The role of filamins in mechanically stressed podocytes.

FASEB J 2021 May;35(5):e21560

Department of Anatomy and Cell Biology, University Medicine Greifswald, Greifswald, Germany.

Glomerular hypertension induces mechanical load to podocytes, often resulting in podocyte detachment and the development of glomerulosclerosis. Although it is well known that podocytes are mechanosensitive, the mechanosensors and mechanotransducers are still unknown. Since filamin A, an actin-binding protein, is already described to be a mechanosensor and mechanotransducer, we hypothesized that filamins could be important for the outside-in signaling as well as the actin cytoskeleton of podocytes under mechanical stress.

Transcriptional changes and preservation of bone mass in hibernating black bears.

Sci Rep 2021 Apr 15;11(1):8281. Epub 2021 Apr 15.

Institute of Arctic Biology, University of Alaska Fairbanks, 2140 Koyukuk Dr., Fairbanks, AK, 99775, USA.

Physical inactivity leads to losses of bone mass and strength in most mammalian species. In contrast, hibernating bears show no bone loss over the prolonged periods (4-6 months) of immobility during winter, which suggests that they have adaptive mechanisms to preserve bone mass. To identify transcriptional changes that underlie molecular mechanisms preventing disuse osteoporosis, we conducted a large-scale gene expression screening in the trabecular bone and bone marrow, comparing hibernating and summer active bears through sequencing of the transcriptome.

FCN3 functions as a tumor suppressor of lung adenocarcinoma through induction of endoplasmic reticulum stress.

Cell Death Dis 2021 Apr 15;12(4):407. Epub 2021 Apr 15.

Department of Life Science, Ewha Womans University, Seoul, Republic of Korea.

In this study, we report a novel function of FCN3 (Ficolin 3), a secreted lectin capable of activating the complement pathway, as a tumor suppressor of lung adenocarcinoma (LUAD). First, the expression of FCN3 was strongly down-regulated in cancer tissues compared to matched normal lung tissues, and down-regulation of FCN3 was shown to be significantly correlated with increased mortality among LUAD patients. Interestingly, while ectopic expression of FCN3 led to cell cycle arrest and apoptosis in A549 and H23 cells derived from LUAD, the secreted form of the protein had no effect on the cells. Read More

and Loss Induces an Immune Response in Zebrafish Livers Due to Viral Mimicry by Transposable Elements.

Front Immunol 2021 29;12:627926. Epub 2021 Mar 29.

Program in Biology, New York University Abu Dhabi, Abu Dhabi, United Arab Emirates.

Activation of transposable elements (TEs) can cause cellular damage. Cytoplasmic nucleic acid sensing pathways evolved to detect pathogens, but can also serve to cull cells with inappropriate TE activation as TEs can be viral mimetics. Epigenetic silencing of TEs is mediated in part by DNA methylation, but it is not clear if TE activation or the immune system contribute to the cellular damage caused by loss of DNA methylation.
