AI Article Synopsis
- Several features distinguish aged cells from young cells due to changes in gene expression driven by aging.
- The study identified the lncRNA FLJ46906 as consistently increased in expression with aging in skin fibroblasts, both in living organisms and in lab settings.
- It was found that FLJ46906 regulates several genes associated with aging through its direct interaction with the transcription factors NF-κB and AP-1, suggesting it plays a significant role in the aging process.
Article Abstract
Several features differentiate aged cells from young cells, many of which are due to changes in gene expression during the aging process. The mechanisms of altered gene expression in aging cells remain incompletely understood, and we hypothesized that long non-coding (lnc) RNAs mediate at least some of these changes. We screened for alterations in lncRNA expression with aging in skin fibroblasts and identified the lncRNA FLJ46906 to be consistently upregulated with aging in-vivo and in-vitro. The function of this lncRNA has not been known. Here we show that FLJ46906 regulates several aging-associated genes, including , , , and We suggest that these effects are mediated through NF-κB and AP-1, because these aging-associated genes are regulated by NF-κB and AP-1, and because we found that FLJ46906 directly binds to these two transcription factors. This data supports a role of the lncRNA FLJ46906 in the aging process.

The marine ecosystem is characterized by a rich diversity of bacterial hosts and their phages. The propagation of phages is primarily limited by their ability to adsorb to host cells and is further challenged by various bacterial defense mechanisms. To fully realize the potential of phage therapy in aquaculture, a comprehensive understanding of phage-host interactions and their regulation is essential.

Unlabelled: Lipopolysaccharide (LPS), a gut-derived endotoxin, is a recognized risk factor for both Non-alcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD). Rocaglamide-A (Roc-A), a natural compound derived from the genus Aglaia, is known for its pharmacological and immunosuppressive effects on various cell types. Although our recent investigations have unveiled Roc-A's anti-adipogenic role in adipocytes, its mechanism in hepatic inflammation remains elusive.

In-stent restenosis (ISR) following interventional therapy is a fatal clinical complication. Current evidence indicates that neointimal hyperplasia driven by uncontrolled proliferation of vascular smooth muscle cells (VSMC) is a major cause of restenosis. This implies that inhibiting VSMC proliferation may be an attractive approach for preventing in-stent restenosis.
