Studies using highly sensitive targeted RNA enrichment methods have shown that a large portion of the human transcriptome remains to be discovered and that most of the genome is transcribed in a complex, interleaved fashion characterized by a complex web of transcripts emanating from protein coding and noncoding loci. These results resonate with those from single-cell transcriptome profiling endeavors that reveal the existence of multiple novel, cell type-specific transcripts and clearly demonstrate that our understanding of the complexities of the human transcriptome is far from being complete. Here, we review the current status of the targeted RNA enrichment techniques, their application to the discovery of novel cell type-specific transcripts, and their impact on our understanding of the human genome and transcriptome.

Colorectal cancer (CRC) is a common malignant tumor characterized by a high degree of invasiveness, and since zinc-α2 glycoprotein (ZAG) has been implicated in the progression of several malignancies, this study was designed to investigate the role of ZAG in CRC. Its expression was assessed using the GEPIA database, and short hairpin RNA (shRNA) interference was conducted to create ZAG knockdown in CRC cell lines. We also conducted lipid synthesis, cell proliferation, apoptosis, and epithelial-mesenchymal transition (EMT) experiments to elucidate the effects of ZAG expression on CRC, as well as explored the potential underlying mechanistic pathways.

Unlabelled: Osimertinib has been demonstrated to be effective for improving the prognosis of patients with epidermal growth factor receptor mutation-positive lung cancer. However, osimertinib resistance inevitably emerges throughout the treatment course. This study explored the function and mechanism of long noncoding RNA LINC01278 in osimertinib-resistant NSCLC cells.

Unlabelled: Visceral leishmaniasis (VL), caused by , remains challenging to treat due to severe side effects and increasing drug resistance associated with current chemotherapies. Our study investigates the anti-leishmanial potential of from Uttarakhand, India, with extracts prepared from leaves and stems using ethanol and hexane. Advanced GC-MS analysis identified over 100 bioactive compounds, which were screened using molecular docking to assess their binding to LdHEL-67, a DDX3-DEAD box RNA helicase of donovani.

Despite these important advances, scRNA-seq is limited to measuring the transcriptome providing a partial view of cellular function. To address this limitation, multimodal scRNA-seq assays have emerged, allowing for the simultaneous measurement of RNA expression and protein.

Antiviral drugs are essential medications to save the lives of infected people. However, they are under constant threat to become ineffective as viruses evolve quickly. Studying the development of resistance is therefore paramount to understand the impact of mutations on pharmacological treatment and to make informed decisions.
