Exosomal circ_0032704 confers sorafenib resistance to hepatocellular carcinoma and contributes to cancer malignant progression by modulating the miR-514a-3p/PD-L1 pathway. Ann Gastroenterol Surg 2024; 8:507-520. [PMID: 38707229 PMCID: PMC11066485 DOI: 10.1002/ags3.12772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 12/20/2023] [Accepted: 12/26/2023] [Indexed: 05/07/2024] Open
Abstract
Purpose This study aims to explore the role of circ_0032704 in sorafenib-resistant hepatocellular carcinoma (HCC). Methods The expression of circ_0032704, miR-514a-3p, and programmed death-ligand 1 (PD-L1) mRNA was detected by quantitative real-time PCR (qPCR). The expression of multidrug resistant-related proteins, migration/invasion-related proteins, exosome-related proteins, and PD-L1 protein was detected by western blot. Cell viability was detected by CCK-8 assay. Cell proliferation, migration, and invasion were assessed by EdU assay, wound healing assay, and transwell assay. The binding between miR-514a-3p and circ_0032704 or PD-L1 was verified by RIP assay, pull-down assay, and dual-luciferase reporter assay. Cell- or serum-derived exosomes were isolated and identified by TEM and NTA. Xenograft models were established to determine the effect of circ_0032704 on drug resistance in vivo. Results Circ_0032704 was overexpressed in sorafenib-resistant HCC tissues and cells. Circ_0032704 knockdown reduced sorafenib resistance in HCC cells and inhibited cell proliferation, migration, and invasion of sorafenib-resistant HCC cells, while these effects were reversed by PD-L1 overexpression. We found that circ_0032704 positively regulated PD-L1 expression via targeting miR-514a-3p. Exosomes with circ_0032704 inhibition reduced sorafenib resistance in HCC cells and inhibited cell proliferation, migration, and invasion of sorafenib-resistant HCC cells. Exosomes with circ_0032704 inhibition also inhibited tumor growth in vivo. The expression of circ_0032704 in exosomes was stable and possessed diagnostic value. Conclusion Circ_0032704 enhanced sorafenib resistance in HCC and promoted the malignant development of sorafenib-resistant HCC. Circ_0032704 could be transported by exosomes, and exosomal circ_0032704 had diagnostic value.

Abstract
INTRODUCTION Hepatocellular carcinoma is the prevalent primary liver cancer, a silent disease that killed 782,000 worldwide in 2018. Multimodal deep learning is the application of deep learning techniques, fusing more than one data modality as the model's input. PURPOSE A computer-aided diagnosis system for hepatocellular carcinoma developed with multimodal deep learning approaches could use multiple data modalities as recommended by clinical guidelines, and enhance the robustness and the value of the second-opinion given to physicians. This article describes the process of creation and evaluation of an algorithm for computer-aided diagnosis of hepatocellular carcinoma developed with multimodal deep learning techniques fusing preprocessed computed-tomography images with structured data from patient Electronic Health Records. RESULTS The classification performance achieved by the proposed algorithm in the test dataset was: accuracy = 86.9%, precision = 89.6%, recall = 86.9% and F-Score = 86.7%. These classification performance metrics are closer to the state-of-the-art in this area and were achieved with data modalities which are cheaper than traditional Magnetic Resonance Imaging approaches, enabling the use of the proposed algorithm by low and mid-sized healthcare institutions. CONCLUSION The classification performance achieved with the multimodal deep learning algorithm is higher than human specialists diagnostic performance using only CT for diagnosis. Even though the results are promising, the multimodal deep learning architecture used for hepatocellular carcinoma prediction needs more training and test processes using different datasets before the use of the proposed algorithm by physicians in real healthcare routines. The additional training aims to confirm the classification performance achieved and enhance the model's robustness.

