Previous investigations on the expression and function of special AT-rich sequence binding protein 2 (Satb2) are largely limited to the cerebral cortex. Here, we explore the expression of Satb2 thoroughly by immunohistochemistry in the adult mouse central nervous system (CNS). Besides the cerebral cortex, we found that Satb2 is specifically expressed in the bed nucleus of the stria terminalis, horizontal limb of the diagonal band, lateral hypothalamic area, arcuate nucleus, hypothalamic paraventricular nucleus, ventral tegmental nucleus, laterodorsal tegmental nucleus, dorsal raphe nucleus, rostral periolivary region, and parabrachial nucleus. Double immunostaining showed that Satb2 is exclusively expressed in the excitatory neurons of neocortex. In addition, Satb2 is specifically expressed in A12 group of hypothalamic dopaminergic neurons and in serotonergic neurons in the dorsal part of the dorsal raphe nucleus. Our results present a comprehensive overview of Satb2 expression in the adult brain and provide insights for studying the role of Satb2 in the mature CNS.

Fibro-osseous tumors of the craniofacial bones are a heterogeneous group of lesions comprising cemento-osseous dysplasia (COD), cemento-ossifying fibroma (COF), juvenile trabecular ossifying fibroma (JTOF), psammomatoid ossifying fibroma (PsOF), fibrous dysplasia (FD), and low-grade osteosarcoma (LGOS) with overlapping clinicopathological features. However, their clinical behavior and treatment differ significantly, underlining the need for accurate diagnosis. Molecular diagnostic markers exist for subsets of these tumors, including GNAS mutations in FD, SATB2 fusions in PsOF, mutations involving the RAS-MAPK signaling pathway in COD, and MDM2 amplification in LGOS.

Purpose: This pilot study evaluated and compared histomorphometric and immunohistochemical characteristics of peri-implant bone tissue after implant site preparation using piezoelectric tips versus conventional drills.
Material And Methods: Six patients with bilateral partial edentulism underwent a splitmouth protocol. Twelve alveolar ridges were randomized into six control implant sites prepared using conventional drills (Drill Group); and six test implant sites prepared using piezoelectric implant inserts (Piezo Group).

Merkel cell carcinoma (MCC) is an uncommon aggressive neoplasm, usually arising in sun-exposed skin of the head and neck. By immunohistochemistry, KRT20 and MCPyV positivity are found in about 90% and 80% of MCCs, respectively. Noteworthy, viral status in lip/oral cavity MCCs is poorly known.

Context: Hepatocyte nuclear factor (HNF)-4α is a marker of gastrointestinal tumor differentiation; however, its expression in endocervical tumors remains unclear.
Objective: We aimed to assess the utility of HNF4α expression as a marker for endocervical adenocarcinomas (ECAs) and adenocarcinoma in situs (AISs), and to establish a minimal panel for distinguishing them from nonneoplastic endocervical glandular lesions and metastases.
Design: HNF4α expression was analyzed immunohistochemically (positive, H-score ≥10) in 323 tissue samples: 57 endocervical neoplasms including 35 glandular neoplasms and 22 squamous neoplasms, 144 nonneoplastic endocervical lesions, and 122 tumors from other organs.

Background: Special AT-rich binding protein-2 (SATB2) is a nuclear matrix associated protein regulating gene expression which is normally expressed in colonic tissue. Loss of SATB2 expression in colorectal cancer (CRC) has negative implications for prognosis and has been associated with chemotherapy resistance. Furthermore, recent evidence suggests SATB2 may influence immune checkpoint (IC) expression.
