Here we show that tissue inhibitors of metalloproteinases (TIMPs) from TIMP-1 to TIMP-4 are differently expressed and regulate yes-associated protein (YAP)/transcriptional co-activator with PDZ binding motif (TAZ) in LS.
These results indicate that dedifferentiation in LS shifts the expression of TIMPs from type 4 to type 1, inducing more aggressive behavior and poor prognosis through YAP/TAZ activation, which can be prognostic markers and therapeutic targets for LS patients.
In the 1432 primary tumors, the 'PARP1-high' samples were associated with younger patients, more frequent locations at the extremities, superficial trunk and head and neck, more leiomyosarcomas and other STSs and less liposarcomas and myxofibrosarcomas, more grade 3, more high-risk CINSARC tumors, and more 'chromosomically instable' tumors.
Herein, we describe an unusual case of a liposarcoma with spindle cell features and a TRIO-TERT fusion transcript identified through next-generation sequencing.
Here we show that tissue inhibitors of metalloproteinases (TIMPs) from TIMP-1 to TIMP-4 are differently expressed and regulate yes-associated protein (YAP)/transcriptional co-activator with PDZ binding motif (TAZ) in LS.
Identification of Coiled-Coil Domain-Containing Protein 180 and Leucine-Rich Repeat-Containing Protein 4 as Potential Immunohistochemical Markers for Liposarcoma Based on Proteomic Analysis Using Formalin-Fixed, Paraffin-Embedded Tissue.
Both a PDGFR inhibitor (CP-673451) and a Wnt/ β-catenin inhibitor (ICG-001) had potent inhibitory effects on liposarcoma cells, suggesting their potential application in liposarcoma treatment.
The immunohistochemical and RT-PCR analyses of 68 liposarcoma specimens revealed a significant high expression of HMGA1, at the protein and RNA levels, both in myxoid and dedifferentiated liposarcoma subtypes compared with differentiated ones.
In the present study, we reported that SBF-1, a steroidal glycoside, inhibited the growth of cultured highly malignant human liposarcoma SW872-S cells in vitro and in vivo.
PER1 rs3027178 was associated with a reduced predisposition only in liposarcoma subgroup (32%). rs7602358 located upstream PER2 was significantly associated with liposarcoma survival (HR: 1.98; 95% CI 1.02-3.85; P = 0.04).

Intensely positive vimentin immunohistochemistry, along with large quantities of Oil Red O-positive lipid droplets within the neoplastic cells, were supportive of our diagnosis of liposarcoma.
Moreover, HIF-2α expression was linked to a good survival benefit in some cancers (B-cell lymphoma and lung adenocarcinoma: OS, multiple myeloma: DSS, breast cancer: distant metastasis-free survival, liposarcoma: distant recurrence-free survival) (all HRs < 1, Ps < 0.05).
Using both patient plasma samples and cell lines, we demonstrate here that miR-25-3p and miR-92a-3p are secreted by liposarcoma cells through extracellular vesicles and may be useful as potential biomarkers of disease.
Since the membrane Cavin-2 protein was reported to play a key role in caveolae formation of adipocytes, in this work we have used a multidisciplinary approach to investigate its expression in liposarcoma (LPS), an adipocytic soft tissue sarcoma affecting adults.
