Thoracic Radiotherapy Improves the Survival in Patients With -Mutated Oligo-Organ Metastatic Non-Small Cell Lung Cancer Treated With Epidermal Growth Factor Receptor-Tyrosine Kinase Inhibitors: A Multicenter, Randomized, Controlled, Phase III Trial.

Purpose: This multicenter, randomized, phase III clinical trial (Northern Radiation Oncology Group of China-002) focused on patients with oligo-organ metastatic non-small cell lung cancer (NSCLC) who have epidermal growth factor receptor () mutations. We aimed to investigate whether first-line concurrent thoracic radiotherapy (TRT) and EGFR-tyrosine kinase inhibitors (TKIs), compared with TKIs alone, could achieve better survival.

Materials And Methods: The patients in the TKI plus TRT group received 60 Gy to primary lung tumor and positive regional lymph nodes.

Transcription factor STAT4 counteracts radiotherapy resistance in breast carcinoma cells by activating the MALAT1/miR-21-5p/THRB regulatory network.

Considering the limited research and the prevailing evidence of STAT4's tumor-suppressing role in breast carcinoma (BC) or in breast radiotherapy (RT) sensitivity requires more in-depth exploration. Our study delves into how STAT4, a transcription factor, affects BC cell resistance to radiotherapy by regulating the MALAT1/miR-21-5p/THRB axis. Bioinformatics analysis was performed to predict the regulatory mechanisms associated with STAT4 in BC.

Field-tuned quantum effects in a triangular-lattice Ising magnet.

We report thermodynamic and neutron scattering measurements of the triangular-lattice quantum Ising magnet TmMgGaO in longitudinal magnetic fields. Our experiments reveal a quasi-plateau state induced by quantum fluctuations. This state exhibits an unconventional non-monotonic field and temperature dependence of the magnetic order and excitation gap.

Anti-PD-L1 Antibody Enhances T Cell Immune Responses and Reduces Resistance of Breast Cancer Cells to Radiotherapy.

Immune escape is a frequent occurrence, which limits the duration of antitumor immune responses to radiotherapy. Here, we aimed to ascertain the roles and underlying mechanisms of programmed death ligand 1 (PD-L1) in tolerance of breast cancer (BC) to radiotherapy. We first quantified microRNA-21 (miR-21) and PD-L1 expression in BC tissues and cells, followed by identification of the interactions between miR-21, PD-L1, and programmed cell death protein 4 (PDCD4).

Trends in the Use of Sphingosine 1 Phosphate in Age-Related Diseases: A Scientometric Research Study (1992-2020).

Objectives: This study was designed to explore the intellectual landscape of research into the application of sphingosine 1 phosphate (S1P) in age-related diseases and to identify thematic development trends and research frontiers in this area.

Methods: Scientometric research was conducted by analyzing bibliographic records retrieved from the Web of Science (WOS) Sci-Expanded Database dated between 1900 and 2020. Countries, institutions, authors, keyword occurrence analysis, and cooperation network analysis were performed using the CiteSpace and VOSviewer software.

PD1 tumor associated macrophages predict poor prognosis of locally advanced esophageal squamous cell carcinoma.

Tumor associated macrophages are the most abundant cancer immune cells. However, little was known about the identity of CD68PD1 macrophages as well as the contributions in the prognosis of esophageal squamous cell carcinoma (ESCC). Immunofluorescence, flowcytometry and RT-PCR were used to analysis PD1 macrophages in ESCC.

Prognostic biological factors of radiation pneumonitis after stereotactic body radiation therapy combined with pulmonary perfusion imaging.

Radiation pneumonitis (RP) is one of the most common dose-limiting toxicity syndromes in patients with thoracic malignant tumors receiving radiotherapy. The present study aimed to identify biological factors for the prediction of RP. Pulmonary perfusion imaging is capable of reflecting the differential functional activity of various regions of the lung, and in the present study, radiotherapy plans that were established on the basis that pulmonary perfusion images have high biological conformality, which may identify regions vulnerable to RP to spare them from radiation.

[Correlations between Ape1/Ref-1, ICAM-1 and IL-17A Levels in Serum and Radiation Pneumonitis for Local Advanced Non-small Cell Lung Cancer Patients].

Background: The main manifestations of radiation pneumonitis are injury of alveolar epithelial and endothelial cells, abnormal expression of cytokines, abnormal proliferation of fibroblasts and synthesis of fibrous matrix. The occurrence of radiation pneumonitis is associated with multiplecytokine level abnormality. These cytokines can also be used as bio-markers to predict the occurrence of radiation pneumonitis.

MiR-135a-5p represses proliferation of HNSCC by targeting .

This research aimed to explore the role of miR-135a-5p in head and neck squamous cell carcinoma (HNSCC) cells and its influence on cell viability. Moreover, we aimed to compare effects of miR-135a-5p and miR-494 in HNSCC, which was found to repress expression in oral cancer. The association between miR-135a-5p and was confirmed by green fluorescence protein reporter assay and qRT-PCR.
