From Lab to Home: Ultrasensitive Rapid Detection of SARS-CoV-2 with a Cascade CRISPR/Cas13a-Cas12a System Based Lateral Flow Assay.

Currently, CRISPR/Cas-based molecular diagnostic techniques usually rely on the introduction of nucleic acid amplification to improve their sensitivity, which is usually more time-consuming, susceptible to aerosol contamination, and therefore not suitable for at-home molecular testing. In this research, we developed an advanced CRISPR/Cas13a-Cas12a-based lateral flow assay that facilitated the ultrasensitive and rapid detection of SARS-CoV-2 RNA directly from samples, without the need for nucleic acid amplification. This method was called CRISPR LFA enabling at-home RNA testing (CLEAR).

TENT5A Increases Glioma Malignancy and Promotes its Progression.

Background: Recent studies reported that terminal nucleotidyltransferase 5A (TENT5A) is highly expressed in glioblastoma and associated with poor prognosis. In this work, we aim to specify the expression level of TENT5A in different grades of glioma and explore its role in glioma progression.

Methods: GEPIA online tools were used to perform the bioinformatic analysis.

Nimotuzumab plus induction chemotherapy followed by radiotherapy/concurrent chemoradiotherapy plus nimotuzumab for locally advanced nasopharyngeal carcinoma: protocol of a multicentre, open-label, single-arm, prospective phase II trial.

Unlabelled: Epidermal growth factor receptor (EGFR) is a therapeutic target in nasopharyngeal carcinoma (NPC). The optimal combined modality of optimal combined modality of anti--EGFR monoclonal antibodies, induction chemotherapy (ICT), concurrent chemotherapy and radiotherapy for NPC remains poorly defined. None of previous studies have developed subsequent treatment strategies on the basis of stratification according to the efficacy following ICT plus anti-EGFR mAbs.

A Prospective Study on Defining the Indications of Prophylactic Level IB Radiotherapy in Nasopharyngeal Carcinoma Based on a Risk Score Model.

Objective: The aim of the study was to investigate clinical evidence for defining the indications of prophylactic level IB radiotherapy (RT) in nasopharyngeal carcinoma (NPC).

Methods: We conducted a phase 2 prospective study in 116 newly diagnosed patients with NPC treated by intensity-modulated RT. Whether level IB was irradiated is based on the risk score model (RSM).

Overexpression of HOXA10 promotes the growth and metastasis of nasopharyngeal carcinoma.

Deregulation of HOX transcription factor family has frequently been observed in multiple human cancers; however, their role in nasopharyngeal carcinoma remains largely unclear. In the present study, we found that HOX gene family is consistently upregulated in nasopharyngeal carcinoma and identified HOXA10 as one of the mostly upregulated HOX genes. Importantly, we show that HOXA10 overexpression is associated with transcriptional activation of multiple oncogenes essential for nasopharyngeal carcinoma carcinogenesis, including S-phase kinase-associated protein 2 (SKP2), calcium/calmodulin-dependent protein kinase kinase 2 (CAMKK2), and matrix metalloproteinase 1 (MMP1).

The Clinical Outcomes and Toxicities of Induction Chemotherapy Followed by Concurrent Chemoradiotherapy Plus Adjuvant Chemotherapy in Locoregionally Advanced Nasopharyngeal Carcinoma.

Purpose: To analyze the outcomes and toxicities of induction chemotherapy (ICT) followed by concurrent chemoradiotherapy (CCRT) plus adjuvant chemotherapy (ACT) in patients with locoregionally advanced nasopharyngeal carcinoma (LA-NPC).

Methods: Retrospective analysis of 163 patients with LA-NPC referred from August 2015 to December 2018 was carried out. All patients underwent platinum-based ICT followed by CCRT plus ACT.

Autophagic protein Beclin 1 serves as an independent positive prognostic biomarker for non-small cell lung cancer.

Beclin 1, a key regulator of autophagy, has been found to be aberrantly expressed in a variety of human malignancies. Herein, we employed immunohistochemistry (IHC) to detect the protein expression of Beclin 1 in non-small cell lung cancer (NSCLC) and paired normal adjacent lung tissues, and analyzed its clinicopathological/prognostic significance in NSCLC. Receiver operating characteristic (ROC) curve analysis was utilized to determine a cutoff point (>2 VS.
