Fluorescence-plane polarization for the real-time monitoring of transferase migration in living cells.

Transferases are enzymes that exhibit multisite migration characteristics. Significantly, enzyme activity undergoes changes during this migration process, which inevitably impacts the physiological function of living organisms and can even lead to related malignant diseases. However, research in this field has been severely hindered by the lack of tools for the simultaneous and differential monitoring of site-specific transferase activity.

Correction: Ultrasensitive recognition of AP sites in DNA at the single-cell level: one molecular rotor sequentially self-regulated to form multiple different stable conformations.

Immunotherapeutic strategies for sarcoma: current perspectives.

There are more than 100 sarcoma subtypes, each of which is uncommon and challenging to diagnose. Most patients with locally advanced and unresectable sarcomas are still treated with cytotoxic chemotherapy and have low long-term survival. Therefore, novel therapeutic methods are needed to improve the prognosis of patients with sarcomas.

The regulatory roles of long noncoding RNAs in osteoporosis.

Osteoporosis is a common metabolic bone disease characterized by low bone mineral density (BMD) and microarchitectural deterioration of bone tissue, which leads to decreased bone strength and increased fracture risk. Osteoporosis mainly results from a disruption of the balance between bone formation mediated by osteoblasts and bone resorption mediated by osteoclasts. At present, the molecular mechanisms underlying osteoporosis are still not fully understood.

Cysteine-rich intestinal protein 1 silencing alleviates the migration and invasive capability enhancement induced by excessive zinc supplementation in colorectal cancer cells.

Cysteine-rich intestinal protein 1 (CRIP1) is overexpressed in colorectal cancer (CRC) tissues and functions as an oncogene in regulating the migration and invasion of CRC cells. However, the underlying mechanism is unclear. CRIP1 has a role in zinc absorption and functions as an intracellular zinc transport protein.

MiR-211 inhibits cell proliferation and invasion of gastric cancer by down-regulating SOX4.

Introduction: Previous studies have shown that the dysregulation of miRNAs are frequently associated with cancer progression. Deregulation of miR-211 has been observed in various types of human cancers. However, its biological function in gastric cancer (GC) is still unknown.

Effects of PPARγ agonistrosiglitazone on human retinoblastoma cell in vitro and in vivo.

The aim of the study was to evaluate the antitumor effects of the PPARγ agonist rosiglitazone on the human retinoblastoma. The cell biological behavior was detected, specifically, the effects of rosiglitazone on cell viability and apoptosis of the human retinoblastoma Y79 cells were investigated by MTT assay and Hochest 33258 staining and the migration assay showed that rosiglitazone blocked the invasion and migration of the carcinoma cells through the reconstituted extracellular matrix (Matrigel). The effect of rosiglitazone on NF-κB-dependent reporter gene transcription induced by LPS was analyzed by NF-κB-luciferase assay.

Expression of long non-coding RNA ZEB1-AS1 in esophageal squamous cell carcinoma and its correlation with tumor progression and patient survival.

Background: LncRNA ZEB1-AS1 has been identified as a tumor oncogene in hepatocellular carcinoma. However, the clinical significance in esophageal squamous cell carcinoma (ESCC) is still unknown. The aim of this study was to explore ZEB1-AS1 expression levels and evaluated its clinical significance in ESCC patients.

Protection effect of survivin protein overexpression on acute myocardial infarction in rats.

To investigate the protective effect of adenovirus mediated Survivin protein overexpression on acute myocardial infarction in rats. 45 acute myocardial infarction rat models were constructed by suture method and were randomly divided into sham group, model group and treatment group. The treatment group was injected with Survivin gene packed virus via ventricle.

miRNA-221 promotes proliferation, migration and invasion by targeting TIMP2 in renal cell carcinoma.

Introduction: MicroRNAs (miRNAs) play important roles in tumorigenesis. In this study, we investigated the role of miR-221 in the development and progression of clear cell renal cell carcinoma (ccRCC).

Methods: Quantitative real-time PCR (qRT-PCR) was used to measure the expression level of miR-221 in ccRCC tissues and cell lines.

Expression of miR-32 in human non-small cell lung cancer and its correlation with tumor progression and patient survival.

Introduction: miR-32 has recently been found to be implicated in many critical processes in various types of human cancer. However, its clinical significance in human non-small cell lung cancer (NSCLC) has not yet been elucidated. In the present study, we investigated the expression of miR-32 in NSCLC and analyzed its association with clinical features and prognosis of NSCLC patients.
