Pleural mesothelioma is a rare cancer of the pleura, the lining of the lungs. It is the most common form of cancer caused by asbestos.

Mesothelin-targeted replication-defective recombinant lentivirus CAR-T transgenic carrier as well as establishment method and application thereof

The invention discloses a Mesothelin-targeted replication-defective recombinant lentivirus CAR-T transgenic carrier which comprises a pronucleus replicon pUC Ori sequence for plasmid replication, an amicillin resistance gene AmpR containing sequence for mass amplification of target strain, virus replicon SV40Ori sequence for enhancing replication in eukaryocyte, a lentivirus packaging cis-element for lentivirus packaging, a ZsGreen1 green fluorescent protein for green fluorescence expression of eukaryocyte, an IRES ribosome combination sequence for joint transcriptional expression of protein, a human EF1(alpha) promoter for the eukaryotic transcription of chimeric antigen receptor gene, a chimeric antigen receptor for forming a second-generation CAR or third-generation CAR integrating identification, transfer and start, and an eWPRE element for improving the transgenic expression efficiency. Moreover, the invention also discloses an establishment method and application of the carrier. In the invention, the secretion of cell factors and the in-vitro killing effect of CAR-T cells can be remarkably enhanced, and the effect of clinical treatment of malignant pleural mesothelioma and pancreatic cancer is outstanding.

The invention discloses a novel mouse in-situ pleural mesothelioma model and an establishment method thereof. The establishment method comprises the following steps of 1, taking 90 BLAB/C nude mice as an experimental group and 30 control groups, and uniformly putting the experimental group and the control groups into an incubator for normal culture; 2, under the condition that BLAB/C nude mice breathe, heartbeat and the like are normal, anesthetizing the mice and fixing the mice on an animal operating table in a supine position for experiment; and 3, at the intersection point of the left rib 5/6 intercostal space and the left chest wall anterior axillary line of the mouse, using microscopic forceps to lift and pull the skin at the intersection point, then using a 22G sterile sharp needle head to break the skin at the intersection point, then using a 30G sterile blunt pillow to break the wall layer pleura along the broken opening. The tumor transplantation method provided by the invention is applicable to orthotopic transplantation of pleural tumors. The growth mode, the invasion ability and the tumor metastasis effect of the pleural tumor can be restored to the maximum extent, and a good mouse model is constructed for studying the pleural tumor.

Preparation method of bio-modified castor protein and application of bio-modified castor protein to preparation of drug for treating malignant pleural mesothelioma

The invention discloses a preparation method of a bio-modified castor protein and application of the bio-modified castor protein to preparation of a drug for treating malignant pleural mesothelioma. The preparation method of the bio-modified castor protein comprises the following steps of puffing and smashing a bio-modified castor insect body in a normal-temperature puffing device; then, adding the smashed bio-modified castor insect body into an expanding solvent system extracting device to extract a crude bio-modified castor protein; collecting a solution containing the crude bio-modified castor protein, and filtering by using a micropore filter to remove impurities; carrying out ultrafiltration treatment by using an ultrafilter, and collecting a bio-modified castor protein ultrafiltration solution; dissolving the ultrafiltration solution into acetonitrile, separating by using a solid-phase extraction column, and collecting an eluted component; dissolving the eluted component into a solvent system, and separating and purifying by using an ultrasonic stationary wave preparative liquid chromatography; and preparing freeze-dried protein powder by using a vacuum freeze-drying machine, wherein the freeze-dried protein powder can be used for preparing the drug for treating malignant pleural mesothelioma. A bio-modified castor protein preparation prepared by using the preparation method is stable in quality, clear in structure, distinct in pharmacology and remarkable in curative effect.
