Innovation: Wu Xiaojian's team from the Sixth Affiliated Hospital of Sun Yat-sen University and Tan Jing's team from Sun Yat-sen University Cancer Center's Center for Cancer Prevention and Treatment have collaborated to reveal the therapeutic potential of PLK1 inhibitors in colorectal cancer, and elucidate the pharmacological mechanism of the combined use of PLK1 inhibitors and oxaliplatin, namely PLK1 inhibitors can inhibit the transcriptional activity of c-MYC on CDC7, leading to down-regulation of CDC7 protein levels, and finally proposed a targeted inhibition of the PLK1-MYC-CDC7 signaling pathway can effectively improve oxaliplatin sensitivity
.
Keywords: colorectal cancer, chemotherapy resistance, PLK1, CDC7 how to overcome chemotherapy resistance has always been a hot and difficult problem in the field of cancer research
.
Finding therapeutic targets based on multi-omics sequencing data, and verifying drug trials in the model of patient tumor origin, is one of the effective methods for developing targeted drugs
.
Recently, Wu Xiaojian's research group from the Sixth Affiliated Hospital of Sun Yat-sen University and Tan Jing's research group from Sun Yat-sen University Cancer Center have published the title: Inhibition of the PLK1-coupled cell cycle machinery overcomes resistance to oxaliplatin in colorectal in Advanced Science (IF: 16.
8).
Cancer research paper
.
The study used omics sequencing data to integrate PLK1, a potential related target of colorectal cancer chemotherapy resistance, and validated drug trials on multiple patient tumor-derived models, and systematically explored PLK1 inhibitors in colorectal cancer.
Therapeutic mechanism in
.
The results of this study found that the combined use of PLK1 inhibitors can significantly improve the anti-tumor effect of oxaliplatin, which provides new treatment ideas for patients with colorectal cancer who are resistant to chemotherapy or tumor recurrence
.
Targeted inhibition of the PLK1-MYC-CDC7 signaling pathway can effectively improve oxaliplatin sensitivity.
The research team integrated and analyzed large-scale colorectal cancer patient sample data and found that PLK1 may be a potential drug target for colorectal cancer
.
It was also found that PLK1 was highly expressed in tumor tissues of patients who relapsed after chemotherapy, suggesting that it may be related to chemotherapy resistance (Figure 1)
.
Figure 1 The high expression of PLK1 in tumor tissues of patients who relapsed after chemotherapy.
In order to verify the efficacy of the drug, the research team conducted drug efficacy experiments on colorectal cancer cell lines, patient tumor-derived organoid models and PDX models, confirming that the targeted drug can improve The efficacy of oxaliplatin provides sufficient preclinical research data for clinical translational therapy (Figure 2)
.
Figure 2 Targeted therapy has significant efficacy in organoids and PDX models.
Finally, through the integrated analysis of RNA-seq and ChIP-seq data, it is found that the PLK1-MYC-CDC7 signaling pathway plays an important role in regulating colorectal cancer chemotherapy resistance It provides a clear pharmacological mechanism for the clinical application of PLK1 inhibitors (Figure 3)
.

In summary, the research team explored the therapeutic potential of PLK1 inhibitors in colorectal cancer, and clarified the pharmacological mechanism of the combined use of PLK1 inhibitors and oxaliplatin, namely PLK1 inhibitors can inhibit the transcriptional activity of c-MYC on CDC7, leading to down-regulation of CDC7 protein levels, and finally proposed a targeted inhibition of the PLK1-MYC-CDC7 signaling pathway can effectively improve oxaliplatin sensitivity
