Abstract
Using the licochalcone moiety as a lead compound scaffold, 16 novel imidazole-chalcone derivatives were designed and synthesized as microtubule protein polymerization inhibitors. The proliferation inhibitory activities of the derivatives against SiHa (human cervical squamous cell carcinoma), C-33A (human cervical cancer), HeLa (human cervical cancer), HeLa/DDP (cisplatin-resistant human cervical cancer), and H8 (human cervical epithelial immortalized) cells were evaluated. Compound 5a exhibited significant anticancer activity with IC50 values ranging from 2.28 to 7.77 μM and a resistance index (RI) of 1.63, while showing minimal toxicity to normal H8 cells. When compound 5a was coadministered with cisplatin, the RI of cisplatin to HeLa/DDP cells decreased from 6.04 to 2.01, while compound 5a enhanced the fluorescence intensity of rhodamine 123 in HeLa/DDP cells. Further studies demonstrated that compound 5a arrested cells at the G2/M phase, induced apoptosis, reduced colony formation, inhibited cell migration, and inhibited cell invasion. Preliminary mechanistic studies revealed that compound 5a decreased the immunofluorescence intensity of α-/β-tubulin in cancer cells, reduced the expression of polymerized α-/β-tubulin, and increased the expression of depolymerized α-/β-tubulin. Additionally, the molecular docking results demonstrate that compound 5a can interact with the tubulin colchicine binding site and generate multiple types of interactions. These results suggested that compound 5a has anticancer effects and significantly reverses cervical cancer resistance to cisplatin, which may be related to its inhibition of microtubule and P-glycoprotein (P-gp) activity.

Abstract
Aim: To investigate the relationship between potential abnormal epigenetic modification and immune cell infiltration in patients with cervical carcinoma. Materials & methods: RNA expression profiles from The Cancer Genome Atlas database were used to explore the relationship between key biomarkers and tumor-infiltrating immune cells and for clinical specimen validation. Results: Two nomogram models were developed, one with specific ceRNA and the other based on biological markers of related tumor-infiltrating immune cells. Moreover, a key biomarker (RIPOR2), which was significantly relevant to CD8 T cells. Conclusion: RIPOR2 and CD8 T cells play a crucial role in the development and progression of cervical carcinoma, suggesting their potential as markers for guiding future therapeutic strategies.

Abstract
Cervical cancer is an important topic in the study of global health issues, ranking fourth among women's cancer cases in the world. It is one of the nine major cancers that China is focusing on preventing and treating, and it is the only cancer that can be prevented through vaccination. Systematic and effective screening for human papilloma (HPV) infection, which is closely linked to the development of cervical cancer, can reduce cervical cancer incidence and mortality. In this paper, an electrochemical sensor was designed to detect HPV 16 using dual-signal amplification. An APTES-modified glassy carbon electrode was used for improved stability. Gold nanoparticles and a chain amplification reaction were combined for signal amplification. The limit of detection (LOD) of this electrochemical sensor was 1.731 × 10-16 mol/L, and the linear response of the target detector range was from 1.0 × 10-13 mol/L to 1.0 × 10-5 mol/L (R2 = 0.99232). The test of serum sample recovery showed that it has good anti-interference, and the performance of all aspects was improved to different degrees compared with the previous research from the team. The designed sensor is centered around the principles of low cost, high sensitivity and stability, which provides new ideas for the future development of cervical cancer prevention and electrochemical biosensors.
