State‐of‐the‐Art Strategies for Circular RNA in Cancers: Opportunity and Challenge

MedComm, Volume 7, Issue 2, February 2026.
Overview of circular RNA in tumors. ABSTRACT Circular RNAs (circRNAs) are characterized by their covalently closed structure, remarkable stability, and precise spatiotemporal regulation, evolving from once‐overlooked transcriptional byproducts to pivotal molecular regulators.

Distinct 5′ UTR Requirements for Translation of the Bicistronic X/P mRNA Among Avian Orthobornaviruses

Microbiology and Immunology, Volume 70, Issue 2, Page 80-90, February 2026.
ABSTRACT Orthobornaviruses express X and the phosphoprotein (P) from a bicistronic X/P mRNA, and these proteins regulate polymerase activity. In mammalian orthobornaviruses, the 5′ untranslated region (5′ UTR) of the X/P mRNA controls the translational balance between X and P and thereby promotes efficient replication.

The Role of the Gut Microbiome in the Complex Network of Frailty Syndrome and Associated Comorbidities in Aging

Aging Cell, Volume 25, Issue 2, February 2026.
This study analyzed gut microbiota in older adults with and without Frailty Syndrome by 16S rRNA gene sequencing and metagenomics. Frailty was associated with altered microbial composition, metabolic functions, and increased antimicrobial resistance, whereas non‐frail individuals showed healthier profiles.

The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

Molecular Microbiology, Volume 125, Issue 2, Page 108-122, February 2026.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

Manipulation of the Unfolded Protein Response by Intracellular Bacterial Pathogens: Mechanisms of ER Hijacking and Therapeutic Implications

The FASEB Journal, Volume 40, Issue 2, 31 January 2026.
This review illustrates how intracellular bacterial pathogens—such as Brucella, Mycobacterium tuberculosis, and Legionella—secrete effector proteins that specifically target the IRE1α, PERK, and ATF6 branches of the unfolded protein response (UPR) to hijack ER stress signaling.

Lysophosphatidic Acid Synergizes With 1,25‐Dihydroxyvitamin D to Promote Fibroblast Growth Factor‐23 Synthesis via MAPK Signaling and Induction of the IL12A Gene

The FASEB Journal, Volume 40, Issue 1, 15 January 2026.
Ay et al. investigated the cellular mechanisms behind the role of lysophosphatidic acid (LPA) in FGF23 production. They revealed that LPA cooperates with 1,25‐dihydroxyvitamin D (1,25D), that is, the bioactive form of vitamin D known to stimulate FGF23 synthesis. This synergy entails MAPK signaling and the induction of the gene encoding the interleukin‐

Current status of ribosome inactivating proteins.

Indian journal of biochemistry & biophysics, 2000
Ribosome inactivating proteins (RIPs) are a group of naturally occurring plant proteins with a RNA-N-glycosidases activity which depurinate rRNA at a specific universally conserved position (i.e. cleavage of N-glycosidic bond of a specific adenine of 28S rRNA).
