AI Article Synopsis
- Bladder cancer is a common type of cancer among men, influenced by genetic and environmental factors.
- This study focuses on the long non-coding RNA HULC, exploring its role in bladder cancer and how it affects tumor behavior.
- Results indicated that higher levels of HULC in patients were linked to more advanced cancer stages, increased cell growth, and reduced apoptosis, suggesting it plays a critical role in bladder cancer progression.
Article Abstract
Background: Bladder cancer is the fourth most common malignancy among men urinary system and it is a complex disease caused by genetic and environmental factors.
Objective: This study aimed to evaluate the effects of hepatocellular carcinoma up-regulated long non-coding RNA (lncRNA HULC) on bladder cancer and to reveal the potential mechanisms.
Methods: The expression level of HULC in 276 bladder cancer patients was detected. The association of HULC level with patient recurrence was performed by Kaplan-Meier and log-rank test. Moreover, T24 and RT4 cells were transfected with HULC and ZIC2 targeted siRNAs, HULC expressing vector and corresponding controls. Subsequently, cell viability, apoptosis and tumorigenesis were examined.
Results: The expression level of HULC was increased in bladder cancer tissues. High expression of HULC was correlated with advanced clinical stage and lower recurrence-free rate. HULC was remarkably promoted cell viability but inhibited apoptosis, meanwhile conspicuously increased the expression of Cyclin A/D1/E and Bcl-2. Xenograft tumor model showed that HULC promoted tumor weights in vivo.
Conclusions: LncRNA HULC promoted bladder cancer cells proliferation and inhibited apoptosis.

Expression Patterns of DLL3 Across Neuroendocrine and Non-Neuroendocrine Neoplasms Reveal Broad Opportunities for Therapeutic Targeting.

Neuroendocrine neoplasms (NENs) encompass a diverse set of malignancies with limited precision therapy options. Recently, therapies targeting DLL3 have shown clinical efficacy in aggressive NENs, including small cell lung cancers and neuroendocrine prostate cancers. Given the continued development and expansion of DLL3-targeted therapies, we sought to characterize the expression of DLL3 and identify its clinical and molecular correlates across diverse neuroendocrine and non-neuroendocrine cancers.

Splice-switching oligonucleotides (SSOs) can restore protein functionality in pathologies and are promising tools for manipulating the RNA-splicing machinery. Delivery vectors can considerably improve SSO functionality in vivo and allow dose reduction, thereby addressing the challenges of RNA-targeted therapeutics. Here, we report a biocompatible SSO nanocarrier, based on redox-responsive disulfide cross-linked low-molecular-weight linear polyethylenimine (cLPEI), for overcoming multiple biological barriers from subcellular compartments to en-route serum stability and finally in vivo delivery challenges.
