Introduction

Binds the poly(A) tail of mRNA. May be involved in cytoplasmic regulatory processes of mRNA metabolism. Can probably bind to cytoplasmic RNA sequences other than poly(A) in vivo (By similarity).

AbstractA 70‐year‐old man undergoing treatment for immunoglobulin G4‐related disease developed a liver mass on computed tomography during routine imaging examination. The tumor was located in the hepatic S1/4 region, was 38 mm in size, and showed arterial enhancement on dynamic contrast‐enhanced computed tomography. We performed a liver biopsy and diagnosed moderately differentiated hepatocellular carcinoma. The patient underwent proton beam therapy. The tumor remained unchanged but enlarged after 4 years. The patient was diagnosed with hepatocellular carcinoma recurrence and received hepatic arterial chemoembolization. However, 1 year later, the patient developed jaundice, and the liver tumor grew in size. Unfortunately, the patient passed away. Autopsy revealed that the tumor consisted of spindle‐shaped cells exhibiting nuclear atypia and a fission pattern and tested positive for α‐smooth muscle actin and vimentin. No hepatocellular carcinoma components were observed, and the patient was pathologically diagnosed with hepatic leiomyosarcoma. Next‐generation sequencing revealed somatic mutations in CACNA2D4, CTNNB1, DOCK5, IPO8, MTMR1, PABPC5, SEMA6D, and ZFP36L1. Based on the genetic mutation, sarcomatoid hepatocarcinoma was the most likely pathogenesis in this case. This mutation is indicative of the transition from sarcomatoid hepatocarcinoma to hepatic leiomyosarcoma.

Although mutations of genes are crucial events in tumorigenesis and development, the association between gene mutations and lung cancer metastasis is still largely unknown. The goal of this study is to identify driver and novel genes associated with non-small cell lung cancer (NSCLC) metastasis. Candidate genes were identified using a novel comprehensive analysis, which was based on bioinformatics technology and meta-analysis. Firstly, EGFR, KRAS, ALK, TP53, BRAF and PIK3CA were identified as candidate driver genes. Further meta-analysis identified that EGFR (Pooled OR 1.33, 95% CI 1.19, 1.50; P < .001) and ALK (Pooled OR 1.52, 95% CI 1.22, 1.89; P < .001) mutations were associated with distant metastasis of NSCLC. Besides, ALK (Pooled OR 2.40, 95% CI 1.71, 3.38; P < .001) mutation was associated with lymph node metastasis of NSCLC. In addition, thirteen novel gene mutations were identified to be correlated with NSCLC metastasis, including SMARCA1, GGCX, KIF24, LRRK1, LILRA4, OR2T10, EDNRB, NR1H4, ARID4A, PRKCI, PABPC5, ACAN and TLN1. Furthermore, elevated mRNA expression level of SMARCA1 and EDNRB was associated with poor overall survival in lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC), respectively. Additionally, pathway and protein-protein interactions network analyses found the two genes were correlated with epithelial-mesenchymal transition process. In conclusion, mutations of EGFR and ALK were significantly correlated with NSCLC metastasis. In addition, thirteen novel genes were identified to be associated with NSCLC metastasis, especially SMARCA1 in LUAD and EDNRB in LUSC.

Glioma is the most common primary malignancy in the brain, and vasculogenic mimicry (VM) is one of the blood supply methods. Here we investigated the possibility that lncRNAs regulate the stability of transcription factors through the SMD pathway, which affects proliferation, migration, invasion, and the ability to form VMs in glioma. Expression of PABPC5, HCG15, and ZNF331 was detected by real-time qPCR or western blot in glioma. Cell Counting Kit-8, Transwell assays, and in vitro VM tube formation were used to investigate PABPC5, HCG15, and ZNF331 function in cell proliferation, migration, invasion, and VM, respectively. ChIP assays were used to ascertain the interaction betweenZNF331 and LAMC2 or PABPC5. PABPC5 and HCG15 were highly expressed in glioma cells. ZNF331 was lowly expressed. PABPC5 bound HCG15 to increase its stability. Knockdown HCG15 reduced the degradation of ZNF331 mRNA by the SMD pathway. ZNF331 inhibited transcription through binding to the promoter region of LAMC2 and PABPC5 and inhibited the ability to form VMs in glioma cells. The PABPC5/HCG15/ZNF331 feedback loop plays an important role in regulating VM formation in glioma and provides new targets for glioma treatment.
