Description

Product for detecting liver cancer or prognosis of liver cancer based on PRSS35 pathway and liver cancer therapeutic agent based on PRSS35 pathway
Technical Field
The invention relates to the field of liver cancer detection, in particular to a product for detecting liver cancer or prognosis of liver cancer based on a PRSS35 pathway and a liver cancer therapeutic agent based on the PRSS35 pathway.
Background
Liver cancer is one of the most common malignant tumors seriously harming human health, and according to the cancer report of China in 2019, primary liver cancer is the current cause of death of the 4 th common malignant tumor and the 2 nd tumor in China, and seriously threatens the life and health of people in China. Primary liver cancer mainly comprises 3 different pathological types including hepatocellular carcinoma (Hepatocellular carcinoma, HCC), intrahepatic bile duct carcinoma (Intrahepatic cholangiocarcinoma, ICC) and HCC-ICC, and 3 are greatly different in pathogenesis, biological behaviors, tissue morphology, treatment method, prognosis and the like, wherein HCC accounts for 85% -90% (therefore, the patent takes HCC as a main study object, and the later-mentioned liver cancers are all HCC). However, the current treatment mode of liver cancer is mainly surgery and TACE interventional therapy, and the medicine is usually only used as an auxiliary treatment means; diagnosis and treatment means are mainly various imaging examinations, and biomarker detection such as AFP and DFP detection is usually only used as an auxiliary means because a plurality of negative patients exist. Therefore, the key molecular mechanism in the liver cancer occurrence and development process is further clarified, and the method is particularly critical for developing new liver cancer therapeutic drugs and early diagnosis markers.
Numerous reports have been made today to demonstrate that many proteins and their mediated molecular pathways in liver cells are altered during the development of liver cancer to meet the demands of tumor cell survival and proliferation. In recent years, with the development and perfection of sequencing technology and mass spectrometry technology, research on molecular mechanism of liver cancer gradually shifts from small flux to large flux, for example, in 2019 He Fu beginner, by applying high-flux unlabeled proteomics technology, liver cancer tissues of 110 liver cancer patients and proteomes of paracancerous tissues are compared, intracellular protein molecules with significantly changed protein levels when liver cancer occurs are systematically analyzed, and 110 liver cancer patients are subjected to more careful molecular typing according to the changes, so that the method has important significance and value for treating and diagnosing liver cancer.
Meanwhile, the liver is one of the most main endocrine organs of the human body, and the secretory protein group of the liver is obviously changed in the development process of liver cancer. The secretory proteome is a generic term for proteins secreted by cells into the extracellular environment, and secreted proteins are involved in the important roles of intercellular signaling among multicellular organisms. Therefore, the secreted protein has important significance for diagnosis and treatment of liver cancer, and is more suitable for being used as a target for detection and targeted treatment because of the characteristic that the secreted protein of the liver exists in a large amount in blood. However, since the collection and analysis of secreted proteins have a series of technical difficulties, the research of intracellular molecules and signal pathways has been relatively delayed. However, with the development of mass spectrometry technology, researchers have made a series of progress by analyzing and researching cell line level secreted proteome and serum proteome, and 21 secreted proteins have been used as diagnosis and treatment targets for various cancers and have entered 26 clinical trials. However, there is a large number of gaps and unknowns in this field, compared to the extent of the study of intracellular molecules and from the total number of secreted proteins.

The following is a brief description: the experimental group cells (HepG 2-PRSS 35) or the Control group cells (HepG 2-EV Control) were cultured at a ratio of 2X 10 4 The cells in the corresponding wells are digested and blown into single cells every 24 hours, the cell dilution suspension is dripped into a blood cell counting plate after the bromophenol blue is diluted to a certain multiple, the cell number is counted under a microscope, and finally the cell number of each well is obtained by multiplying the dilution multiple, and the experiment is repeated for 3 times in parallel.
Results: as shown in FIG. 3A, compared with the Control cell HepG2-EV Control (EV curve in the figure), the proliferation of the liver cancer cell highly expressing the exogenous PRSS35 has no significant change (PRSS 35 curve in the figure).
Analysis of results: the cell count experiment result shows that at the cell level, the over-expression of PRSS35 has no obvious effect on the proliferation of liver cancer cells, and the effect of PRSS35 on liver cancer is likely to depend on the microenvironment in vivo.
(2) In vivo experiments: mouse heterogeneous subcutaneous transplantation tumor experiment
The method comprises the following steps: preparing sufficient quantities of HepG2-EV and HepG2-PRSS35 cells; preparing an immunodeficient mouse Balb/c-nude mouse, weighing and recording the day before injection, and randomly separating cages; directly sucking the cells into a 1ml syringe by using a needle, and injecting the cells into the back of the mouse subcutaneously; the size of the subcutaneous transplantation tumor of the mice was measured after 9 days of injection, until day 30, and the mice were killed and the subsequent experiments were performed.
