liposarcoma/tyrosine

The expression of tyrosine kinase receptors is attracting major interest in human and veterinary oncological pathology because of their role as targets for adjuvant therapies. Little is known about tyrosine kinase receptor (TKR) expression in canine liposarcoma (LP), a soft tissue sarcoma. The aim

Therapeutic progress in well-differentiated/dedifferentiated liposarcoma (WDLPS/DDLPS) is hampered by lack of relevant experimental models, thereby limiting comprehensive molecularly based investigations. Our goal is to bridge this experimental gap by establishing and characterizing an in vitro/in

BACKGROUND The rarity of dedifferentiated liposarcoma (DDLPS) and the lack of experimental DDLPS models limit the development of novel therapeutic strategies. Pazopanib (PAZ) is a tyrosine kinase inhibitor that is approved for the treatment of non-adipocytic advanced soft tissue sarcoma. The

Soft tissue sarcomas (STS) represent a diverse group of histologic subtypes with targetable molecular alterations, often treated as a single disease. Sunitinib malate is a multitargeted receptor tyrosine kinase inhibitor active in other solid tumors carrying similar alterations (i.e., imatinib

Well-differentiated liposarcoma (WDLPS) and dedifferentiated liposarcoma (DDLPS) are closely related tumors commonly characterized by MDM2/CDK4 gene amplification, and lack clinically effective treatment options when inoperable. To identify novel therapeutic targets, we performed targeted genomic

OBJECTIVE The aim of this study was to analyze receptor tyrosine kinases (RTK) and their downstream signaling activation profile in myxoid liposarcomas (MLS) by investigating 14 molecularly profiled tumors: 7 naive and 7 treated with conventional chemotherapy/radiotherapy or the new drug

BACKGROUND Myxoid/round cell liposarcoma is the second most common subtype of liposarcoma. Chemotherapy and radiotherapy have a limited efficacy for treating advanced myxoid/round cell liposarcoma, with relatively serious side effects. METHODS We herein present a 68-year-old Chinese woman initially

The fused in sarcoma/translocated in liposarcoma (FUS/TLS) gene was initially identified as a component of a fusion pro-oncogene resulting from a chromosomal translocation seen in liposarcomas. FUS/TLS belongs to a sub-family of RNA binding proteins, encoding an N-terminal

BACKGROUND Myxoid liposarcoma is a relatively common malignant soft tissue tumor, characterized by a (12;16) translocation resulting in a FUS-DDIT3 fusion gene playing a pivotal role in its tumorigenesis. Treatment options in patients with inoperable or metastatic myxoid liposarcoma are relatively

Pazopanib, a novel tyrosine kinase inhibitor, is an effective therapeutic agent for patients with advanced soft tissue sarcoma. Here we report three patients with recurrent retroperitoneal liposarcoma who were treated with pazopanib. Case 1: A 54-year-old male received three courses of combined

Introduction: Liposarcomas (LPS) are a heterogeneous group of adipocytic soft tissue sarcomas with limited treatment options in the advanced/metastatic setting. Pazopanib is a multi-target tyrosine kinase inhibitor (TKI) with anti-angiogenic and antitumorigenic properties. Whilst targeted

BACKGROUND The FUS-DDIT3 fusion oncogene encodes an abnormal transcription factor that has a causative role in the development of myxoid/round-cell liposarcomas (MLS/RCLS). We have previously identified FLT1 (VEGFR1) as a candidate downstream target gene of FUS-DDIT3. The aim of this study was to

BACKGROUND Liposarcoma, the most common soft tissue tumor, is understudied cancer, and limited progress has been made in the treatment of metastatic disease. The Achilles heel of cancer often is their kinases that are excellent therapeutic targets. However, very limited knowledge exists of

Binding of fibroblast growth factor (FGF) to the high affinity receptor-1 (FGFR-1) leads to activation of its endogenous tyrosine kinase activity. A number of substrates for the FGFR-1 kinase have been identified. Among those, FGF receptor-substrate-2 (FRS-2) was identified by virtue of its

A human orthologue of the Saccharomyces cerevisiae YVH1 protein-tyrosine phosphatase is able to rescue the slow growth defect caused by the disruption of the S. cerevisiae YVH1 gene. The human YVH1 gene is located on chromosome 1q21-q22, which falls in a region amplified in human liposarcomas. The
