Aim: The comparative study of antitumor action of peripheral blood lymphocytes (PBL) and lymphokin-activated killer cells (LAK) on autologous cell of chemoresistant and chemosensitive human soft tissue sarcomas and tumors of epithelial origin.
Materials And Methods: Tumor explants (15 samples of soft tissue sarcomas, 10 samples of cervical and ovarian carcinomas) were cultivated with autologous lymphocytes in double diffusion chambers. Evaluation of the results was done on the basis of morphological criteria of explants growth.
Results: The results have shown that in the patients with the resistant soft tissue sarcomas and carcinomas LAK possess more pronounced antitumor action, than non-activated lymphocytes, whilst PBL possess higher antitumor action on sensitive epithelial tumors than that on soft tissue sarcoma.
Conclusion: LAK possess antitumor action toward chemoresistant tumors of different origin and localization.

Hepatocellular carcinoma(HCC) has a high mortality and morbidity rate and seriously jeopardizes human life. Chemicals and chemotherapeutic agents have been experiencing problems such as side effects and drug resistance in the treatment of HCC, which cannot meet the needs of clinical treatment. Therefore, finding novel low-toxicity and high-efficiency anti-hepatocellular carcinoma drugs and exploring their mechanisms of action have become the current problems to be solved in the treatment of HCC.

Extracting natural active ingredients from plants is an effective way to develop and screen modern drugs. Psoralea corylifolia is a leguminous plant whose seeds have long been used as a Traditional Chinese Medicine to treat psoriasis, rheumatism, dermatitis, and other diseases. To date, several main compounds, including coumarins, flavonoids, monoterpene phenols, and benzofurans, have been identified from the seeds of Psoralea corylifolia.

Lung cancer represents a significant global health burden, with non-small cell lung cancer (NSCLC) being the most common subtype. The current standard of care for NSCLC has limited efficacy, highlighting the necessity for innovative treatment options. Lidocaine, traditionally recognized as a local anesthetic, has emerged as a compound with potential antitumor and anti-inflammatory capabilities.

Laetrile is a semi-synthesis product of amygdalin, whereas amygdalin is a naturally occurring substance in many plants. Both compounds have a nitrile functional group that, when activated by the intestinal enzyme β-glucosidases, releases hydrogen cyanide.

Tumor heterogeneity plays a pivotal role in tumor progression and resistance to clinical treatment. Single-cell RNA sequencing (scRNA-seq) enables us to explore heterogeneity within a cell population and identify rare cell types, thereby improving our design of targeted therapeutic strategies. Here, we use a pan-cancer and pan-tissue single-cell transcriptional landscape to reveal heterogeneous expression patterns within malignant cells, precancerous cells, as well as cancer-associated stromal and endothelial cells.