Correlation between Imaging Features and Pathological Stages of Primary Lung Tumors Based on Nanocontrast Agents. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2021; 2021:2343299. [PMID: 34790250 PMCID: PMC8592732 DOI: 10.1155/2021/2343299] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 10/14/2021] [Accepted: 10/18/2021] [Indexed: 12/05/2022]
Abstract
As one of the conventional methods of lung cancer detection, computed tomography (CT) usually requires the use of contrast agents to enhance the imaging effect. Conventional iodine contrast agents have poor signal-to-noise ratio and are prone to adverse reactions. It is necessary to find more effective and safe contrast agents for CT scans. The gold nanoparticles with secondary electron effect and photoelectric absorption effect can prolong the display time of the patient's blood circulation after being injected into the patient's body, which makes the nanocontrast agent a research hotspot in the field of CT imaging. In this study, ultrasmall gold nanoclusters with a diameter of about 5 nm were used as the contrast agent in CT scans. It was found that CT scans based on nanocontrast agents can obtain high-quality lung cancer imaging images, and the patient has no obvious adverse reactions. When observing the CT image, it was found that the stage of lung cancer patients can be clearly distinguished through the CT scan image. When analyzing the consistency of CT imaging and pathological classification, the Kappa value was 0.810, indicating that the two have a high degree of consistency. Therefore, this study believes that the imaging characteristics of primary lung tumors based on nanocontrast agents are highly correlated with their pathological types.

LI-RADS to categorize liver nodules in patients at risk of HCC: tool or a gadget in daily practice? Radiol Med 2020; 126:5-13. [PMID: 32458272 DOI: 10.1007/s11547-020-01225-8] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Accepted: 05/12/2020] [Indexed: 10/25/2022]
Abstract
PURPOSE To determine the effectiveness of liver reporting and data system (LI-RADS) to diagnose hepatocellular carcinoma (HCC) and to retrospectively evaluate its impact on the adopted therapeutic strategy. MATERIALS AND METHODS Preoperative imaging of 40 of 350 patients (median age 66, 31 M/9 F) submitted to liver resection for suspected HCC, between January 2008 and August 2019, has been retrospectively analyzed by two radiologists with different expertise, according to CT/MRI LI-RADS® v2018, both blinded to clinical and pathological results and untrained to using aforementioned scoring system. RESULTS The perfect agreement between the readers was about 62.5% (25/40) (Cohen k: 0.41), better for LR-5 category (16/25) and higher in magnetic resonance imaging (MRI) investigations (68%; 13/19), which has been demonstrated the modality of choice for diagnosis of high probable and certain HCC, with arterial phase hyperenhancement as the most sensitive and accurate major feature. Compared to final histology, LR4 and LR5 scores assigned by senior radiologist reached sensitivity, specificity, positive and negative predictive values (PPV, PNV) and diagnostic accuracy of 90,9%, 29,0%, 93,8%, 62,5% and 87,5%, respectively, slightly higher than junior's ones. Misdiagnosis of HCC was done by both radiologists in the same two patients: 1 primary hepatic lymphoma (PHL) and 1 regenerative liver nodule (RLN). If LI-RADS would have been applied at the time of pre-surgical imaging, treatment planning would be modified in 10% of patients (4/40); the patient scheduled as LR-3 and finally resulted a focal nodular hyperplasia would have avoided liver resection. CONCLUSIONS Application of LI-RADS, especially on MRI, may provide a more accurate evaluation of suspected HCC. PHL and RLN are the Achille's heels according to our experience.

Upregulation of microRNA-140-3p inhibits epithelial-mesenchymal transition, invasion, and metastasis of hepatocellular carcinoma through inactivation of the MAPK signaling pathway by targeting GRN. J Cell Biochem 2019; 120:14885-14898. [PMID: 31044454 DOI: 10.1002/jcb.28750] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Revised: 12/28/2018] [Accepted: 01/09/2019] [Indexed: 02/06/2023]
Abstract
Invasion and metastasis in hepatocellular carcinoma (HCC) results in poor prognosis. Human intervention in these pathological processes may benefit the treatment of HCC. The aim of the present study is to elucidate the mechanism of miR-140-3p affecting epithelial-mesenchymal transition (EMT), invasion, and metastasis in HCC. Microarray analysis was performed for differentially expressed genes screening. The target relationship between miR-140-3p and GRN was analyzed. Small interfering RNA (siRNA) against granulin (GRN) was synthesized. EMT markers were detected, and invasion and migration were evaluated in HCC cells introduced with a miR-140-3p inhibitor or mimic, or siRNA against GRN. A mechanistic investigation was conducted for the determination of mitogen-activated protein kinase (MAPK) signaling pathway-related genes and EMT markers (E-cadherin, N-cadherin, and Vimentin). GRN was highlighted as an upregulated gene in HCC. GRN was a target gene of miR-140-3p. Elevation of miR-140-3p or inhibition of GRN restrained the EMT process and suppressed the HCC cell migration and invasion. HCC cells treated with the miR-140-3p mimic or siRNA-GRN exhibited decreased GRN expression and downregulated the expressions of the MAPK signaling pathway-related genes, N-cadherin, and Vimentin but upregulated the expression of E-cadherin. GRN silencing can reverse the activation of the MAPK signaling pathway and induction of EMT mediated by miR-140-3p inhibition. Taken together, the results show that miR-140-3p confers suppression of the MAPK signaling pathway by targeting GRN, thus inhibiting EMT, invasion, and metastasis in HCC.

