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.

In addition, SATB2-AS1 is specifically involved in the PI3K-Akt signaling pathway, which can affect the epithelial–mesenchymal transition in numerous ways to influence tumor aggressiveness . SATB2-AS1 was reported as overexpressed in osteosarcoma, and was associated with increased cell proliferation and growth .

SATB2 is a marker of osteoblastic differentiation in benign and malignant mesenchymal tumors. Head and neck 1. SATB2 acts as a tumor suppressor in laryngeal squamous cell carcinoma wherein loss of expression was associated with recurrence and high tumor grade. (36,58) 2. CONCLUSIONS: SATB2 is a marker of osteoblastic differentiation in benign and malignant mesenchymal tumours.

Forty‐five of 48 (94%) osteosarcomas showed nuclear immunoreactivity for SATB2 (all whole‐slide sections showed expression). Dehydroandrographolide Inhibits Osteosarcoma Cell Growth and Metastasis by Targeting SATB2-mediated EMT Anti-Cancer Agents in Medicinal Chemistry, Vol. 19, No. 14 Satb2 regulates proliferation and nuclear integrity of pre-osteoblasts For confirmation, immunohistochemistry for SATB2, a marker of osteoblastic differentiation, was carried out. SATB2 was diffusely immunopositive in the nuclei of tumor cells [Figure 2f]. A final diagnosis of an osteoblastic osteosarcoma was made. The patient was advised chemo and radiotherapy and was discharged. She was subsequently lost to Recently, nuclear SATB2 expression has been shown to be useful to demonstrate osteoblastic differentiation in soft tissue and bone tumors, particularly when the distinction between hyalinized collagen and osteoid is challenging.

doi: 10.1309/AJCPWW2URZ9JKQJU. (mouse monoclonal, clone CL0276) Fukuhara M1, Agnarsdóttir M1, Edqvist PH1, et al. SATB2 is expressed in Merkel cell carcinoma. Objective.

May 6, 2020 For example, SATB2 overexpression increased cell proliferation, stem cell-like gene expression and tumor growth in osteosarcoma (6); and

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. 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 All osteosarcomas were positive for SATB2 in both single cells and multinucleated cells with variable expression for CD68 and MITF. Only 1 out of 5 cases was positive (more than 50% of cells) for P63. Conclusions: Results suggest that SATB2 expression may present in significant numbers of GCTBs.

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.

2020-11-04 · SATB2 is an immunohistochemical marker for osteoblast differentiation. Our aim was to investigate SATB2 expression in oral osteosarcoma and other bone producing oral tumors/reactive lesions to evaluate its usefulness as a diagnostic marker. 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. Thus, our findings reveal a role for SATB2 in the regulation of p73 stability and function.

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 …. SATB2 is commonly expressed in osteosarcomas.

Thus, our findings reveal a role for SATB2 in the regulation of p73 stability and function. Moreover, we demonstrate that SATB2 is overexpressed in osteosarcoma (OS), while it is undetectable in other sarcomas, thereby suggesting that SATB2 may be a potential biomarker that can distinguish OS from other sarcomas.

She was subsequently lost to Recently, nuclear SATB2 expression has been shown to be useful to demonstrate osteoblastic differentiation in soft tissue and bone tumors, particularly when the distinction between hyalinized collagen and osteoid is challenging. 45 It is important to mention that the neoplastic cells in osteosarcoma may focally express keratins, EMA, SMA, and desmin in a subset of cases, complicating accurate Title:Dehydroandrographolide Inhibits Osteosarcoma Cell Growth and Metastasis by Targeting SATB2-mediated EMT VOLUME: 19 ISSUE: 14 Author(s):Xuefeng Liu, Yonggang Fan, Jing Xie, Li Zhang, Lihua Li* and Zhenyuan Wang* Interestingly, in 4 out of 5 tumors the mononuclear stromal component was strongly positive for SATB2. However, the giant cell component was negative. All osteosarcomas were positive for SATB2 in both single cells and multinucleated cells with variable expression for CD68 and MITF.
