Background and purpose:It was reported that nuclear factor of activated T cells (NFAT) is closely related with carcinomas. Esophageal squamous cell carcinoma (ESCC) is one of the most common carcinomas in China. The present study investigated the expression and clinical significance of NFAT isoforms in ESCC. Methods:The expression of NFAT isoforms and the differences in different pathological levels of ESCC were detected in 104 specimens of human ESCC tissues and normal esophageal tissues by immunohistochemistry. Results:This study found that the positive rates of NFAT1 (53.8%), NFAT2 (10.6%), NFAT3 (26.9%), NFAT4 (45.2%) expression were significantly higher in tumor tissues than in adjacent normal esophageal tissues (P<0.001), respectively. The positive rate of NFAT1 expression was significant-ly higher in drinkers (62.3%) than nondrinkers (37.1%, P=0.01), and also higher in patients with lymph node metastasis (68.4% vs 5.5%, P=0.002) and with late stage (58.7% vs 36.2%, P=0.02). Multivariate analysis showed that NFAT1 expression was correlated with lymph node metastasis. The positive rate of NFAT3 was significantly higher in patients with lymph node metastasis (39.4%) than in those without lymph node metastasis (19.7%, P=0.03). Conclusion:These results suggest that the overexpression of NFAT1 and NFAT3 is associated with lymph node metastasis in ESCC.

In Taiwan, high-risk patients have been identified and tested for preventing community spread of COVID-19. Most sample collection was performed in emergency departments (EDs). Traditional sample collection requires substantial personal protective equipment (PPE), healthcare professionals, sanitation workers, and isolation space. To solve this problem, we established a multifunctional sample collection station (MSCS) for COVID-19 testing in front of our ED. The station is composed of a thick and clear acrylic board (2 cm), which completely separates the patient and medical personnel. Three pairs of gloves (length, 45 cm) are attached and fixed on the outside wall of the MSCS. The gloves are used to conduct sampling of throat/nasal swabs, sputum, and blood from patients. The gap between the board and the building is only 0.2 cm (sealed with silicone sealant). ED personnel communicate with patients using a small two-way broadcast system. Medical waste is put in specific trashcans installed in the table outside the MSCS. With full physical protection, the personnel conducting the sampling procedure need to wear only their N95 mask and gloves. After we activated the station, our PPE, sampling time, and sanitization resources were considerably conserved during the 4-week observation period. The MSCS obviously saved time and PPE. It elevated the efficiency and capacity of the ED for handling potential community infections of COVID-19.

AIM: To investigate the role of ubiquitin-proteasome system ( UPS) in adipocyte differentiation. METHODS:Differentiation of 3T3-L1 preadipocytes into adipocytes was induced by treatment with insulin, 3-isobutyl-1-methylxanthine and dexamethasone.Western blot and immunoprecipitation were performed to detect the protein abundances and association, respectively.Oil red O staining was used to determine the intracellular lipid of 3T3-L1 adipocytes.The levels of mRNA were measured by reverse transcription polymerase chain reaction ( RT-PCR) .RESULTS:UPS inhibitor bortezomib (BZM) suppressed the differentiation of 3T3-L1 pre-adipocytes, evidenced by reduced intracellular content of triglyceride, and decreased mRNA expression of adipogenic marker proteins such as adiponectin and adipocyte protein 2.In contrast, administration of sildenafil (SDN), an activator of protein kinase G which was also found to activate UPS, promo-ted adipocyte differentiation.In addition, BZM treatment decreased the expression of heat shock protein 90 (HSP90) and peroxisome proliferator-activated receptor gamma ( PPARγ) in the soluble fraction and reduced association of HSP90 and PPARγ.Furthermore, HSP90-specific N-terminal inhibitor geldanamic mitigated SDN-induced increase in PPARγlevel and 3T3-L1 cell differentiation.CONCLUSION:UPS modulates HSP90-dependent PPARγstability, thus leading to pro-motion of adipocyte differentiation.
