Glioma is a malignant primary brain tumor that occurs in the central nervous system and has threatened the well-being of millions of patients. It is well acknowledged that long non-coding RNA (lncRNA) SNHG3 participates in the regulation of proliferation, inflation, differentiation, and metastasis in many cancers. However, the regulatory effect of SNHG3 on glioma progression is still controversial. The expression of SNHG3 and HDGF was upregulated, whereas miR-384 was downregulated in glioma tissues, compared with the normal tissues. Interestingly, high SNHG3 contributed to low survival rate while low SNHG3 showed the opposite result. Moreover, SNHG3 or HDGF knockdown significantly suppressed proliferation, migration, and invasion and induced apoptosis in glioma. Meanwhile, restoration of HDGF abrogated the inhibition of SNHG3 silencing on glioma cell progression. Besides, miR-384 inhibitor attenuated SNHG3 silencing induced inhibition on HDGF mRNA and protein expression in A172 and SHG44 cells. LncRNA SNHG3 promotes cell proliferation, migration, and invasion in glioma by enhancing HDGF expression via miR-384 sponging, representing the promising targets for the development of novel therapeutic strategies.

Background/aims: Studies have shown the significance of long non-coding RNAs (lncRNAs) in the development of malignant tumors, including cholangiocarcinoma (CCA). However, the molecular mechanisms through which the lncRNA SNHG3 contributes to CCA development remain unknown. Therefore, the purpose of this work was to investigate SNHG3's role and possible processes in CCA.

Article Synopsis
- - LncRNAs play a significant role in the risk and severity of metabolic dysfunction-associated fatty liver disease (MASLD), though their exact functions are still unclear.
- - In a study involving diet-induced obesity in mice, a specific lncRNA was found to be significantly decreased, and its overexpression led to increased fat accumulation in liver cells.
- - The research proposed a new signaling pathway involving the lncRNA, SND1 protein, and PPARγ, highlighting the importance of lncRNA in epigenetic modifications related to MASLD pathology.

Introduction: Hepatocellular Carcinoma (HCC) is a common malignant tumor worldwide. Long Non-Coding RNA (lncRNA) has gained attention in tumor biology, and this study aims to investigate the role of lncRNA SNHG3 in HCC, specifically in the self-renewal and maintenance of liver cancer stem cells.
Methods: The expression of lncRNA SNHG3 was analyzed in HCC and adjacent normal tissue using the TCGA database.

Article Synopsis
- Endoplasmic reticulum stress (ERS) and cuproptosis impact hepatocellular carcinoma (HCC) prognosis, leading to the study of lncRNAs linked to these processes for better predictability.
- The research utilized data from the TCGA database to identify a prognostic signature comprising specific lncRNAs (NRAV, SNHG3, LINC00839, and AC004687.1) through various analytical methods like Cox regression and LASSO.
- Findings indicated high-risk patients generally faced worse outcomes, while low-risk groups showed improved immune status and disease response, establishing the identified lncRNA signature as a valuable tool for predicting HCC prognosis and treatment effectiveness.
