Targeting LRH ‑1 in hepatoblastoma cell lines causes decreased proliferation.

Targeting LRH‑1 in hepatoblastoma cell lines causes decreased proliferation. Oncol Rep. 2018 Oct 15;: Authors: Jin J, Jin J, Woodfield SE, Patel RH, Jin NG, Shi Y, Liu B, Sun W, Chen X, Yu Y, Vasudevan SA Abstract Hepatoblastoma is the most common malignant liver tumor in children. Since it is often unresectable and exhibits drug resistance, the treatment of advanced hepatoblastoma is challenging. The orphan nuclear receptor liver receptor homolog‑1 (LRH‑1) serves prominent roles in malignancy; however, to the best of our knowledge, the role of LRH‑1 in hepatoblastoma remains unknown. In the present study, human hepatoblastoma cell lines were analyzed; the mRNA and protein expression levels of LRH‑1 were significantly higher in HepG2 and HuH6 cells compared with those in HepT1 cells and control THLE‑2 cells. Knockdown of LRH‑1 resulted in decreased HepG2 and HuH6 cell proliferation via downregulation of cyclin D1 (CCND1) and c‑Myc. Furthermore, treatment with an LRH‑1 antagonist (LRA) inhibited the proliferation and colony formation of cell lines in a dose‑dependent manner, and induced cell cycle arrest at G1 phase through inhibition of CCND1 expression. Finally, LRA treatment enhanced the cytotoxic effects of doxorubicin on hepatoblastoma cells. Collectively, these findings suggested that LRH‑1 may have an important role in the progression of hepatoblastoma and implicated LRA as a novel, potential therapeutic agent for the...

The histopathological assessment of pediatric liver tumors at presentation is critical to establish a diagnosis, guide treatment, and collect appropriate research samples. The purpose of this study was to evaluate complications associated with different approaches to liver biopsy for newly diagnosed hepatoblastoma.

CONCLUSIONS: At the moment there is no evidence from individual studies in children with osteosarcoma or hepatoblastoma treated with different platinum analogues and dosage schedules that underscores the use of amifostine as an otoprotective intervention as compared to no additional treatment. Since pooling of results was not possible and the evidence was of low certainty, no definitive conclusions can be made. Since we found only one RCT evaluating the use of sodium thiosulfate in children with localized hepatoblastoma treated with cisplatin, no definitive conclusions on benefits and harms can be drawn. It should be noted...

Conclusion: Taken together, lncRNA OIP5-AS1 acted as a ceRNA to drive proliferation, migration and invasion of HemECs through regulating miR-195-5p/NOB1 axis. Introduction Infant hemangioma (IH) is a benign neoplasm commonly seen in childhood, which is more common in premature infants and infants with low birth weight (Smith et al., 2017). There are three distinct clinical histological stages in IH: the early proliferative stage, when undeveloped blood vessels are rapidly growing; plateau stage and final regressive stage, with scattered capillaries and large drainage vessels (Csoma et al., 2017). IH is characterize...
