Figure Legend Snippet: Effect of candesartan or telmisartan but not amlodipine on TRPC expression in mesenteric arterioles. Long-term administration of angiotensin AT1 receptor antagonist telmisartan or candesartan, but not of calcium channel blocker amlodipine reduces TRPC1, TRPC3 and TRPC5 channel protein expression in vivo. The angiotensin AT1 receptor antagonist telmisartan (5 mg/kg per day) or candesartan (4 mg/kg per day), calcium channel blocker amlodipine (10 mg/kg per day), or placebo were administered to SHR by gavage for 16 weeks. Representative immunoblottings of TRPC channel protein expressions in mesenteric arterioles from treated SHR (Fig. 7A) and summary data are shown (Fig. 7B). * P

![Schematic model illustrating the cardioprotection effect of Ucn-2 from I/R injuries. Left panel summarizes the effect of I/R in rats. I/R promotes fibrosis, hypertrophy and increases the infarct size. I/R also decreases heart’s contractility (ejection fraction and cell shortening) and [Ca 2+ ] i transients. In addition, we demonstrated that I/R potentiates SOCE and upregulated several ion channels, such as Orai1 and TRPC5. Right panel illustrates the effects of the addition of Ucn-2 at the onset of reperfusion. Ucn-2 inhibits fibrosis and decreases the infarct size; it recovers significantly heart’s contraction and the amplitude of [Ca 2+ ] i transients.

Figure Legend Snippet: Schematic model illustrating the cardioprotection effect of Ucn-2 from I/R injuries. Left panel summarizes the effect of I/R in rats. I/R promotes fibrosis, hypertrophy and increases the infarct size. I/R also decreases heart’s contractility (ejection fraction and cell shortening) and [Ca 2+ ] i transients. In addition, we demonstrated that I/R potentiates SOCE and upregulated several ion channels, such as Orai1 and TRPC5. Right panel illustrates the effects of the addition of Ucn-2 at the onset of reperfusion. Ucn-2 inhibits fibrosis and decreases the infarct size; it recovers significantly heart’s contraction and the amplitude of [Ca 2+ ] i transients. Moreover, Ucn-2 blocks I/R-evoked exacerbated SOCE and it inhibits I/R-induced Orai1 and TRPC5 upregulation and interaction.

Figure Legend Snippet: Overexpression of Ca V 3.1 T-type calcium channels in KLHL1-KO mice hypothalamus. (A) Pleiotropic signaling of leptin in POMC hypothalamic neurons. Leptin binding to its receptor LRb results in the downstream activation of JAK2. STAT3 is subsequently phosphorylated and mobilized to the nucleus resulting in de novo gene expression. Activation of insulin receptor substrate (IRS) stimulates Akt- and mTOR pathways via activation of phosphorylated PI3K and the production of PIP3. The activation of PLCλ1 by PIP3 mediates the activation of TRPC1/5 channels, recruiting T-type CaV3.1/2 channels thought membrane depolarization. (B) Western blot analysis from hypothalamic extracts assessing TRPC1, TRPC5, Ca V 3.2 and Ca V 3.1 channel levels; Ca V 3.1 protein levels are doubled in KLHL1-KO hypothalamus. Bars show densitometric quantification normalized to GAPDH. Data represent means ± S.E.M (TRPC1, n = 3 each; TRPC5, n = 4 each; Ca V 3.2, n = 5 each; Ca V 3.1, n = 5 each). * P

Figure Legend Snippet: The TRPC5 antibody occludes the effect of FFA in hcrt/orx neurons. (A) Transient (2 min) bath-application of 100 µM flufenamic acid (FFA), a non specific blocker of cationic currents, produces a strong membrane hyperpolarization and cessation of firing; inset: in voltage-clamp this hyperpolarization corresponds to an outward current. (B) Voltage-clamp ramps in absence (Ctrl) and presence (FFA) of flufenamic acid. The subtraction of voltage-clamp ramps shown in the inset suggests the presence of a voltage-dependent cationic current. (C–D) In hcrt/orx neurons loaded with a TRPC5 antibody, bath-application of FFA had only a small additional effect either in current-clamp (C) or in voltage-clamp (D).
Techniques Used:
Figure Legend Snippet: Dual immunohistochemical staining for TRPC5 and hcrt/orx. (A–B) Photomicrographs from a dual-immunostained section combining an hcrt/orx antibody from Santa Cruz (A) and a TRPC5 antibody from Alomone Labs (B).

Some hcrt/orx cells do not express TRPC5, as shown by an example indicated with a single circle. It is noteworthy that many hcrt/orx-negative cells also expressed TRPC5, as shown by an example indicated with a downward arrow (in panels A and B).

