Tropomodulin 3 (TMOD3) has been increasingly studied in tumors in recent years. This study is the first to report that TMOD3 is highly expressed in ovarian cancer and is closely associated with platinum resistance and immune infiltration. These results could help improve the therapeutic outcomes for ovarian cancer.

¹College of Computer Science and Technology, and Key Laboratory of Symbolic Computation and Knowledge Engineering of Ministry of Education, Jilin University, ²School of Biology and Engineering, Guizhou Medical University

Here, we introduce a protocol for converting transcriptomic data into a mqTrans view, enabling the identification of dark biomarkers. While not differentially expressed in conventional transcriptomic analyses, these biomarkers exhibit differential expression in the mqTrans view. The approach serves as a complementary technique to traditional methods, unveiling previously overlooked biomarkers.

Establishment of A Mouse Model of Aqueous Deficiency Dry Eye

Meng Zhang^*1,2, Xiaoyu Tian^*1,2, Yiming Wu³, Liying Zhang^1,2, Lingli Zhang^1,2, Xueer Zheng^1,2, Shangkun Ou^1,2, Hao Gu^1,2

¹Department of Ophthalmology, the Affiliated Hospital of Guizhou Medical University, ²School of Clinical Medicine, Guizhou Medical University, ³Department of Biomedical Sciences, School of Infection, Inflammation and Immunology, College of Medicine and Health, University of Birmingham

Here, we present a method to establish a mouse model of aqueous-deficient dry eye by excising the extraorbital and infraorbital lacrimal glands and evaluate the changes in the ocular surface in aqueous deficiency dry eye.
