It is now definitively established that a large part of the human genome is transcribed. However, only a scarce percentage of the transcriptome (about 1.2%) consists of RNAs that are translated into proteins, while the large majority of transcripts include a variety of RNA families with different dimensions and functions. Within this heterogeneous RNA world, a significant fraction consists of sequences with a length of more than 200 bases that form the so-called long non-coding RNA family. The functions of long non-coding RNAs range from the regulation of gene transcription to the changes in DNA topology and nucleosome modification and structural organization, to paraspeckle formation and cellular organelles maturation. This review is focused on the role of long non-coding RNAs as regulators of cyclin-dependent kinase inhibitors' (CDKIs) levels and activities. Cyclin-dependent kinases are enzymes necessary for the tuned progression of the cell division cycle. The control of their activity takes place at various levels. Among these, interaction with CDKIs is a vital mechanism. Through CDKI modulation, long non-coding RNAs implement control over cellular physiology and are associated with numerous pathologies. However, although there are robust data in the literature, the role of long non-coding RNAs in the modulation of CDKIs appears to still be underestimated, as well as their importance in cell proliferation control.

Abiotic challenges have a major impact on plant growth and development. Recent research has highlighted the role of long non-coding RNAs in response to these environmental stressors. Long non-coding RNAs are transcripts that are usually longer than 200 nucleotides with no potential for coding proteins.

The dengue virus (DENV) poses a significant threat to human health, accounting for approximately 400 million infections each year. Its genome features a circular structure that facilitates replication through long-range RNA-RNA interactions, utilizing cyclization sequences located in the untranslated regions (UTRs). To gain new insights into the organization of the DENV genome, we purified the 5' and 3' UTRs of DENV in vitro and examined their structural and binding properties using various biophysical techniques combined with computational methods.

In oxaliplatin-resistant gastric cancer (GC), multi-omics profiling combined with organoid libraries reveals altered metabolic pathways associated with chemoresistance. We identify a novel lactylation modification at K115 of Poly(RC)-binding protein 2 (PCBP2K115la), which confers functional oxaliplatin resistance. Mechanistic studies demonstrate that the long non-coding RNA BASP1-AS1 assembles a complex containing Unc-51 Like Autophagy Activating Kinase 1 (ULK1) and lactate dehydrogenase A (LDHA), thereby activating LDHA enzymatic activity to increase lactate production.

Gastric cancer (GC) is one of the leading causes of cancer-related deaths globally. Enhancer of zeste homolog 2 (EZH2), a methyl-transferase and master transcriptional regulator frequently overexpresses in a variety of malignancies. Long non-coding RNAs (lncRNAs) play a significant role in regulating gene expression and are intricately involved in the EZH2 oncogenic regulatory network.
