Method for culturing bladder cancer organs in vitro

The invention discloses a method for culturing bladder cancer organs in vitro. The method comprises the following steps: manufacturing a gas-liquid interaction culture system, namely manufacturing a uniformly paved rat tail collagen supporting layer on the surface of a porous culture membrane in a Transwell upper chamber; re-suspending fresh in-vitro bladder cancer tissues by using a rat tail collagen solution, uniformly mixing, adding the obtained mixture onto the rat tail collagen supporting layer, and then putting the rat tail collagen supporting layer into an incubator at 37 DEG C to solidify so as to obtain a rat tail collagen layer containing the bladder cancer tissues; adding an organoid culture medium into a Transwell lower chamber, and enabling the liquid level of the culture medium to be lower than the rat tail collagen layer containing bladder cancer tissues; and carrying out passage and cryopreservation. The culture success rate of the bladder cancer organoid is remarkablyincreased, the bladder cancer organoid with reserved immune cells can be obtained through culture, operation is easy, the utilization rate of tumor tissue is high, and great significance and value areachieved for bladder cancer drug screening research.

Application of target up-regulation PAR-4 gene small ribonucleic acid (RNA) in preparing bladder cancer resisting drugs

The invention provides application of target up-regulation PAR-4 gene small ribonucleic acid (RNA) in preparing bladder cancer resisting drugs. The nucleotide sequence of the target up-regulation PAR-4 gene small RNA is composed of six positive sense strands and negative sense strands of 21 nucleotides. The 3' end of each strand is provided with two nucleotides in suspension mode (generally dTdT, and the 19 nucleotides in the middle are paired.). The target up-regulation PAR-4 gene small RNA comprises sa RNA of different sequences. By means of expression of target up-regulation PAR-4 genes in the bladder cancer cells, the small RNA can restrain tumor cell activity, induces cell apoptosis, and further can be applied to preparation of bladder cancer resisting drugs. The application of target up-regulation PAR-4 gene small RNA in preparing the bladder cancer resisting drugs is simple in operation of preparing the small RNA, low in cost, small in using amount, capable of achieving good activation effect when the transfection concentration is 50nM and accurate in activation action. The mRNA and protein level of the target genes are both improved. In addition, the sa RNA can induce genes to express without damaging completeness of gene groups, thereby being safe to use.

Assembloid - 3D mimetic tissue structure based on patient- derived multiple cell types and method of manufacturing the same

The present invention relates to a 3 dimensional mimetic tissue structure—“Assembloid” based on patient-derived multiple cell types to develop next generation organoid technology serving as a novel platform for new drug development and a disease model and a method of manufacturing the same, and more particularly, to a stem cell- or tumor cell-based 3D multicellular mimetic tissue structure manufactured by reconstituting epithelial or tumor cells with various cellular components of a microenvironment such as stromal cells, vascular cells, immune cells or muscle cells based on three-dimensional (3D) bioprinting, and a method of manufacturing the same. As the stem cell- or tumor cell-based 3D multicellular mimetic tissue structure containing the major factors of a tissue microenvironment, such as stromal cells, vascular cells, immune cells and muscle cells, designed according to the present invention is confirmed to mimic physiological and pathological characteristics of tissue in the body better than conventional organoids, normal and tumor assembloids may be used as a new platform for new drug development and a disease model. More specifically, together with 3D bioprinting technology, it is expected that in vitro bladder tissue and bladder tumor tissue are effectively used as a platform to develop precise and personalized therapeutic options for bladder related diseases including bladder cancer.

Implant agent treating for solid tumor

The invention relates to a sustained-release implant for treating a solid tumor, which is characterized in that: the sustained-release implant contains an effective anticancer amount of bortezomib and sustained-release excipients. The solid tumor includes brain tumor, liver cancer, lung cancer, oesophagus cancer, gastric cancer, breast cancer, pancreatic cancer, thyroid cancer, nasopharyngeal cancer, ovarian cancer, endometrial cancer, cervical cancer, renal cancer, prostate cancer, bladder cancer, colon cancer, rectal cancer, skin cancer, head and neck cancer and primary or secondary cancer, caruncle or carcinosarcoma rooted at a peripheral nervous system, mucosa, glands, blood vessels, bone tissues and lymph nodes. The sustained-release excipients are mainly a biological polymer which is dissoluble and can be degraded and absorbed, in the degradation and absorption process of which carmustine is sustainedly released to part of the tumor, thus the entire toxicity of the carmustine is significantly reduced while an effective medicine consistency is maintained on part of the tumor. That the sustained-release implant is implanted inside part of the tumor can not only reduce the entire toxicity of the carmustine but also enhance the medicine consistency on part of the tumor, thereby increasing the curing effect of non-operative therapeutics such as chemotherapeutic drugs and radiotherapy.
