Abstract
Lung adenocarcinoma (LUAD) is a significant planetary health challenge with its high morbidity and mortality rate, not to mention the marked interindividual variability in treatment outcomes and side effects. There is an urgent need for robust systems biomarkers that can help with early cancer diagnosis, prediction of treatment outcomes, and design of precision/personalized medicines for LUAD. The present study aimed at systems biomarkers of LUAD and deployed integrative bioinformatics and machine learning tools to harness gene expression data. Predictive models were developed to stratify patients based on prognostic outcomes. Importantly, we report here several potential key genes, for example, PMEL and BRIP1, and pathways implicated in the progression and prognosis of LUAD that could potentially be targeted for precision/personalized medicine in the future. Our drug repurposing analysis and molecular docking simulations suggested eight drug candidates for LUAD such as heat shock protein 90 inhibitors, cardiac glycosides, an antipsychotic agent (trifluoperazine), and a calcium ionophore (ionomycin). In summary, this study identifies several promising leads on systems biomarkers and drug candidates for LUAD. The findings also attest to the importance of integrative bioinformatics, structural biology and machine learning techniques in biomarker discovery, and precision oncology research and development.

Abstract
We have developed a targeted nano-drug delivery system that effectively harnesses the anti-tumor properties of trifluoperazine (TFP), while concurrently mitigating its side effects on the central nervous system. The manufacturing process entailed the preparation of mesoporous silica nanoparticles (MSN-NH2), followed by the loading of trifluoperazine into the pores of MSN-NH2 and then surface modification with polyethylene glycol (PEG) and anisamide (AA), resulting in the formation of TFP@MSN@PEG-AA (abbreviated as TMPA) nanoparticles. In vitro and in vivo anti-tumor activity and hemolysis experiments showed that TMPA had an excellent safety profile and a good anti-tumor effect. Importantly, the drug content of the TMPA nanoparticle group was found to be significantly lower than that of the TFP group in the mouse brain tissue as determined by High Performance Liquid Chromatography (HPLC) detection. Therefore, the developed drug delivery system achieved the goal of maintaining TFP's anti-tumor action while avoiding its negative effects on the central nervous system.

Chai Y, Chu RYK, Hu Y, Lam ICH, Cheng FWT, Luo H, Wong MCS, Chan SSM, Chan EWY, Wong ICK, Lai FTT. Association between cumulative exposure periods of flupentixol or any antipsychotics and risk of lung cancer. COMMUNICATIONS MEDICINE 2023; 3:126. [PMID: 37752185 PMCID: PMC10522572 DOI: 10.1038/s43856-023-00364-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Accepted: 09/18/2023] [Indexed: 09/28/2023] Open
Abstract
BACKGROUND Preclinical evidence suggests that certain antipsychotic medications may inhibit the development of lung cancer. This study aims to investigate the association between incident lung cancer and different cumulative exposure periods of flupentixol or any antipsychotics. METHODS Using electronic health records from the Hospital Authority in Hong Kong, this nested case-control study included case participants aged 18 years or older with newly diagnosed lung cancer after initiating antipsychotics between January 1, 2003, and August 31, 2022. Each case was matched to up to ten controls of the same sex and age, who were also antipsychotic users. Multivariable conditional logistic regression models were conducted to quantify the association between lung cancer and different cumulative exposure times of flupentixol (0-365 days [ref]; 366-1825 days; 1826+ days) and any antipsychotics (1-365 days [ref]; 366-1825 days; 1826+ days), separately. RESULTS Here we show that among 6435 cases and 64,348 matched controls, 64.06% are males, and 52.98% are aged 65-84 years. Compared to patients with less than 365 days of exposure, those with 366-1825 days of exposure to flupentixol (OR = 0.65 [95% CI, 0.47-0.91]) and any antipsychotics (0.42 [0.38-0.45]) have a lower risk of lung cancer. A decreased risk is observed in patients who have 1826+ days of cumulative use of any antipsychotics (0.54 [0.47-0.60]). CONCLUSIONS A reduced risk of lung cancer is observed in patients with more than one year of exposure to flupentixol or any antipsychotics. Further research on the association between lung cancer and other antipsychotic agents is warranted.

Moura C, Vale N. The Role of Dopamine in Repurposing Drugs for Oncology. Biomedicines 2023; 11:1917. [PMID: 37509555 PMCID: PMC10377204 DOI: 10.3390/biomedicines11071917] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 07/04/2023] [Accepted: 07/04/2023] [Indexed: 07/30/2023] Open
Abstract
Dopamine is a neurotransmitter that plays an important role within the brain by regulating a wide variety of cognitive and emotional processes. In cancer, its role is distinct and uncertain, but it is characterized by the interaction with its receptors that may be in the tumor cells; we have examples of different types of cancer with this characteristic, of which breast and colon cancer stand out. It is believed that dopamine and some of its receptors also influence other cellular processes such as cell proliferation, survival, migration, and invasion. The potential of these receptors has allowed the exploration of existing drugs, originally developed for non-oncological purposes, for the possible treatment of cancer. However, regarding the repurposing of drugs for cancer treatment, the role of dopamine is not so straightforward and needs to be clarified. For this reason, this review intends to present concepts associated with twelve drugs reused for oncology based on dopamine and its receptors. Some of them can behave as antagonists and inhibit tumor cell growth leading to cell death. Attention to this group of drugs may enhance the study of other pharmacological conditions such as signaling pathways related to cell proliferation and migration. Modulation of these pathways using drugs originally developed for other conditions may offer potential therapeutic opportunities in oncology. It is important to note that while the repurposing of oncology drugs based on dopamine signaling is promising, further studies are still needed to fully understand the mechanisms involved and determine the clinical efficacy and safety of these approaches.

Mahapatra KK, Mishra SR, Dhiman R, Bhutia SK. Stonin 2 activates lysosomal-mTOR axis for cell survival in oral cancer. Toxicol In Vitro 2023; 88:105561. [PMID: 36702439 DOI: 10.1016/j.tiv.2023.105561] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 01/10/2023] [Accepted: 01/16/2023] [Indexed: 01/24/2023]
Abstract
Aberrant expression of various genes is associated with the progression of oral squamous cell carcinoma. Stonin 2, an endocytic protein, has a prominent role in clathrin-associated endocytosis. Its position in oral cancer is still unknown. Here, we report that STON2 expression increases with an increase in the grade of the oral cancer tissue. Further, STON2 overexpressed cells possess a higher rate of proliferation and migraton in oral cancer cells. STON2 helps maintain lysosomal functions by preserving the lysosomal membrane integrity. It activates the Akt-mTOR axis and retains the mTOR on the membrane of the lysosomes. Further, we have identified an inhibitor of STON2, i.e., Trifluoperazine dihydrochloride (TFP), which targets the lysosomal axis by disrupting the Akt-mTOR pathway and causes lysosomal membrane permeabilization. Intererstingly, TFP shows a decrease in cell vaibility on the oral cancer cells and it was observed that cell viability is restored in TFP-treated STON2 overexpressed cells. Moreover, the lysosomal activity and the Akt-mTOR expression are restored in STON2 overexpressed cells co-treated with TFP, establishing TFP targets STON2 to showcase its anti-cancer effects in oral cancer. In conclusion, STON2 might serve as a potential biomarker in oral cancer, and its inhibition could functions as a novel anti-cancer mechanims against oral cancer.
