4. The results showed SNPs near PPP2CA were associated with decreased expression of PPP2CA mRNA in PBMCs from patients with SLE and suggested that the mRNA expression of the gene may be correlated with the pathogenesis of SLE.

5. This study demonstrated an association of PPP2CA (rs10491322 and rs7704116) with systemic lupus erythematosus susceptibility in a Chinese Han population. Furthermore, the minor allele of PPP2CA rs10491322 as a risk factor was correlated with immunologic disorders for systemic lupus erythematosus.

6. RAB9 (zeige RAB9A Proteine) competes with the catalytic subunit PPP2CA in binding to PPP2R1A (zeige PPP2R1A Proteine). This competitive association has an important role in controlling the PP2A (zeige PPP2R4 Proteine) catalytic activity.

7. Results show that miR (zeige MLXIP Proteine)-199b is a tumor suppressor emerges as a potential contributing mechanism to inhibit PP2A (zeige PPP2R4 Proteine) via PP2A (zeige PPP2R4 Proteine) inhibitor SET (SET) overexpression in metastatic colorectal cancer (mCRC).

8. Data show that protein phosphatase-2A (PP2A (zeige PPP2R4 Proteine)) was upregulated in lung adenocarcinoma cell lines that were transfected with midline 1 (zeige MID1 Proteine) E3 ubiquitin-protein ligase (zeige UBE2K Proteine) (MID1 (zeige MID1 Proteine))-siRNA, suggesting MID1 (zeige MID1 Proteine) negatively regulates PP2A (zeige PPP2R4 Proteine) in lung adenocarcinoma.

9. B55alpha (zeige PPP2R2A Proteine)-PP2A (zeige PPP2R4 Proteine) mutations in acute myeloid leukemia (zeige BCL11A Proteine) have roles in leukemogenesis by promoting AKT (zeige AKT1 Proteine) T308 phosphorylation and sensitivity to AKT (zeige AKT1 Proteine) inhibitor-induced growth arrest

10. This work has significantly advanced our understanding of the RACK1 (zeige GNB2L1 Proteine)/PP2A (zeige PPP2R4 Proteine) complex and suggests a pro-carcinogenic role for the RACK1 (zeige GNB2L1 Proteine)/PP2A (zeige PPP2R4 Proteine) interaction. This work suggests that approaches to target the RACK1 (zeige GNB2L1 Proteine)/PP2A (zeige PPP2R4 Proteine) complex are a viable option to regulate PP2A (zeige PPP2R4 Proteine) activity and identifies a novel potential therapeutic target in the treatment of breast cancer.

1. Results indicate that Dlx5 (zeige DLX5 Proteine) and Runx2 (zeige RUNX2 Proteine) are critical factors for the upregulated Osterix (zeige SP7 Proteine) expression in shPP2A cells, which is considered to be important for the accelerated osteoblast differentiation in these cells.

2. Data (including data from studies in transgenic mice) suggest that Esr1 signaling promotes activation of Pp2a; here, central activation of Pp2a during estrogen replacement therapy is involved in prevention of menopause-induced obesity and glucose intolerance (that is, induced by lack of membrane-initiated Esr1 signaling). (Esr1 = estrogen receptor 1; Pp2a = protein phosphatase 2A)

3. The data also suggest that H2A.Z (zeige H2AFZ Proteine) restricts transcription, which is moderated by ANP32e (zeige ANP32E Proteine) at the promoter and gene bodies of expressed genes. Thus, ANP32e (zeige ANP32E Proteine), through inhibition of PP2A (zeige PPP2R2B Proteine), is required for nucleosomal inclusion of H2A.Z (zeige H2AFZ Proteine) and the regulation of gene expression

4. PP2A (zeige PPP2R2B Proteine) is a target of piperine, which induces autophagy in a rotenone-induced Parkinson's disease model

5. In vitro, SCF (zeige KITLG Proteine) induced the phosphorylation of p38 MAPK (zeige MAPK14 Proteine) and cofilin (zeige CFL1 Proteine), leading to the migration of cardiac stem cells.

6. We describe a novel mechanism of signal transduction enriched in medium spiny neurons of striatum that likely mediates effects of the neurotransmitter dopamine acting on these cells. We find that the protein ARPP-16, which is highly expressed in striatal medium spiny neurons, acts as a selective inhibitor of certain forms of the serine/threonine protein phosphatase, PP2A, when phosphorylated by the kinase, MAST3.

7. data show that Fyn (zeige FYN Proteine) kinase is activated after TLR4 (zeige TLR4 Proteine) triggering and exerts an important negative control on LPS (zeige TLR4 Proteine)-dependent TNF (zeige TNF Proteine) production in mast cells controlling the inactivation of PP2Ac and activation of PKCalpha (zeige PKCa Proteine)/beta necessary for the secretion of TNF (zeige TNF Proteine) by VAMP3 (zeige VAMP3 Proteine)(+) carriers

9. PP2A (zeige PPP2R2B Proteine) activation both limited and prevented inflammation and tissue injury in two direct injury models of Acute respiratory distress syndrome.

10. PP2A (zeige PPP2R2B Proteine) regulates kinetochore-microtubule attachment during meiosis I in oocyte.

1. changes in PP2A (zeige PPP2R2B Proteine) activity due to methylation and tyrosine phosphorylation occur in sperm; these changes may play an important role in the regulation of sperm function

2. The findings demonstrate an endothelial VEGF (zeige VEGFA Proteine) resistance mechanism conferred by palmitic acid, which comprises ceramide-induced, PP2A (zeige PPP2R2B Proteine)-mediated dephosphorylation of critical activation sites on enzymes central to vascular homeostasis and angiogenesis.
