Aims: Lung cancer is one of the most common causes of cancer lethality worldwide. Despite recent progress, long-term survival remains poor. The aim of this study was to explore the expression pattern of the thioredoxin superfamily of proteins as potential new diagnostic and/or predictive markers.
Methods And Results: The expression of thioredoxin 1 (Trx1), thioredoxin reductase 1 (TrxR1), the isoforms TrxR1-v.2,3,5, glutaredoxin 1 (Grx1) and glutaredoxin 2 (Grx2) was examined by immunohistochemistry on paraffin-embedded sections from 42 cases of non-small cell lung cancer patients. Additional cases of lung cancer from tissue microarray were examined and the immunoreactivity was compared. All proteins except TrxR1 showed a significant correlation with the degree of differentiation in adenocarcinoma. Trx1 and TrxR1-v.2,3,5 also showed a significant correlation with differentiation in squamous carcinoma. Furthermore, Grx1 and Grx2 showed a clear inverse correlation with proliferation. The proliferation rate was further analysed in vitro in stably transfected Grx2 overproducing cells, showing that the proliferative effect of Grx2 is strictly dependent on subcellular localization.
Conclusions: The thioredoxin family of proteins is important for growth and differentiation of lung cancer cells. The correlation with differentiation and proliferation of these enzymes makes them promising predictive/diagnostic markers.

The widespread application of genome editing to treat and cure disease requires the delivery of genome editors into the nucleus of target cells. Enveloped delivery vehicles (EDVs) are engineered virally derived particles capable of packaging and delivering CRISPR-Cas9 ribonucleoproteins (RNPs). However, the presence of lentiviral genome encapsulation and replication proteins in EDVs has obscured the underlying delivery mechanism and precluded particle optimization.

Rationale: The occurrence of refractory small cell lung cancer (rSCLC) with pancreatic metastasis is a relatively rare clinical condition, which is typically accompanied by a poor prognosis and rapid disease progression.
Patient Concerns: A 65-year-old male farmer from China was diagnosed with limited-stage small cell lung cancer (SCLC) 8 months ago. Following 6 cycles of EP chemotherapy, the patient's tumor response showed partial relief.
Study on mechanism of Spatholobi Caulis in the treatment of the hand-foot skin reaction induced by targeted drug therapy based on network pharmacology and molecular docking: An observational study.

Department of Traditional Chinese Medicine, Shanghai Fourth People's Hospital Affiliated to Tongji University of Medicine, Shanghai, China.
Based on network pharmacology and molecular docking methods, this study explored its active compounds and confirmed its potential mechanism of action against Hand-foot skin reaction induced by tumor-targeted drugs. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and UniProt Database were used to obtain the active ingredients and target proteins of Spatholobi Caulis. All hand-foot skin reaction (HFSR)-related targets were obtained with the help of the Human Gene Database, Online Mendelian Inheritance in Humans (OMIM), DisGeNET and DrugBank databases.

Rationale: Synovial sarcoma (SS) is a rare and highly malignant soft tissue sarcoma. When SS occurs in atypical locations, it can present significant diagnostic challenges. We report a case of paraspinal SS initially misdiagnosed as spinal tuberculosis, highlighting the diagnostic difficulties and the importance of considering SS in the differential diagnosis.
