Protein and mRNA expression of TULA-2, <t>SYK</t> <t>Y323</t> and VEGFR-2 Y1175 in ECs. ECs were incubated under normal culture conditions. ( A ) RT-qPCR showed no significant change in the mRNA levels of TULA-2 in OECs. ( B ) Western blot analysis revealed an increase in the protein levels of TULA-2 in OECs, and the phosphorylation levels of SYK Y323 and VEGFR-2 Y1175 were decreased in OECs (*P < 0.05, n = 3).

(A) Left: cartoon showing a cell culture assay in which PD-1 transduced Jurkat cells were stimulated with three types of antigen-loaded Raji B cells: (1) parental Raji cells that express neither PD-L1 nor PD-1, (2) Raji cells transduced with only PD-L1 (PD-L1+), and (3) Raji transduced with both PD-L1 and PD-1 (PD-L1+/PD-1+). On the right are FACS histograms showing PD-1 and PD-L1 surface expression of parental Jurkat cells, PD-1–mGFP transduced Jurkat (PD-1+) cells, parental Raji cells, PD-L1–mCherry transduced Raji (PD-L1+) cells, and Raji cells co-transduced with both PD-1–mGFP and PD-L1–mCherry (PD-L1+/PD-1+). a.u., arbitrary units. (B–D) Jurkat cells expressing PD-1–mGFP (PD-1+) were conjugated with Raji B cells (parental) (B), Raji cells transduced with only PD-L1–mCherry (PD-L1+) (C), or Raji cells co-transduced with PD-L1–mCherry and unlabeled PD-1 (PD-L1+/PD-1+) (D), as illustrated in the cartoon on the left (CD28 and B7 are omitted in this cartoon for simplicity). Shown on the right are confocal images of the cell conjugate acquired 2 min after cell-cell contact. mGFP and mCherry signals are shown as green and magenta, respectively. Scale bars, 10 µm. (E) Bar graph summarizing the interface enrichment indices (calculated as described in STAR Methods) of the three conditions shown in (B). Data are shown as mean ± SEM; n = 35 cells from three independent experiments. See also . (F) A representative western blot showing the levels <t>ZAP70-Y493</t> phosphorylation and p85 (PI3K regulatory subunit) co-immunoprecipitated (IP) with CD28 from the lysates of the indicated Jurkat-Raji co-culture. Jurkat cells expressing PD-1–mGFP (PD-1+) were stimulated with Raji cells (parental), Raji transduced with PD-L1–mCherry (PD-L1+), or Raji cells co-transduced with PD-L1–mCherry and PD-1–mGFP (PD-L1+/PD-1+); the times at which the co-culture was lysed are indicated (STAR Methods). WCL, whole cell lysate. (G and H) Bar graphs summarizing immunoblots in (F), including <t>pY493-ZAP70</t> immunoblot (G) and CD28 coIP p85 immunoblot (H). The optical density corresponding to each band was quantified by ImageJ and normalized to the conditions in which parental Raji cells were used as the APCs. Data are presented as mean ± SEM from three independent replicates. (I) Bar graph summarizing IL-2 levels in the medium of the indicated Jurkat-Raji co-culture, as described in (B)–(D), 24 hr after cell-cell contact. Data are presented as mean ± SEM from three independent measurements, with each run performed in triplicate.

Protein and mRNA expression of TULA-2, SYK Y323 and VEGFR-2 Y1175 in ECs. ECs were incubated under normal culture conditions. ( A ) RT-qPCR showed no significant change in the mRNA levels of TULA-2 in OECs. ( B ) Western blot analysis revealed an increase in the protein levels of TULA-2 in OECs, and the phosphorylation levels of SYK Y323 and VEGFR-2 Y1175 were decreased in OECs (*P < 0.05, n = 3).

TULA-2 knockdown positively regulates angiogenesis in vitro and increases p-SYK Y323 and p-VEGFR-2 Y1175 expression at the protein level. ( A ) Transwell assays showed that TULA-2 siRNA promoted the migration ability of OECs, and co-transfection of OECs with both si-TULA-2 and miR-25-3p inhibitors did not suppress the effect of TULA-2 upregulation on EC migration relative to the effects of siRNA-NC (n=5; Scale bar, 100 μm). ( B ) Tube formation determined on Matrigel showed that TULA-2 siRNA increased the total tube length, and co-transfection of OECs with both si-TULA-2 and miR-25-3p inhibitors did not suppress the effect of TULA-2 upregulation on EC tube formation relative to the effects of siRNA-NC (n=4; scale bar, 100 μm).

The proposed novel mechanism by which miR-25-3p affects angiogenesis in aged mice via the TULA-2/SYK/VEGFR-2 pathway. Aged ECs utilize miR-25-3p to target TULA-2 as a downstream effector to transduce signals, further downregulating and suppressing the phosphorylation of SYK Y323 and VEGFR-2 Y1175 and thus suppressing the angiogenesis pathway and inhibiting the proliferation, migration and tube formation abilities of aged ECs.
