YBX2 and cancer testis antigen 45 contribute to stemness, chemoresistance and a high degree of malignancy in human endometrial cancer. Sci Rep 2021; 11:4220.

Abstract
Y-box binding protein 2 (YBX2) has been associated with the properties of both germ cells and cancer cells. We hypothesized that YBX2 might contribute to the characteristics of cancer stem cells (CSCs). In this study, we clarified the function of YBX2 in endometrial cancer stem cells. We established a human YBX2-expressing Ishikawa (IK) cell line (IK-YBX2 cells). We analyzed gene expression associated with stemness and isolated SP cells from IK-YBX2 cells. The SP population of IK-YBX2 cells, the expression of ALDH1 and serial sphere-forming capacity were associated with levels of YBX2 expression. IK-YBX2 cells were resistant to anti-cancer drugs. In gene expression analysis, a gene for cancer testis antigen, CT45, was generally overexpressed in IK-YBX2 cells. YBX2-mediated CT45 expression was associated with increased levels of self-renewal capacity and paclitaxel resistance. The level of CT45 expression was enhanced in high-grade and/or advanced stages of human endometrial cancer tissues. We conclude that expression of YBX2 is essential for the stem cell-like phenotype. CT45 contributes to stemness associated with YBX2 and might be related to the progression of endometrial cancer.

Label-Free Mass Spectrometry-Based Plasma Proteomics Identified LY6D, DSC3, CDSN, SERPINB12, and SLURP1 as Novel Protein Biomarkers For Pulmonary Tuberculosis. CURR PROTEOMICS 2021. [DOI: 10.2174/1570164617666191210105122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/22/2022]
Abstract
Aim:
We aimed to identify new plasma biomarkers for the diagnosis of Pulmonary Tuberculosis
(PTB).
Background:
Tuberculosis is an ancient infectious disease that remains one of the major global health problems.
Until now, effective, convenient, and affordable methods for diagnosis of PTB were still lacking.
Objective:
This study focused on constructing a label-free LC-MS/MS-based comparative proteomics
between six tuberculosis patients and six healthy controls to identify Differentially Expressed Proteins
(DEPs) in plasma.
Methods:
To reduce the influences of high-abundant proteins, albumin and globulin were removed from
plasma samples using affinity gels. Then DEPs from the plasma samples were identified using a label-free
Quadrupole-Orbitrap LC-MS/MS system. The results were analyzed by the protein database search algorithm
SEQUEST-HT to identify mass spectra to peptides. The predictive abilities of combinations of host
markers were investigated by General Discriminant Analysis (GDA), with Leave-One-Out Cross-
Validation (LOOCV).
Results:
A total of 572 proteins were identified and 549 proteins were quantified. The threshold for
DEPs was set as adjusted p-value < 0.05 and fold change ≥1.5 or ≤0.6667, 32 DEPs were found. ClusterVis,
TBtools, and STRING were used to find new potential biomarkers of PTB. Six proteins, LY6D,
DSC3, CDSN, FABP5, SERPINB12, and SLURP1, which performed well in the LOOCV method validation,
were termed as potential biomarkers. The percentage of cross-validated grouped cases correctly
classified and original grouped cases correctly classified is greater than or equal to 91.7%.
Conclusion:
We successfully identified five candidate biomarkers for immunodiagnosis of PTB in
plasma, LY6D, DSC3, CDSN, SERPINB12, and SLURP1. Our work supported this group of proteins
as potential biomarkers for PTB, and be worthy of further validation.

Gamage TK, Chamley LW, James JL. Stem cell insights into human trophoblast lineage differentiation. Hum Reprod Update 2016; 23:77-103. [PMID: 27591247 DOI: 10.1093/humupd/dmw026] [Citation(s) in RCA: 50] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2015] [Revised: 06/27/2016] [Accepted: 07/05/2016] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND The human placenta is vital for fetal development, yet little is understood about how it forms successfully to ensure a healthy pregnancy or why this process is inadequate in 1 in 10 pregnancies, leading to miscarriage, intrauterine growth restriction or preeclampsia. Trophoblasts are placenta-specific epithelial cells that maximize nutrient exchange. All trophoblast lineages are thought to arise from a population of trophoblast stem cells (TSCs). However, whilst the isolation of murine TSC has led to an explosion in understanding murine placentation, the isolation of an analogous human TSC has proved more difficult. Consequently, alternative methods of studying human trophoblast lineage development have been employed, including human embryonic stem cells (hESCs), induced pluripotent stem cells (iPS) and transformed cell lines; but what do these proxy models tell us about what is happening during early placental development? OBJECTIVE AND RATIONALE In this systematic review, we evaluate current approaches to understanding human trophoblast lineage development in order to collate and refine these models and inform future approaches aimed at establishing human TSC lines. SEARCH METHODS To ensure all relevant articles were analysed, an unfiltered search of Pubmed, Embase, Scopus and Web of Science was conducted for 25 key terms on the 13th May 2016. In total, 47 313 articles were retrieved and manually filtered based on non-human, non-English, non-full text, non-original article and off-topic subject matter. This resulted in a total of 71 articles deemed relevant for review in this article. OUTCOMES Candidate human TSC populations have been identified in, and isolated from, both the chorionic membrane and villous tissue of the placenta, but further investigation is required to validate these as 'true' human TSCs. Isolating human TSCs from blastocyst trophectoderm has not been successful in humans as it was in mice, although recently the first reported TSC line (USFB6) was isolated from an eight-cell morula. In lieu of human TSC lines, trophoblast-like cells have been induced to differentiate from hESCs and iPS. However, differentiation in these model systems is difficult to control, culture conditions employed are highly variable, and the extent to which they accurately convey the biology of 'true' human TSCs remains unclear, particularly as a consensus has not been met among the scientific community regarding which characteristics a human TSC must possess. WIDER IMPLICATIONS Human TSC models have the potential to revolutionize our understanding of trophoblast differentiation, allowing us to make significant gains in understanding the underlying pathology of pregnancy disorders and to test potential therapeutic interventions on cell function in vitro. In order to do this, a collaborative effort is required to establish the criteria that define a human TSC to confirm the presence of human TSCs in both primary isolates and to determine how accurately trophoblast-like cells derived from current model systems reflect trophoblast from primary tissue. The in vitro systems currently used to model early trophoblast lineage formation have provided insights into early human placental formation but it is unclear whether these trophoblast-like cells are truly representative of primary human trophoblast. Consequently, continued refinement of current models, and standardization of culture protocols is essential to aid our ability to identify, isolate and propagate 'true' human TSCs from primary tissue.