KIAA1199 promotes sorafenib tolerance and the metastasis of hepatocellular carcinoma by activating the EGF/EGFR-dependent epithelial-mesenchymal transition program. Cancer Lett 2019; 454:78-89.

Abstract
Patients with advanced hepatocellular carcinoma (HCC) will almost always develop acquired tolerance after sorafenib therapy, and the molecular mechanism of sorafenib tolerance remains poorly characterized. Here, using our established sorafenib-resistant HCC cell and xenograft models, we identified a novel gene, KIAA1199, which was markedly elevated among the differentially expressed genes involved in sorafenib tolerance. Moreover, elevated expression of KIAA1199 was positively correlated with a high risk of recurrence and metastasis and advanced TNM stage in HCC patients. Functionally, loss- and gain-of-function studies showed that KIAA1199 promoted the migration, invasion, and metastasis of sorafenib-resistant HCC cells. Mechanistically, KIAA1199 is required for EGF-induced epithelial-mesenchymal transition (EMT) in sorafenib-resistant HCC cells by aiding in EGFR phosphorylation. In summary, our data uncover KIAA1199 as a novel sorafenib-tolerant promoting gene that plays an indispensable role in maintaining sorafenib-resistant HCC cell metastasis.

Abstract
The use of ultrasonography (US) as an imaging modality in medicine has spread across almost every clinical specialty. This diffusion is based on the simplicity, accessibility, portability and affordability of the technique producing real-time high-resolution images using non-ionising radiation. On the other hand, this trend also extended the technique to settings other than healthcare, such as public facilities, private houses or remote sites. This tendency can be observed worldwide, from developing countries to prestigious medical schools and tertiary referral hospitals. Furthermore, point-of-care US (POCUS), i.e., US executed at the patient's bedside to obtain real-time objective information with diagnostic and clinical monitoring purposes or to guide invasive procedures, has been incorporated in many specialties. In gastroenterology, despite the essential role of endoscopy, clinical practice is highly dependent on non-endoscopic imaging techniques. However, as in other specialties, the indications of US in gastroenterology have been increasing steadily, covering a broad range of conditions. In response to the generalised employment of US by non-radiologists, institutions such as the European Federation of Societies for Ultrasound in Medicine and Biology and the Royal College of Radiologists issued recommendations to ensure high-quality practice. These theoretical and practical requisites include performing a certain number of examinations and mandatory skills in order to achieve certification to execute unsupervised US. Therefore, there is a need for modern gastroenterology to include US as a basic skill in its clinical practice. To ensure the provision of high-quality US, adequate instruction of future specialists should be guaranteed by the gastroenterology departments and required in the residency training programme.

Abstract
Introduction Despite some new treatment possibilities, the improvement in survival rate for hepatocellular carcinoma (HCC) patients is still poor due to late diagnosis. The aim of this study was to investigate the diagnostic sensitivity and specificity of protein induced by vitamin K absence or antagonist-II (PIVKAII), Glypican-3 (GP3), Cystatin B (CSTB), squamous cell carcinoma antigen 1 (SCCA1) and hepatocyte growth factor (HGF) as potential tumour markers for HCC in patients with alcoholic liver cirrhosis (ALC) using imaging techniques (MSCT and MRI) as reference standards. Patients and methods Eighty-three participants were included: 20 healthy volunteers, 31 patients with ALC and 32 patients with HCC. Peripheral blood sampling was performed for each participant, and serum concentrations of PIVKAII, GP3, CSTB, SCCA1 and HGF were determined using commercial ELISA kits. Results Only serum concentrations of PIVKAII were significantly higher in HCC patients as compared with ALC and healthy controls (cut-off: 2.06 µg/L; AUC: 0.903), whereas individual diagnostic performance of other individual compounds was inadequate. The ‘best’ combination of tumour markers in our study includes all tested markers with AUC of 0.967. Conclusion While novel diagnostic tumour markers are urgently needed, the examined potential tumour markers, with the exception of PIVKAII seem to be inadequate for diagnosing HCC in ALC. Furthermore, probably the future is in finding the best optimal combination of tumour markers for diagnosing HCC based on cost-effectiveness.
