value of SLC6A10P in patients with non-small cell lung cancer (NSCLC).

Patients And Methods: TCGA datasets were used to investigate the differential expression of SLC6A10P in NSCLC, lung adenocarcinoma (LUAD), and lung squamous cell carcinoma (LUSC). Expression of SLC6A10P was measured by in situ hybridization in tissue microarrays containing 136 NSCLC (51 LUAD and 85 LUSC) patients.

HIF-2α not HIF-1α overexpression confers poor prognosis in non-small cell lung cancer.

HIF-α may play an important role in the process of tumorigenesis as well as tumor progression. Although a number of investigations have established the significance of HIF-1α in several human tumors, there is still little information available on the clinical significance of HIF-2α expression in non-small cell lung cancer (NSCLC). In present study, immunohistologic expression of HIF-1α/ HIF-2α was studied in a tissue microarray of 140 Stage I-III NSCLCs and correlated with clinicopathologic parameters and clinical outcome.

Synthesis and biological evaluation of new fluorine substituted derivatives as angiotensin II receptor antagonists with anti-hypertension and anti-tumor effects.

The synthesis and pharmaceutical activity of new potent non-tetrazole angiotensin II (Ang II) receptor antagonists were described. These compounds were fluorine substituted derivatives of Losartan, Valsartan and Irbesartan with carboxylic acid group as replacements to the known potent tetrazole moiety at the 2'-biphenyl position. Their activities were evaluated by Ang II receptor binding assay as well as by in vivo assay.