Figure Legend Snippet: The depolarized state of hcrt/orx neurons is blocked by a TRPC5 antibody. (A–C) In voltage-clamp configuration, intracellular application of either a TRPC1 (A) or a TRPC3 (B) or a TRPC4 (C) antibody (AbTRPC1, AbTRPC3 and AbTRPC4 respectively, all from Alomone Labs) has no effect on the current needed to clamp the cell at −50 mV. (D–E) Intracellular application of a TRPC5 antibody (Alomone Labs), in contrast, induces an outward current (D) that is blocked by co-application of a TRPC5 antigen (E). (F–G) In current-clamp configuration, intracellular application of a TRPC5 antibody alone (from either Alomone Labs (F) or NeuroMab (inset in F) induces an important membrane hyperpolarization and cessation of firing. In contrast, intracellular co-application of the TRPC5 antibody (Alomone Labs) together with its appropriate antigen (AgTRPC5) has no effect (G, to compare with F). (H) Voltage-clamp ramps in absence (Ctrl) and presence of a TRPC5 antibody (AbTRPC5, Alomone Labs). In the inset, subtraction of voltage-clamp ramps (Ctrl - AbTRPC5) suggests the presence of a voltage-dependent TRPC5 current.

Figure Legend Snippet: The depolarized state of hcrt/orx neurons is blocked by a TRPC5 antibody. (A–C) In voltage-clamp configuration, intracellular application of either a TRPC1 (A) or a TRPC3 (B) or a TRPC4 (C) antibody (AbTRPC1, AbTRPC3 and AbTRPC4 respectively, all from Alomone Labs) has no effect on the current needed to clamp the cell at −50 mV. (D–E) Intracellular application of a TRPC5 antibody (Alomone Labs), in contrast, induces an outward current (D) that is blocked by co-application of a TRPC5 antigen (E). (F–G) In current-clamp configuration, intracellular application of a TRPC5 antibody alone (from either Alomone Labs (F) or NeuroMab (inset in F) induces an important membrane hyperpolarization and cessation of firing. In contrast, intracellular co-application of the TRPC5 antibody (Alomone Labs) together with its appropriate antigen (AgTRPC5) has no effect (G, to compare with F). (H) Voltage-clamp ramps in absence (Ctrl) and presence of a TRPC5 antibody (AbTRPC5, Alomone Labs). In the inset, subtraction of voltage-clamp ramps (Ctrl - AbTRPC5) suggests the presence of a voltage-dependent TRPC5 current.

Figure Legend Snippet: The TRPC5 antibody occludes the effect of FFA in hcrt/orx neurons. (A) Transient (2 min) bath-application of 100 µM flufenamic acid (FFA), a non specific blocker of cationic currents, produces a strong membrane hyperpolarization and cessation of firing; inset: in voltage-clamp this hyperpolarization corresponds to an outward current. (B) Voltage-clamp ramps in absence (Ctrl) and presence (FFA) of flufenamic acid. The subtraction of voltage-clamp ramps shown in the inset suggests the presence of a voltage-dependent cationic current. (C–D) In hcrt/orx neurons loaded with a TRPC5 antibody, bath-application of FFA had only a small additional effect either in current-clamp (C) or in voltage-clamp (D).

Figure Legend Snippet: Dual immunohistochemical staining for TRPC5 and hcrt/orx. (A–B) Photomicrographs from a dual-immunostained section combining an hcrt/orx antibody from Santa Cruz (A) and a TRPC5 antibody from Alomone Labs (B). Examples of double labelled hcrt/orx-TRPC5 cells are indicated by white arrowheads and one such cell by a double circle (enlarged in the corresponding small panels to the right). Some hcrt/orx cells do not express TRPC5, as shown by an example indicated with a single circle. It is noteworthy that many hcrt/orx-negative cells also expressed TRPC5, as shown by an example indicated with a downward arrow (in panels A and B).

Figure Legend Snippet: Schematic model illustrating the cardioprotection effect of Ucn-2 from I/R injuries. Left panel summarizes the effect of I/R in rats. I/R promotes fibrosis, hypertrophy and increases the infarct size. I/R also decreases heart’s contractility (ejection fraction and cell shortening) and [Ca 2+ ] i transients. In addition, we demonstrated that I/R potentiates SOCE and upregulated several ion channels, such as Orai1 and TRPC5. Right panel illustrates the effects of the addition of Ucn-2 at the onset of reperfusion. Ucn-2 inhibits fibrosis and decreases the infarct size; it recovers significantly heart’s contraction and the amplitude of [Ca 2+ ] i transients. Moreover, Ucn-2 blocks I/R-evoked exacerbated SOCE and it inhibits I/R-induced Orai1 and TRPC5 upregulation and interaction.
