Dihydroartemisinin enhances the radiosensitivity of breast cancer by targeting ferroptosis signaling pathway through hsa_circ_0001610.

Objective: This study aimed to elucidate how DHA enhances the radiosensitivity of BC and to explain its potential mechanisms of action.

Methods: The circular structure of hsa_circ_0001610 was confirmed by Sanger sequencing, RNase R treatment, RT-PCR analysis using gDNA or cDNA. Cellular localization of hsa_circ_0001610 and microRNA-139-5p (miR-139-5p) was detected by fluorescence in situ hybridization.

Rapid Selection of Patients Suitable for Deep Inspiration Breath-Hold Using an Automatic Delineating System and RapidPlan Model in Patients With Left Breast Cancer Undergoing Adjuvant Radiation Therapy With IMRT.

Purpose: This study aimed to determine whether radiation therapy plans created using an automatic delineating system and a RapidPlan (RP) module could rapidly and accurately predict heart doses and benefit from deep inspiratory breath-hold (DIBH) in patients with left breast cancer.

Methods And Materials: One hundred thirty-six clinically approved free breathing (FB) plans for patients with left breast cancer were included, defined as manual delineation-manual plan (MD-MP). A total of 104 of 136 plans were selected for RP model training.

Prognostic impact of pretherapeutic gamma-glutamyltransferase on patients with nasopharyngeal carcinoma.

Background: Gamma-glutamyltransferase (GGT) is a membrane-bound enzyme involved in the metabolism of glutathione. Studies suggested that GGT played an important role in the tumor development, progression, invasion and drug resistance and prognosis. The association between GGT and prognosis of patients with nasopharyngeal carcinoma (NPC) was unknown.

The important role of the receptor for activated C kinase 1 (RACK1) in nasopharyngeal carcinoma progression.

Background: The receptor for activated C kinase 1 (RACK1) is involved in various cancers, but its roles in nasopharyngeal carcinoma (NPC) have not yet been fully elucidated.

Methods: Initially, RACK1 expression was analyzed by immunohistochemistry in NPC and normal nasopharyngeal (NP) tissues. It was also detected by qPCR and Western blot in NPC cells.

High expression of nuclear Snail, but not cytoplasmic staining, predicts poor survival in nasopharyngeal carcinoma.

Background: Transcription factor Snail has been shown to promote tumor progression and metastasis in various cancers. However, its clinical significance in nasopharyngeal carcinoma (NPC) is still scanty. We have explored the clinical significance of Snail expression and its association with patient outcome in NPC.
