LncRNAs in necroptosis: Deciphering their role in cancer pathogenesis and therapy

Necroptosis, a controlled type of cell death that is different from apoptosis, has become a key figure in the aetiology of cancer and offers a possible target for treatment. A growing number of biological activities, including necroptosis, have been linked to long noncoding RNAs (lncRNAs), a varied family of RNA molecules with limited capacity to code for proteins. The complex interactions between LncRNAs and important molecular effectors of necroptosis, including mixed lineage kinase domain-like pseudokinase (MLKL) and receptor-interacting protein kinase 3 (RIPK3), will be investigated. We will explore the many methods that LncRNAs use to affect necroptosis, including protein-protein interactions, transcriptional control, and post-transcriptional modification. Additionally, the deregulation of certain LncRNAs in different forms of cancer will be discussed, highlighting their dual function in influencing necroptotic processes as tumour suppressors and oncogenes. The goal of this study is to thoroughly examine the complex role that LncRNAs play in controlling necroptotic pathways and how that regulation affects the onset and spread of cancer. In the necroptosis for cancer treatment, this review will also provide insight into the possible therapeutic uses of targeting LncRNAs. Techniques utilising LncRNA-based medicines show promise in controlling necroptotic pathways to prevent cancer from spreading and improve the effectiveness of treatment.

Cost effectiveness of proton pump inhibitors in gastro-oesophageal reflux disease without oesophagitis: comparison of on-demand esomeprazole with conventional omeprazole strategies

OBJECTIVES

To evaluate the cost effectiveness of on-demand treatment with esomeprazole 20mg compared with two alternative omeprazole treatment strategies for the long-term management of patients with gastro-oesophageal reflux disease (GORD) without oesophagitis.

DESIGN

A simple Markov model was designed to compare the cost effectiveness of on-demand esomeprazole 20mg therapy for 6 months with a strategy consisting of intermittent 4-week acute treatment courses of omeprazole 20mg once daily or a strategy consisting of continuous omeprazole treatment (20mg once daily) following acute treatment of first relapse while on no drug treatment (a commonly used conventional care strategy). Relapse probabilities were based on pooled results from two 6-month placebo-controlled clinical studies of on-demand esomeprazole 20mg treatment in patients with GORD without oesophagitis and on results from a GORD study with a 6-month untreated follow-up. The expected number of relapses per patient was used as the effectiveness measure. SETTING AND PERSPECTIVE: Patient management assumptions were based on a UK physician survey. The cost-effectiveness analysis considered UK direct medical costs from the perspective of the National Health Service.

RESULTS

The pooled analysis showed that after 6 months treatment, 90% of patients could control symptoms effectively with on-demand esomeprazole 20mg. The expected number of relapses per patient was estimated at 0.10 for on-demand esomeprazole, 0.57 to 1.12 for intermittent omeprazole and 0.47 to 0.75 for conventional omeprazole treatment. The esomeprazole strategy incurred considerably lower direct medical costs (16 to 61%) than either omeprazole strategy.

CONCLUSION

On-demand treatment with esomeprazole 20mg is cost effective compared with two alternative omeprazole treatment strategies in patients with GORD without oesophagitis.
