AI Article Synopsis
- Recent studies indicate that Y-box binding protein (YB-1) is important for regulating genes that contribute to the progression of carcinoma.
- In this study, YB-1 expression was analyzed in various thyroid neoplasms using immunohistochemical methods, revealing moderate levels in some follicular tumors and papillary carcinoma, but a significant overexpression in 92.9% of anaplastic carcinoma cases.
- The presence of YB-1 was noted in both cytoplasmic and nuclear areas of the cells, suggesting that it may influence both gene transcription and translation processes related to thyroid carcinoma transformation.
Article Abstract
Recent studies have demonstrated that Y-box binding protein (YB-1) regulates the transcription of genes linked to carcinoma progression. In this study, we investigated the expression of this protein in thyroid neoplasms to elucidate its significance. The expression of YB-1 was immunohistochemically investigated using the monoclonal antibody for various thyroid neoplasms. Normal follicles did not overexpress YB-1, and only moderate overexpression of YB-1 was observed in some follicular tumors and papillary carcinoma, especially those of a larger size. In contrast, 92.9% of anaplastic carcinoma strongly overexpressed YB-1. YB-1 immunoreactivity was seen in both cytoplasms and cell nuclei, but the former was more predominant. These findings suggest that YB-1 plays a role in regulating the transcription as well as translation of genes contributing to the anaplastic transformation of thyroid carcinoma.

Dynamic ultrasound-based modeling predictive of response to neoadjuvant chemotherapy in patients with early breast cancer.

Early prediction of patient responses to neoadjuvant chemotherapy (NACT) is essential for the precision treatment of early breast cancer (EBC). Therefore, this study aims to noninvasively and early predict pathological complete response (pCR). We used dynamic ultrasound (US) imaging changes acquired during NACT, along with clinicopathological features, to create a nomogram and construct a machine learning model.

Although CCL17 has been reported to exert a vital role in many cancers, the related studies in the thyroid carcinoma have never reported. As a chemokine, CCL17 plays a positive role by promoting the infiltration of immune cells into the tumor microenviroment (TME) to influence tumor invasion and metastasis. Therefore, this study is aimed to investigate the association of CCL17 level with potential prognostic value on tumor immunity in the thyroid carcinoma (THCA) based on the bioinformatics analysis.

Background: Although thyroid cancer is associated with low mortality rates, significant racial disparities in thyroid cancer outcomes have not been adequately studied in Asia. Moreover, the Asian population consists of different ethnic groups that are not homogeneous. This study aimed to perform a population-based analysis of survival outcomes and prognostic factors in thyroid cancer patients.

Background: Aneuploidy is crucial yet under-explored in cancer pathogenesis. Specifically, the involvement of brain expressed X-linked gene 4 () in microtubule formation has been identified as a potential aneuploidy mechanism. Nevertheless, 's comprehensive impact on aneuploidy incidence across different cancer types remains unexplored.

This study aimed to investigate the effect of Fuzheng Yiai Decoction (FZYA) on epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) drug resistance in lung adenosquamous carcinoma (ASC). The expression of thyroid transcription factor 1 (TTF1) and p63 in tumor cells was observed by immunofluorescence staining. Meanwhile, 25 nude mice successfully inoculated with the human lung ASC cell line NCI-H596 were randomly divided into five groups, namely, the model, gefitinib, low-, medium-, and high-dose FZYA with gefitinib groups.
