Objective: To develop a multiplex quantitative polymerase chain reaction (qPCR) assay based on the GenomeLab™ GeXP Genetic Analysis System (GeXP) for detection of long noncoding RNA in hepatocellular carcinoma (HCC).
Methods: From PubMed database articles published between 2011 and 2016, we selected 8 kinds of long noncoding RNAs (lncRNAs) related to HCC. Further, we examined 23 pairs of HCC and adjacent noncancerous tissues, using the optimized GeXP multiplex reverse transcription polymerase chain reaction (RT-PCR) assay.
Results: The expression level of lncRNA NEAT1, H19, MALAT1, HOTAIR, DANCR, UCA1, and BCAR4 were significantly decreased, compared with that in adjacent noncancerous tissues (all P <.05). The expression level of lncRNA GAS5 was statistically significantly increased (P <.05). For the quantitative polymerase chain reaction (qPCR) assay, 8 kinds of lncRNAs were detected as a result of the GeXP assay.
Conclusions: The GeXP-based multiplex RT-PCR assay may be used as an alternative method for assisting in the histopathological diagnosis of HCC in liver lesions.

Osteosarcoma (OS) is a commonly observed malignant tumor in orthopedics that has a very poor prognosis. The endosomal sorting complex required for transport (ESCRT) is important for the development and progression of cancer and may be a significant target for cancer therapy. First, we built a prognostic signature using 7 ESCRT-related genes (ERGs) to predict OS patient prognosis.

Background: The Japanese eel (Anguilla japonica) holds significant economic value in East Asia, but limitations in understanding its reproductive biology have hindered advancements in artificial breeding techniques. Previous research has primarily focused on conserved sex differentiation genes, offering limited insights into the broader molecular mechanisms driving gonadal development and sexual dimorphism. To address these limitations, this study aims to investigate key genes and pathways involved in gonadal development through a comprehensive transcriptomic analysis of male and female eel gonads.

Stomach adenocarcinoma (STAD) is a common malignancy with high heterogeneity and a lack of highly precise treatment options. We downloaded the multiomics data of STAD patients in The Cancer Genome Atlas (TCGA)-STAD cohort, which included mRNA, microRNA, long non-coding RNA, somatic mutation, and DNA methylation data, from the sxdyc website. We synthesized the multiomics data of patients with STAD using 10 clustering methods, construct a consensus machine learning-driven signature (CMLS)-related prognostic models by combining 10 machine learning methods, and evaluated the prognosis models using the C-index.
