This paper reviews the strategic modifications incorporated into these vaccines to enhance mRNA stability and translation efficiency, such as the inclusion of nucleoside modifications and optimized mRNA design elements including the 5′ cap and poly(A) tail. We highlight emerging concerns regarding the wide systemic biodistribution of these mRNA vaccines leading to prolonged inflammatory responses and other safety concerns.

The stability of mRNA vaccines, their pervasive distribution, and the longevity of the encapsulated mRNA along with unlimited production of the damaging and potentially lethal spike (S) protein call for strategies to mitigate potential adverse effects.

A possible link between lung cancer and chronic obstructive pulmonary disease (COPD) has been suggested by recent studies.

To examine the association of COPD-related scores in lung cancer patients, we utilized the ssGSEA algorithm for single sample gene set enrichment analysis. The possible routes were examined through the utilization of Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis. Risk models were developed using Cox and least absolute shrinkage and selection operator (LASSO) regression analyses. Moreover, a GSEA was performed to investigate significant pathways among various risk groups.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Result&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;After identifying 17 genes that were differentially expressed and linked to COPD, we found that they met the criteria of having a false discovery rate &lt; 0.05 and an absolute log&lt;sub&gt;2&lt;/sub&gt; fold change &gt; 0.585. By utilizing the ssGSEA algorithm, it became possible to classify individuals with lung cancer into two distinct groups based on their COPD status. Consequently, a seven-gene risk model was developed specifically for these patients. The risk score was determined by applying the given formula: risk score = AC022784.1 × 0.0423737993775888 + CRISP3 × 0.0415322046890524 + MELTF × 0.0661848418476596 + MT2P1 × 0.111843227536117 + FAM83A-AS1 × 0.045295939710361 + ZNF506 × −0.309489953363417 + ITGA6 × 0.01813978449589. The risk model associated with COPD showed a notable connection with different immune cells found in the lung cancer sample, including macrophages of M0/M1/M2 types, hematopoietic stem cells, mast cells, NK T cells and regulatory T cells.

Sustained therapeutic success is therefore less likely in liver disorders requiring early intervention. We have previously developed a hybrid, dual virion approach, recombinant AAV (rAAV)/<i>piggyBac</i> transposon system capable of achieving stable gene transfer in proliferating hepatocytes at levels many fold above conventional AAV vectors. An alternative transposon system, <i>Sleeping Beauty</i>, has been widely used for <i>ex vivo</i> gene delivery; however liver-targeted delivery using a hybrid rAAV/<i>Sleeping Beauty</i> approach remains relatively unexplored.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>We investigated the capacity of a <i>Sleeping Beauty</i> (SB)-based dual rAAV virion approach to achieve stable and efficient gene transfer to the newborn murine liver using transposable therapeutic cassettes encoding coagulation factor IX or ornithine transcarbamylase (OTC).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>At equivalent doses, rAAV/SB100X transduced hepatocytes with high efficiency, achieving stable expression into adulthood. Compared with conventional AAV, the proportion of hepatocytes transduced, and factor IX and OTC activity levels, were both markedly increased. The proportion of hepatocytes stably transduced increased 4- to 8-fold from &lt;5%, and activity levels increased correspondingly, with markedly increased survival and stable urinary orotate levels in the OTC-deficient <i>Spf</i>^<i>ash</i> mouse following elimination of residual endogenous murine OTC.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>The present study demonstrates the first <i>in vivo</i> utility of a hybrid rAAV/SB100X transposon system to achieve stable long-term therapeutic gene expression following delivery to the highly proliferative newborn mouse liver.
