SATB2 : Special AT-rich sequence binding protein 2 (SATB2) is a SATB2, when used in combination with the marker Keratin 20, may identify more than 95 % of 2 (SATB2) expression is sensitive but may not be specific for osteosarcoma

Reduction of SATB2 or N-cadherin resulted in NF-κB inactivation, which led to impaired osteosarcoma sphere formation and tumor cell proliferation [54].

Methods: Immunostaining of SATB2 was performed in 47 cases of osteosarcomas, 5 Osteosarcoma (OSA) is the most common primary malignant bone tumor, usually arising in the long bones of children and young adults. There are different subtypes of OSA, among which we find the conventional OS (also called medullary or central osteosarcoma) which has a high grade of malignancy and an incidence of 80%. 2020-01-31 · The lncRNAs RP1-261G23.7, RP11-69E11.4 and SATB2-AS1 are a novel clinical signature for predicting recurrent osteosarcoma.

Author information: (1)Trauma Center, State Key Laboratory of Trauma, Burns and Combined Injury, Institute of Surgery Research, Daping Hospital, Army Medical University, No.10 ChangjiangZhi Road, Yuzhong District, Chong The SATB2-AS1 is a 3197-bp lncRNA on chromosome 2.

Feb 11, 2021 Bone - Osteosarcoma - general. Negative for SATB2; Contains a characteristic gene rearrangement (EWSR1-ETS transcription factor). SATB2 is a reliable osteoblastic marker for differential diagnosis of osteosarcoma and non-osteoid sarcoma, although with a limited role in separating Atypical mitoses, necrosis. Immunohistochemistry: SATB2, S100 if cartilage present.

However, the molecular mechanisms that regulate OS metastatic spread are largely SATB2 positivity was present in 30/50 (60%) cases lacking osteosarcoma, predominantly as patchy moderate staining within undifferentiated sarcoma. No cases showed SATB2 positivity in chondrosarcoma or rhabdomyosarcoma components.

SATB2 is a reliable osteoblastic marker for differential diagnosis of osteosarcoma and non-osteoid sarcoma, although with a limited role in separating osteosarcoma from non-malignant osteoblastic lesions.

Feb 11, 2021 Bone - Osteosarcoma - general. Negative for SATB2; Contains a characteristic gene rearrangement (EWSR1-ETS transcription factor).

SATB2 is a highly sensitive marker for osteosarcomatous differentiation in gynecologic tract carcinosarcoma, and is also highly specific when used to differentiate osteosarcoma from chondrosarcoma and rhabdomyosarcoma elements in these tumors. SATB2 is a reliable osteoblastic marker for differential diagnosis of osteosarcoma and non-osteoid sarcoma, although with a limited role in separating osteosarcoma from non-malignant osteoblastic lesions. SATB2 is commonly expressed in osteosarcomas. Although apparently being a valuable diagnostic marker for differentiating between small cell osteosarcoma (SCO) and other small round cell tumors of bone, for instance Ewing sarcoma family of tumors (ESFT), it has not been tested in a large series of ES ….

CONCLUSIONS: SATB2 plays an important role in regulating osteosarcoma stem cell-like properties and tumor growth. The combination of conventional chemotherapy and metformin may be a promising therapeutic strategy for os-teosarcoma patients.

High SATB2 expression in osteosarcoma patient samples was associated with poor clinical outcome. N-cadherin was one critical downstream target gene of SATB2 that mediated the stem cell-like phenotype. Reduction of SATB2 or N-cadherin resulted in NF-kB inactivation, which led to impaired osteosarcoma sphere formation and tumor cell proliferation.

2018-07-04 · Primary bone tumors are rare, but osteosarcoma (OS) is the fourth commonest non-hematological primary neoplasm of the bone in the adolescence, and the other three commonest neoplasms, in descending order, are leukemia, brain tumors, and lymphoma. The commonest presenting complaints are swelling and aches. These tumors cannot be diagnosed without the help of radiology.

SATB2 is a reliable osteoblastic marker for differential diagnosis of osteosarcoma and non-osteoid sarcoma, although with a limited role in separating Nov 11, 2020 However, SATB2 positivity is not specific for osteosarcoma and cannot differentiate it from other primary bone sarcomas, which has been well SATB2 : Special AT-rich sequence binding protein 2 (SATB2) is a SATB2, when used in combination with the marker Keratin 20, may identify more than 95 % of 2 (SATB2) expression is sensitive but may not be specific for osteosarcoma The exact cause of osteosarcoma is unknown. osteoblasts and malignant osteoids IHC:SATB2 and AKP are positive, TP53 alteration and MDM2 amplification Feb 2, 2021 Metformin reduces SATB2-mediated osteosarcoma stem cell-like phenotype and tumor growth via inhibition of N-cadherin/NF-kB signaling. SATB2 and pluripotency-associated gene expression in osteosarcoma CSCs were analyzed using. qRT-PCR and Western blotting.

Small round cell osteosarcoma is a very rare type of osteosarcoma, histologically mimicking other small round cell malignancies of bone, most notably Ewing sarcoma. To distinguish small cell osteosarcoma from other primary small cell malignancies of bone, we evaluated the immunohistochemical (IHC) expression of CD99 and SATB2, a marker of osteoblastic differentiation.

SATB2 is a marker of osteoblastic differentiation in benign and malignant mesenchymal tumours. Although SATB2 is not specific for osteosarcoma, it has the potential to be a useful adjunct in some settings, particularly in the distinction between hyalinized collagen and osteoid. SATB2, strongly expressed in oral osteosarcoma, fibroosseous lesions, and central giant cell granuloma, is not a reliable diagnostic marker. However, SATB2 can distinguish between induced neoplastic bone and reactive bone tissue. Targeting SATB2 as an alternative therapy should be investigated.
