Figure Legend Snippet: (A) In the monolayer culture, a change in cell morphology was observed in the treatment groups (Groups II-V). Treated cells showed decreased cell density and changed morphology from epithelial form to an elongated or circular shape (solid black cells). (B) In the spheroid culture, all the spheroids had a comparable size of ~300 μm, indicating no treatment effect on reducing the spheroid size, regardless of treatment. Scale bar: 200 μm. I: negative control; II: PTX 10 nM; III: TTA-A2 50 nM; IV: TTA-A2 100 nM; V: PTX 10 nM + TTA-A2 100 nM. PTX: Paclitaxel.
Techniques Used: Negative Control

Figure Legend Snippet: After eight days of the clonogenic assay, colonies were counted (A), and the percent of colonies formed was plotted on a graph (B). Each treatment group reduced the Colony Formation Efficiency of the cells significantly, with the minimum number of colonies in the combination treatment group at 12.7%, compared to the negative control, which had 24.8% of colonies. I: negative control; II: PTX 10 nM; III: TTA-A2 50 nM; IV: TTA-A2 100 nM; V: PTX 10 nM + TTA-A2 100 nM (non-significant P > 0.05, * P < 0.05, ** P < 0.01, *** P < 0.001). PTX: Paclitaxel.
Techniques Used: Clonogenic Assay, Negative Control

Figure Legend Snippet: TTA-A2, in combination with PTX, induced increased apoptosis in both monolayer (A, C) and spheroid cultures (B, D) of A549 cells. Cells stained with annexin showed green fluorescence and cells stained with PT showed red fluorescence. In spheroids, several cells showed co-staining with annexin and PI. I: negative control; II: PTX 10 nM; III: TTA-A2 50 nM; IV: TTA-A2 100 nM; V: PTX 10 nM + TTA-A2 100 nM. Scale: 100 μm (non-significant P > 0.05, * P < 0.05, ** P < 0.01, *** P < 0.001). PTX: Paclitaxel.
Techniques Used: Staining, Fluorescence, Negative Control

Figure Legend Snippet: Compared to the negative control, treatment with TTA-A2 significantly reduced Ca v 3.1 and Ca v 3.2 mRNA expression in all treatment groups. Furthermore, Pgp expression varied non-significantly among the groups (non-significant P > 0.05, * P < 0.05, ** P < 0.01, *** P < 0.001). Pgp: P-glycoprotein.
Techniques Used: Negative Control, Expressing

Figure Legend Snippet: Effect of systemic administration of THGP on the bladder pain associated with cyclophosphamide (CPA)-induced cystitis. Mice received i.p. administration of CPA at 400 mg/kg, and thereafter, i.p. administration of THGP at 30 and 100 mg/kg or TTA-A2, a T-channel inhibitor, at 1 mg/kg, 3 h after CPA treatment. After the assessment of bladder pain/referred hyperalgesia and of micturition frequency (6 h after i.p. CPA), the bladder was excised from the sacrificed mice to perform bladder weight measurement and Western blotting. (A) Upregulation of cystathionine-γ-lyase (CSE), an H 2 S-forming enzyme, in the mouse bladder 6 h after CPA treatment. The top pictures show the typical photographs of Western blotting, and bottom graphs indicate the quantified data by densitometry. (B) Effects of THGP and TTA-A2 on the bladder pain-like nociceptive behavior observed for 30 min starting 3.5 after i.p. CPA. (C) Effects of THGP and TTA-A2 on the referred hyperalgesia evaluated by von Frey tests 4 h after i.p. CPA. (D) Lack of effects of THGP and TTA-A2 on the increased bladder weight 6 h after i.p. CPA. (E) Lack of effects of THGP and TTA-A2 on the increased micturition frequency for 2 h starting 4 h after i.p. CPA. Typical photographs of visualized voiding spots and the number of voiding spots are shown. Data show the mean with S.E.M. for 5–7 mice.

Figure Legend Snippet: Effect of systemic administration of THGP on the pancreatic pain associated with cerulein-induced pancreatitis in mice. Mice received repeated i.p. injection of cerulein at 50 μg/kg at 1-h intervals, 6 times in total. THGP at 100 mg/kg or TTA-A2 at 1 mg/kg was administered i.p. 5 min after the final (6th) cerulein injection, and the referred hyperalgesia was repeatedly evaluated 5.5, 6 and 6.5 h after the onset of repeated cerulein injections (i.e. 0.5, 1 and 1.5 h after the final cerulein injection). Seven hours after the onset of repeated cerulein injections, the blood was withdrawn from the anesthetized mice for the assessment of plasma amylase activity, and the pancreatic tissue was excised from the sacrificed mice afterwards, to perform pancreatic weight measurement and Western blotting. (A) Upregulation of cystathionine-γ-lyase (CSE), an H 2 S-forming enzyme, in the mouse pancreas 7 h after the onset of repeated cerulein injections. The top pictures show the typical photographs of Western blotting, and bottom graphs indicate the quantified data by densitometry. (B) Effects of THGP and TTA-A2 on the referred hyperalgesia evaluated repeatedly by von Frey test 5.5–6.5 h after the onset of repeated cerulein injections. (C, D) Lack of effect of THGP and TTA-A2 on the increased pancreatic weight (C) and plasma amylase activity (D) in cerulein-treated mice. V, vehicle. Data show the mean with S.E.M. from 9 mice. **P < 0.01, ***P < 0.001 vs. V + V; †P < 0.05, ††P < 0.01 vs. V + cerulein.

( A – F ) In ddY mice, 6-prenylnaringenin (6-PNG), a hop-derived T-type Ca 2+ channel blocker, or KTt-45, a derivative of 6-PNG, at 10 and 30 mg/kg was administered i.p. 3 h 15 min after i.p.
