A 122 nt uridine-rich sequence (URE) in the Na(+)/glucose cotransporter (SGLT1) mRNA 3'-untranslated region is critical for cAMP-dependent message stabilization. Its function was investigated in LLC-PK(1) cells stably expressing beta-globin reporter transcripts. Insertion of the SGLT1 URE downstream from an unrelated destabilizing sequence, the c-fos ARE, evoked cAMP-dependent message stabilization. Stabilization was blocked by a substitution mutation within the SLGT1 URE. These observations indicate that the SGLT1 URE is sufficient to transmit cAMP-dependent, cis-dominant mRNA stabilization in the presence of appropriate trans-acting factors and appears to function independently of the nature of the destabilizing domain.

LncRNA TCL6 regulates miR-876-5p/MYL2 axis to suppress breast cancer progression.

We explored the influence of the TCL6/miR-876-5p axis on breast cancer cell proliferation and migration. Using The Cancer Genome Atlas (TCGA) database, we evaluated the expression of TCL6 in breast cancer patients and studied its effects on cell proliferation, migration, and the cell cycle in vitro. The regulatory effect of miR-876-5p on myosin light chain-2 (MYL2) 3' untranslated regions (3'UTR) was analyzed through luciferase reporter assays, and rescue experiments confirmed TCL6-driven upregulation of MYL2 via a competitive RNA binding mechanism.

Lipid nanoparticles (LNPs) are often liver tropic, presenting challenges for LNP-delivered mRNA therapeutics intended for other tissues, as off-target expression in the liver may increase side effects and modulate immune responses. To avoid off-target expression in the liver, miR-122 binding sites have been used by others in viral and non-viral therapeutics. Here, we use a luciferase reporter system to compare different copy numbers and insertion locations of miR-122 binding sequences to restrict liver expression.

Laryngeal squamous cell cancer (LSCC) is one of the most common head and neck cancers in which genetic factors play an important role in its occurrence. This study investigated the association of and gene polymorphisms with the risk of LSCC. polymorphisms including rs712, rs61764370, rs8720, and rs9266, as well as NRAS rs14804, were compared in the patient group (n=120) and the control group (n=100).
