Tubulin Regulates Plasma Membrane Ca 2+-ATPase Activity in a Lipid Environment-dependent Manner. Cell Biochem Biophys 2024; 82:319-328. [PMID: 38133791 DOI: 10.1007/s12013-023-01206-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 11/30/2023] [Indexed: 12/23/2023]
Abstract
Ca2+ plays a crucial role in cell signaling, cytosolic Ca2+ can change up to 10,000-fold in concentration due to the action of Ca2+-ATPases, including PMCA, SERCA and SCR. The regulation and balance of these enzymes are essential to maintain cytosolic Ca2+ homeostasis. Our laboratory has discovered a novel PMCA regulatory system, involving acetylated tubulin alone or in combination with membrane lipids. This regulation controls cytosolic Ca2+ levels and influences cellular properties such as erythrocyte rheology. This review summarizes the findings on the regulatory mechanism of PMCA activity by acetylated tubulin in combination with lipids. The combination of tubulin cytoskeleton and membrane lipids suggests a novel regulatory system for PMCA, which consequently affects cytosolic Ca2+ content, depending on cytoskeletal and plasma membrane dynamics. Understanding the interaction between acetylated tubulin, lipids and PMCA activity provides new insights into Ca2+ signaling and cell function. Further research may shed light on potential therapeutic targets for diseases related to Ca2+ dysregulation. This discovery contributes to a broader understanding of cellular processes and offers opportunities to develop innovative approaches to treat Ca2+-related disorders. By elucidating the complex regulatory mechanisms of Ca2+ homeostasis, we advance our understanding of cell biology and its implications for human health.

Prevention of tubulin/aldose reductase association delays the development of pathological complications in diabetic rats. J Physiol Biochem 2021; 77:565-576.

Abstract
In recent studies, we found that compounds derived from phenolic acids (CAFs) prevent the formation of the tubulin/aldose reductase complex and, consequently, may decrease the occurrence or delay the development of secondary pathologies associated with aldose reductase activation in diabetes mellitus. To verify this hypothesis, we determined the effect of CAFs on Na+,K+-ATPase tubulin-dependent activity in COS cells, ex vivo cataract formation in rat lenses and finally, to evaluate the antidiabetic effect of CAFs, diabetes mellitus was induced in Wistar rats, they were treated with different CAFs and four parameters were determinates: cataract formation, erythrocyte deformability, nephropathy and blood pressure. After confirming that CAFs are able to prevent the association between aldose reductase and tubulin, we found that treatment of diabetic rats with these compounds decreased membrane-associated acetylated tubulin, increased NKA activity, and thus reversed the development of four AR-activated complications of diabetes mellitus determined in this work. Based on these results, the existence of a new physiological mechanism is proposed, in which tubulin is a key regulator of aldose reductase activity. This mechanism can explain the incorrect functioning of aldose reductase and Na+,K+-ATPase, two key enzymes in the pathogenesis of diabetes mellitus. Moreover, we found that such alterations can be prevented by CAFs, which are able to dissociate tubulin/aldose reductase complex.

Inhibition of flippase-like activity by tubulin regulates phosphatidylserine exposure in erythrocytes from hypertensive and diabetic patients. J Biochem 2021; 169:731-745.

Abstract
Plasma membrane tubulin is an endogenous regulator of P-ATPases and the unusual accumulation of tubulin in the erythrocyte membrane results in a partial inhibition of some their activities, causing hemorheological disorders like reduced cell deformability and osmotic resistance. These disorders are of particular interest in hypertension and diabetes, where the abnormal increase in membrane tubulin may be related to the disease development. Phosphatidylserine is more exposed on the membrane of diabetic erythrocytes than in healthy cells. In most cells, phosphatidylserine is transported from the exoplasmic to the cytoplasmic leaflet of the membrane by lipid flippases. Here we report that phosphatidylserine is more exposed in erythrocytes from both hypertensive and diabetic patients than in healthy erythrocytes, which could be attributed to the inhibition of flippase activity by tubulin. This is supported by: (i)- the translocation rate of a fluorescent phosphatidylserine analog in hypertensive and diabetic erythrocytes was slower than in healthy cells, (ii)- the pharmacological variation of membrane tubulin in erythrocytes and K562 cells was linked to changes in phosphatidylserine translocation, (iii)- the P-ATPase-dependent phosphatidylserine translocation in inside-out vesicles from human erythrocytes was inhibited by tubulin. These results suggest that tubulin regulates flippase activity and hence the membrane phospholipid asymmetry.

Abstract
Nitrotyrosine, a structural analogue of tyrosine, is present in cells in pathological conditions and is incorporated into tubulin to form tubulin tyrosine nitration, which disrupts the normal function of microtubules. There is limited research on the functional aspects of tubulin tyrosine nitration in different types of tumor. In the present study, the effect of tubulin tyrosine nitration and tubulin tyrosine ligase like 12 (TTLL12) on the proliferation of SCC-25 cells was investigated. TTLL12-overexpressing cell lines were constructed and used to assess the effect of tubulin tyrosine nitration and TTLL12 on the proliferation of SCC-25 cells via western blotting, immunofluorescent and MTT assays. An TTLL12-stably overexpressing SCC-25 cell line and the enzyme-linked immunosorbent assay were used to establish a novel experiment in vitro for screening anticancer drugs targeting tubulin tyrosine nitration by assessing its sensitivity, specificity and repeatability, and using it to find an effective drug. The results demonstrated that the proliferative rate of the control cells was notably inhibited in the presence of nitrotyrosine compared with that of TTLL12-overexpressing cells. The results of the MTT assay revealed that the proliferation of TTLL12-silenced cells was significantly inhibited compared with that of the control group. The sensitivity, specificity and repeatability of the experiment were positive. It was found that nocodazole could have better anticancer effect than paclitaxel. Taken together, the results of the present study suggest that TTLL12 enhances SCC-25 cell survival in the presence of nitrotyrosine by disrupting nitration of the tyrosine residues of tubulin, and tubulin tyrosine nitration may be developed for the basic research of anticancer drugs.
