Abstract
The E3 SUMO ligase PIAS2 is expressed at high levels in differentiated papillary thyroid carcinomas but at low levels in anaplastic thyroid carcinomas (ATC), an undifferentiated cancer with high mortality. We show here that depletion of the PIAS2 beta isoform with a transcribed double-stranded RNA-directed RNA interference (PIAS2b-dsRNAi) specifically inhibits growth of ATC cell lines and patient primary cultures in vitro and of orthotopic patient-derived xenografts (oPDX) in vivo. Critically, PIAS2b-dsRNAi does not affect growth of normal or non-anaplastic thyroid tumor cultures (differentiated carcinoma, benign lesions) or cell lines. PIAS2b-dsRNAi also has an anti-cancer effect on other anaplastic human cancers (pancreas, lung, and gastric). Mechanistically, PIAS2b is required for proper mitotic spindle and centrosome assembly, and it is a dosage-sensitive protein in ATC. PIAS2b depletion promotes mitotic catastrophe at prophase. High-throughput proteomics reveals the proteasome (PSMC5) and spindle cytoskeleton (TUBB3) to be direct targets of PIAS2b SUMOylation at mitotic initiation. These results identify PIAS2b-dsRNAi as a promising therapy for ATC and other aggressive anaplastic carcinomas.

Appl Immunohistochem Mol Morphol 2022; 30:459-468. [PMID: 35603802 DOI: 10.1097/pai.0000000000001036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Accepted: 04/17/2022] [Indexed: 11/26/2022]
Abstract
High-grade neuroendocrine carcinoma (HGNEC) is subclassified into small cell carcinoma (SmCC) and large cell neuroendocrine carcinoma (LCNEC). Although both are clinically aggressive, the SmCC and LCNEC need to have different treatment strategies, and accurate pathologic diagnosis is challenging. We studied a large retrospective cohort (186 cases) of HGNEC of bladder and lung to investigate the abundance of cytokeratin (CK) 7 expression and staining pattern in SmCC and LCNEC. Overall, the pulmonary and urinary HGNEC exhibited several different CK7 staining patterns, including negative staining (n=28), dot-like staining (n=73), partial membranous staining (n=26), and complete membranous staining (n=60). Overall, 88.9% (44/49) of pulmonary SmCC and 88.0% (44/50) of urinary SmCC showed negative or dot-like patterns for CK7, while 90.8% (59/65) of pulmonary LCNEC and 72.7% (16/22) of urinary LCNEC showed partial or complete membranous patterns for CK7 (χ 2 =105.05, P <0.0001). The distinct staining patterns were also present in those mixed SmCC and LCNEC. In addition, the specimen types or fixation did not affect CK7 staining patterns. In conclusion, CK7 has a high differential value for SmCC and LCNEC and could help guide personalized treatment for patients.

Abstract
The current personalized oncology era has witnessed significant efforts to integrate clinical, pathological, and molecular classifications. The growing need for molecular biomarkers to feed personalized oncology, together with the unprecedented wealth of knowledge on the molecular basis of bladder cancer, has led to a novel approach to this disease, incorporating molecularly generated data in clinical practice for locally advanced or metastatic disease. Translational research allows a better understanding of the early events in the development of urothelial carcinoma in the urinary bladder. Thus, mutations in the KMT2D and KDM6A chromatin-modifying genes confer competitive advantages that drive cells to colonize larger regions of the urothelium. Additional mutations in TP53, PIK3CA, FGFR3, or RB1 genes then trigger the process of malignant transformation in the urothelium. In the current review, we provide an overview of what could be the expected transition from the morphology-based classification to a combined, molecularly enriched reporting of clinically meaningful parameters aiming to promote personalized oncology of urothelial carcinoma.

Abstract
OBJECTIVE To report the first case in the literature of a primary large-cell undifferentiated carcinoma (LCUC) of the ureter with a very aggressive behavior and dismal prognosis. CLINICAL PRESENTATION AND INTERVENTION A 60-year-old woman with a history of intermittent macroscopic hematuria and mild to moderate right flank pain was admitted to the Department of Urology. Tissue biopsies and cytological samples were taken. Pathologic examination was consistent with LCUC. CONCLUSION LCUC of the ureter is an aggressive tumor with a high proliferation index. Patients might be diagnosed at an advanced stage. LCUC must be considered in the differential diagnosis of urinary tract pathologies.

Abstract
Undifferentiated carcinoma of the esophagus is a rare histologic variant of esophageal carcinoma. Using criteria based on studies of undifferentiated carcinomas arising at other sites, we have collected 16 cases of resected esophageal undifferentiated carcinomas. Patients ranged in age from 39 to 84 years (mean, 65.5 years) and were predominantly male (94%). The tumors were characterized by an expansile growth pattern of neoplastic cells organized in solid sheets and without significant glandular, squamous, or neuroendocrine differentiation. The neoplastic cells had a syncytial-like appearance, little intervening stroma, and patchy tumor necrosis. In a subset of cases, the tumor cells adopted a sarcomatoid (n = 2), rhabdoid (n = 1), or minor component (<5%) of glandular morphology (n = 3). In 1 case, reactive osteoclast-like giant cells were found interspersed among the neoplastic cells. Lymphovascular invasion, perineural invasion, and lymph node metastases were identified in 88%, 56%, and 81% of cases, respectively. In 12 (75%) specimens, the background esophageal mucosa was notable for Barrett esophagus. Consistent with the epithelial nature of these neoplasms, cytokeratin positivity was identified in all cases. In addition, SALL4 expression was present in 8 (67%) of 12 cases. Follow-up information was available for 15 (94%) of 16 patients, all of whom were deceased. Survival after surgery ranged from 1 to 50 months (mean, 11.9 months). Before death, 67% patients had documented locoregional recurrence and/or distant organ metastases. In summary, esophageal undifferentiated carcinomas are aggressive neoplasms and associated with a high incidence of recurrence and/or metastases and a dismal prognosis.

Abstract
Morphological and functional preservation of urinary bladder epithelium-urothelium after extirpation from an organism enables physiological studies of that tissue and provides the basis for successful organ transplantations. The aim of this study was to determine the optimal temperature for maintaining urothelium in ex vivo conditions. Mouse urinary bladders were kept at the three temperatures usually used for maintaining tissue during transportation: at the temperature of melting ice (1°C), at room temperature (22-24°C), and at the body temperature of most mammals (37°C). Autolytic structural changes were followed with electron microscopy, while destruction of cytoskeleton and intercellular junctions was observed by immunolabeling. The first ultrastructural changes, swelling of mitochondria and necrosis of individual cells, became evident 30 min after extirpation if the tissue was kept at 1°C. After 60 and 120 min in ex vivo conditions, the most severe changes with increasing plasma membrane ruptures were detected at 1°C, while at room temperature only mild changes were detected. At 37°C, the extent of ultrastructural changes was between those of the other two experimental temperatures. Autolytic destruction of cytoskeleton and intercellular junctions was not observed before 2 h after extirpation. After 4 h, severe degradation of cytokeratin 20 and microtubules were found at 1°C and 37°C, while being almost undisturbed at room temperature. On the other hand, the reduction of desmoplakin and ZO-1 labeling was more evident at 37°C than at 1°C and room temperature. These findings provide evidence that room temperature is most appropriate for short ex vivo preservation of urothelial tissue.
