| Study Title | Ultrahigh-performance liquid chromatography–high-resolution mass spectrometry-based tissue lipidomics study of thymoma and thymic hyperplasia |
| Study Summary | UPLC-HRMS analysis was performed on thymoma and thymic hyperplasia patients. OPLSDA classfication was performed on tumor vs. ANT and DNT samples. Panels of discriminant compounds were identified. The compounds identified in discovery set samples for each binary classification were confirmed by using a set of validation samples, which were run separately. Additionally, paired analysis showed the abundance of discriminant compounds has significant altered in tumor tissues compared to corresponding DNT and ANT samples, reflecting the lipid characteristics related to tumor in situ and cancer cell signaling. |

| Project Title: | Ultrahigh-performance liquid chromatography–high-resolution mass spectrometry-based tissue lipidomics study of thymoma and thymic hyperplasia |
| Project Type: | non-targeted lipidomics analysis |
| Project Summary: | Thymoma is a rare malignant thymic epithelial tumor (TET) with an incidence of about 2 to 4 per million. In this study, we performed nontargeted lipidomic profiling study of tissue samples from 39 patients with thymoma and thymic hyperplasia using UPLC-HRMS. OPLS-DA classification models enabled discrimination of tumor from adjacent noncancerous tissue (ANT) and distant noncancerous tissue (DNT) samples in thymoma with good accuracy, sensitivity, and specificity using 5 discriminant compounds. The discriminant feature panels were verified by external validation sets, revealing characteristic lipid signatures associated with thymoma and showing prospects for entering the next evaluation stage of biomarker discovery for thymoma detection, giving hints to potential treatment targets for the disease. |

Collection:
| Collection ID: | CO003882 |
| Collection Summary: | The patient tissue specimens from 39 patients including the two most prevalent histological subtypes thymoma ("thymo") and thymic hyperplasia ("nodu") were obtained from Beijing Hospital. Primary tumor tissues, paired adjacent non-cancerous tissues (ANT or "side") (within 2 cm apart from tumor edge) and distant normal tissues (DNT or "norm")) ( > 2 cm apart from tumor edge) were surgically resected and frozen at −80 °C until metabolite extraction. The study was approved by the Research Ethics Committee of Beijing Hospital (2019BJYYEC-200-02) and also approved by the Ocean University of China (OUC-HM-2022-002). In the tissue type column of the study design, the abbreviated form "nodu" stands for thymic hyperplasia, "norm" stands for DNT, and "side" stands for ANT. |

Sample Preparation:
| Sampleprep ID: | SP003895 |
| Sampleprep Summary: | Frozen tissue samples of approximately 10-100 mg were thawed on ice, and 1 mL of precooled 80% methanol was added to 100 mg tissue sample.The sample was homogenized (60 Hz, 90 s) in a tissue homogenizer (Jingxin, JX-24, Shanghai, China). After vortexing for 1 min, the mixture was incubated at -80 °C for 4 hours, followed by centrifuging at 14,000 × g for 10 min at 4 °C. The supernatant was transferred to a new tube. To the rest of the sample, 400 μL dichloromethane/ methanol (3:1, v/v) was added for lipid extraction. The sample mixture was then vortexed twice, each time for 30 s, followed by incubation at -80 °C for 30 min. After homogenization (60 Hz, 90 s) and centrifugation of the sample at 14,000 × g for 10 min at 4 °C, the supernatant was collected and dried under a speed vacuum concentrator. |
