Characterization of Somatostatin Receptor 2 Gene Expression and Immune Landscape in Sinonasal Malignancies.

Olfactory neuroblastoma (ONB), sinonasal undifferentiated carcinoma (SNUC), and sinonasal neuroendocrine carcinoma (SNEC) are rare malignancies arising from the sinonasal tract with limited therapeutic options. The expression of the somatostatin receptor 2 gene (), which is expressed in other neuroendocrine neoplasms and is therapeutically actionable, has been reported in these tumors. Here, we analyzed gene expression and its associations with genomic features, established biomarkers predicting of immune response, and the tumor immune microenvironment in a cohort of ONB, SNUC, and SNEC tumor samples (26, 13, and 8 samples, respectively) from a real-world database.

Binding properties of olfactory proteins to host volatiles, free fatty acids and cuticular hydrocarbons in the termite Reticulitermes aculabialis.

As eusocial insects prevalent in tropical and subtropical regions, termites are characterized by highly organized behaviors and exceptional adaptability, rooted in caste differentiation and chemical communication. These traits make them excellent models for studying insect social structures and ecological interactions. Investigating how termites use chemical signals to perceive and respond to their environment provides insights into their coordination and adaptation within complex ecosystems.

Risk stratification of ThyroSeq results in indeterminate thyroid lesions: A single-institution experience of clinicopathologic correlation with cytologic findings.

Background: ThyroSeq offers the opportunity to stratify the risk of malignancy (ROM) in the characterization of indeterminate thyroid nodules, especially those categorized as atypia of undetermined significance (AUS). However, whether ThyroSeq interpretations correlate with cytologic features, management, and surgical outcome remains unclear.

Methods: Thyroid fine-needle aspiration specimens categorized as AUS and follicular neoplasm (FN) from 2017 to 2021 were identified from a cytology database search.

Programmed death-ligand 1 expression in patients with primary or secondary myelofibrosis.

Background: It has been described in mice models that myeloproliferative neoplasm (MPN) with JAK2-V617F mutation has an increased expression of programmed death-ligand 1 (PD-L1) in megakaryocytes leading to cancer immune evasion by inhibiting the T-lymphocytes.

Aims: To quantify and compare the PD-L1 expression on bone marrow (BM) of patients with MPN JAK2 positive, negative, and normal controls.

Methods: We collected BM of patients with MPN JAK2 positive, negative and normal controls from 1990 to 2019.
