5 results about "Malignant Solid Neoplasm" patented technology

A gene delivery system and applications thereof in the technical field of biological medicines that is particularly useful in the preparation of drugs for treatment of tumors are disclosed. The gene delivery system and applications relate to technology for inducing the differentiation of malignant tumor cells into mature cells, in which regulating the expression of HNF4 alpha protein in the malignant tumor cells using messenger ribonucleic acid, the malignant phenotype of the malignant solid tumor cells is inhibited, and the effective treatment of the malignant solid tumors is achieved. The gene delivery system and applications are therefore applicable to a method of preparing a drug for treating malignant solid tumors and to a method of treating a patient having a malignant solid tumor.

The invention relates to an ultrasonic response type copper molybdate nano material as well as a preparation method and application thereof. The chemical formula of the nano material is HCu1. 5MoO5. The preparation method comprises the following steps: mixing a molybdenum source, urea and a copper source in water, cooling, crystallizing, and carrying out ultrasonic treatment. Compared with the prior art, the nano material can synchronously generate active oxygen and controllably release copper ions at a tumor site under the accurate control of exogenous ultrasound, and efficiently subvert the copper steady state in tumor cells through the biaxial synergistic effect of'efflux inhibition 'and'internal supply enhancement', so that copper death is specifically induced, and the tumor cell apoptosis is inhibited. And anti-tumor immune response is synergistically activated, so that effective application in treatment of bladder cancer by inducing copper death, especially in treatment of malignant solid tumors such as bladder cancer and pancreatic cancer, is realized.

Circulating tumor cells (CTCs) are associated with metastasis of malignant solid tumors in a patient. Presented here is evidence that CTCs exhibit cell cycle phase variability and that there is a strong correlation between the number of CTCs in a mitotic cell cycle phase and the prospects for long term survival of the subject from which the cells were obtained. Also presented herein are methods of determining the mitotic cell cycle phase of CTCs from a patient having cancer and using the information in grading malignant solid tumors and predicting the likelihood of survival of the patient.