Results: as shown in fig. 3B, PRSS35 did not affect proliferation of subcutaneous engraftment tumors in immunodeficient mice.
Analysis of results: PRSS35 did not affect proliferation of immunodeficient mice subcutaneous transplants, suggesting that the effect of PRSS35 on liver cancer according to the present invention is likely to depend on the immune microenvironment in vivo.
(3) In vivo experiments: spontaneous liver cancer induction experiment of mice
The method comprises the following steps: pBL-CMV-lenti-puro-EV (shown as SEQ ID N0: 3), pBL-lenti-puro-RFP (shown as SEQ ID N0: 4) and pBL-CMV-lenti-puro-YAP5SA (shown as SEQ ID N0: 5) plasmids (the tail vein high pressure injection of pBL-CMV-lenti-puro-YAP5SA plasmids can induce spontaneous liver cancer of mice); amplifying cDNA sequence of PRSS35 CDs region by PCR, constructing purified CDs sequence of PRSS35 into pBL-CMV-lenti-puro-EV expression vector to obtain PRSS35 over-expression plasmid pBL-CMV-lenti-puro-PRSS35; pBL-CMV-lenti-puro-RFP was used as a group, and pBL-CMV-lenti-puro-RFP and pBL-CMV-lenti-puro-YAP5SA were co-injected as a group; pBL-CMV-lenti-puro-PRSS35 and pBL-CMV-lenti-puro-YAP5SA were co-injected as a group, and an equal amount of plasmid was injected into 5 ICR mice of 4 weeks of age by tail vein high pressure injection, respectively. Mice were dissected 3 months after injection and observed for intrahepatic tumor formation and tumor size.
Results: as shown in fig. 3C, the RFP group did not form tumors, whereas the yap5sa+prss35 group had significantly less tumors than the yap5sa+rfp group.
Analysis of results: experimental results show that spontaneous liver cancer caused by YAP5SA can be remarkably inhibited by high expression of PRSS35 in liver. From fig. 3A, 3B and 3C, it was found that PRSS35 did not affect proliferation of liver cancer cells at the cell line level, did not affect tumor proliferation in immunodeficient mice, and significantly inhibited development of liver cancer in immunocompetent mice.
2. Investigation of the upstream regulatory mechanism of PRSS35
The method comprises the following steps: in liver cancer cell lines, mRNA and protein level changes of PRSS35 were detected by WB and qPCR with/without overexpression of ERa, exogenous presence/absence of added estrogen. The primer pair for qPCR detection comprises sequences shown as SEQ ID No. 0:1 and SEQ ID No. 0:2.
Results: as shown in fig. 4A and 4B, fig. 4A is a graph of results at protein level, and fig. 4B is a graph of results at mRNA level, where both estrogen and ERa can up-regulate mRNA and protein levels of PRSS35.
Analysis of results: the demonstration that PRSS35 is subject to transcriptional regulation by the ERa pathway suggests that intervention of the present invention in PRSS35 to treat liver cancer may be carried out by the ERa pathway.
3. Screening for substrate molecules of PRSS35
The method comprises the following steps: preparation of 5X 10 each of the cells of the experimental group (PLC-PRSS 35) and the cells of the Control group (PLC-EV Control) 6 Collecting cells, and extracting mRNA in half for transcriptome sequencing;
the other half is extracted protein for proteomics detection. And selecting a molecular listing list with significantly reduced protein level and no significantly changed mRNA level under the condition of over-expressing PRSS35, taking the molecular listing list as a candidate substrate molecule of the PRSS35, and selecting a molecule with the highest mRNA level/protein level value for verification by an immunoblotting experiment (Western blot).
Results: the results of the combined transcriptomic and proteomic analysis are shown in FIG. 5A, and the molecular IGFBP1 with the highest mRNA/protein level was selected for immunoblotting, and was indeed down-regulated by PRSS35, as shown in FIG. 5B.
Analysis of results: confirming that IGFBP1 is a downstream substrate of PRSS35, suggesting that intervention of PRSS35 by the present invention to treat liver cancer may be practiced by directly modulating IGFBP1 and downstream thereof; it is also suggested that IGFBP1 and its downstream molecules of the invention have potential as targets for liver cancer diagnosis. Meanwhile, the invention discovers from a screened substrate list that the substrate contains a plurality of molecules related to immunity, which suggests that the PRSS35 inhibits the molecular mechanism of liver cancer possibly related to immunity.
The above examples are only preferred embodiments of the present invention, and are merely for illustrating the present invention, not for limiting the present invention, and those skilled in the art should not be able to make any changes, substitutions, modifications and the like without departing from the spirit of the present invention.
