As technology continues to advance and artificial intelligence technology is widely applied, ChatGPT (Chat Generative Pre-trained Transformer) is beginning to make its mark in the field of healthcare consultation services. This article summarizes the current applications of ChatGPT in healthcare consultation services, reviewing its roles in four areas: dissemination of disease knowledge, assisting in the understanding of medical information, personalized health education and guidance, and preliminary diagnostic assistance and medical guidance. It also explores the development prospects of ChatGPT in healthcare consultation services, as well as the challenges and ethical dilemmas it faces in this field.
Objective
To detect the expression of transferrin receptor 1 (TfR1) in laryngeal carcinoma, thyroid carcinoma, maxillary sinus carcinoma, and parotid carcinoma, exploring the relationship between the expression of the four cancers and their occurrence and progression.
Methods
A total of 24 specimens of head-neck carcinoma were collected in surgery from April 2015 to March 2017, including 8 cases of laryngeal carcinoma, 8 cases of thyroid carcinoma, 4 cases of maxillary sinus carcinoma, and 4 cases of parotid carcinoma. Fluorescence quantitative polymerase chain reaction technique for TfR1 mRNA and western blot for TfR1 protein was performed in those tumor tissues and their adjacent normal tissues.
Results
The relative expression level of TfR1 mRNA in the tumor tissues of laryngeal carcinoma, thyroid carcinoma, maxillary sinus carcinoma, and parotid carcinoma was 0.078±0.002, 0.065±0.044, 0.076±0.014, 0.067±0.004, respectively; while the relative expression level of TfR1 mRNA in the adjacent normal tissues of the four cancers was 0.021±0.012, 0.011±0.007, 0.017±0.013, 0.028±0.007, respectively. The relative expression level of TfR1 protein in the tumor tissues of laryngeal carcinoma, thyroid carcinoma, maxillary sinus carcinoma, and parotid carcinoma was 0.668±0.206, 0.640±0.066, 0.452±0.095, 0.925±0.221, respectively; while the relative expression level of TfR1 protein in the adjacent normal tissues of the four cancers was 0.359±0.113, 0.424±0.096, 0.280±0.093, 0.519±0.037, respectively. The expression levels of TfR1 mRNA and TfR1 protein in the tumor tissues of the four cancers were all higher than those in their adjacent normal tissues (P<0.05).
Conclusions
The expression levels of TfR1 mRNA and TfR1 protein in the tumor tissues of laryngeal carcinoma, thyroid carcinoma, maxillary sinus carcinoma and parotid carcinoma are up-regulated. TfR1 may be involved in the occurrence and progression of the four cancers, and it may be responsible for tumor proliferation by providing necessary raw materials for the proliferation of tumor cells.
To aggressively proliferate and metastasize, cancer cells are in extreme need of energy supply and nutrients. Therefore, a promising cancer therapy strategy is developed to target its hallmark feature of metabolism. Recent findings revealed the regulatory role of caveolin-1 (Cav-1), a structural protein of caveolae, in cancer metabolism. And low Cav-1 expression in tumor stroma was proved to be a central player of cancer malignant phenotype. Here, we summarized the progressions of studies on Cav-1, mitochondria and cancer metabolism to indicate that the altered metabolism induced by Cav-1 and mitochondria association is a major cause of cancer malignant phenotype.
