This study evaluated a comparison between the essential oils of leaf and flower derived from Spilanthes paniculata targeting the SCC9 oral cell lines using in vitro and in silico approaches. The anticancer activity was performed through an MTT assay, apoptosis assays using annexin V and orospheres formation assays. Molecular docking was performed between five selected phytocompounds against the p53 protein by using AutoDock 4.2.6 software. The results confirmed that the flower essential oil significantly reduced the cell viability in a dose-dependent manner, with an IC<sub>50</sub> value of 113.95 µg/mL. The apoptosis assays showed that the flower essential oil was approximately 2.5 times more effective in inducing early apoptosis at 50 µg/mL compared to the essential oil of the leaf. The orosphere formation assays further confirmed the anticancer potential of the flower essential oil. Spathulenol exhibited strong hydrogen bonding with the p53 protein. The ADMET prediction tools were used to predict the in silico pharmacokinetics and drug-like properties of the phytoconstituents.

Erythropoietin-producing hepatocellular A2 (EPHA2) is overexpressed in many cancers, including cervical cancer, and the mechanism by which it regulates cervical cancer progression is not yet fully understood. Exosomes are extracellular vesicles that carry information in the form of biomolecules, deliver it to the recipient cell, and play a vital role in cellular communication. 17β-Estradiol is the natural female steroid hormone with the greatest estrogenic activity, and it induces cell death in cancer. In this study, we investigated the function of EPHA2 in cervical cancer migration and immunomodulation and the presence of EPHA2 in the cervical cancer serum-derived exosome. A knockdown of EPHA2 (KD-EPHA2) in cervical cancer reduces cancer cell migration by regulating the CD113/Ezrin pathway. Furthermore, EPHA2 exhibited significant involvement in immunomodulation by orchestrating IL-6-mediated signalling cascades, including the AKT-mTOR and JAK-STAT pathways. Immune infiltration analysis revealed a correlation between EPHA2 expression in cervical cancer and the infiltration of various immune cell populations.

They are key in coordinating the assembly and help keep the correct structure, location, and function of the kinetochore, a proteinaceous structure vital for ensuring proper chromosome segregation during cell division. Abnormalities in centromere structure can lead to aneuploidy or chromosomal instability, which have been implicated in various diseases, including cancer. Accordingly, abnormalities in centromeres, such as structural rearrangements and dysregulation of centromere-associated proteins, disrupt gene function, leading to uncontrolled cell growth and tumor progression. For instance, altered expression of CENP-A, CENP-E, and others such as BUB1, BUBR1, MAD1, and INCENP, have been shown to ascribe to centromere over-amplification, chromosome missegregation, aneuploidy, and chromosomal instability; this, in turn, can culminate in tumor progression. These centromere abnormalities also promoted tumor heterogeneity by generating genetically diverse cell populations within tumors. Advanced techniques like fluorescence in situ hybridization (FISH) and chromosomal microarray analysis are crucial for detecting centromere abnormalities, enabling accurate cancer classification and tailored treatment strategies. Researchers are exploring strategies to disrupt centromere-associated proteins for targeted cancer therapies. Thus, this review explores centromere abnormalities in cancer, their molecular mechanisms, diagnostic implications, and therapeutic targeting.

To substantiate this, we have investigated BBOX1 expression and its clinical relevance in HB, and explored how BBOX1 might inhibit the occurrence and development of HB.

The presence of cell apoptosis, cell cycle changes, and reactive oxygen species (ROS) was assayed using flow cytometry. Compared with normal tissues, the expression of BBOX1 in hepatoblastoma tissues was notably decreased. Dysregulated expression of BBOX1 was indicated as a prognostic risk factor closely linked to clinical stag of patients with HB. Furthermore, following BBOX1 overexpression, cell proliferation and migration are decreased, the cell cycle is arrested, and ROS are attenuated.
