Abstract

Transmembrane protein 100 (TMEM100) is a crucial factor in the development and maintenance of the vascular system. The protein is involved in several processes such as angiogenesis, vascular morphogenesis, and integrity. Furthermore, TMEM100 is a downstream target of the BMP9/10 and BMPR2/ALK1 signaling pathways, which are key regulators of vascular development. Our recent studies have shown that TMEM100 is a lung endothelium enriched gene and plays a significant role in lung vascular repair and regeneration. The importance of TMEM100 in endothelial cells’ regeneration was demonstrated when Tmem100 was specifically deleted in endothelial cells, causing an impairment in their regenerative ability. However, the role of TMEM100 in various conditions and diseases is still largely unknown, making it an interesting area of research. This review summarizes the current knowledge of TMEM100, including its expression pattern, function, molecular signaling, and clinical implications, which could be valuable in the development of novel therapies for the treatment of cardiovascular and pulmonary diseases.

Figure 2 Role of TMEM100. TMEM100 is a two transmembrane protein located in the plasma membrane and endoplasmic reticulum membrane. TMEM100 is a BMP9/10-BMPR2/ALK1-pSMAD1/5/8 signaling downstream target. Various factors such as VEGF, PEG11/RGL1, GATA5, Calcium signaling and ATF6α upregulate TMEM100 expression. Inflammatory cytokines such as TNF-α, miR421/miR106, and HDAC6 suppress TMEM100 expression. TMEM100 has been demonstrated to positively regulate NOTCH, MFAP4, and E2F1 signaling, and inhibit JNK/ERK, β-catenin, TGF-β signaling. Our unpublished data showed that hypoxia and inflammatory injury reduce TMEM100 expression in the lung ECs, whereas VEGF upregulates TMEM100 expression. (indicated by dotted lines).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
