Statistical analysis of phospho-Akt/total-Akt, phospho-mTOR/total-mTOR and phospho-GSK3/total-GSK3 densitometry are shown right. To investigate the underlying mechanism of the association of Tuft1 with TC, we performed GESA analysis and found that Tuft1 was closely related with Akt-mTOR and Akt-GSK3 signaling (Figure 3E). and 12 normal tissue cases. By quantitative PCR, we found that the expression level of was significantly upregulated in TC tissues (Physique 1A). In 12 paired TC and normal tissues, mRNA expression was consistently higher in TC tissues than in paired normal tissues (Physique 1B). The protein expression of Tuft1 was also found to be significantly upregulated in TC tissues in 12 of these tissue sample pairs (Physique 1C).

(E and F) Kaplan-Meier analysis of overall survival (OS) (E, = 0.015) and disease-free survival (DFS) (F, = 0.045) for the expression of Tuft1. We then used a TC tissue microarray (n = 154) to investigate the correlation between Tuft1 expression and patient prognoses. Consistent with our other findings, the expression of Tuft1 was upregulated in 75.40% of TC tissues (Figure 1D). The high expression of Tuft1 was positively correlated with poor overall survival (OS) (= 0.044) and disease-free survival (DFS) (= 0.045) (Figure 1E and ?and1F1F). Tuft1 knockdown suppresses the invasion and proliferation and promotes the apoptosis of TC cells To further investigate the biological functions of Tuft1 in TC, we examined the expression level of in five human TC cell lines, including TPC-1, SW579, K1, BCPAP, and TT cells, and the human normal thyroid cell line HT-ori3. As shown in Physique 2A, expression was high in TPC-1 and SW579 cells. We therefore silenced Tuft1 using siRNA (si-Tuft1-1 and si-Tuft1-2) or transfected unfavorable control (NC) siRNA in TPC-1 and SW579 cells. Through western blotting analysis, we found that Tuft1 was successfully silenced in TPC-1 (Physique 2B) and SW579 (Physique 2C) cells.

We then investigated the biological function of Tuft1 in the invasion of TC cells. By using Transwell? Matrigel invasion assays, we found that knockdown of Tuft1 for 48 hours suppressed the invasiveness of TPC-1 (Physique 2D) and SW579 (Physique 2E) cells. We then investigated the role of Tuft1 in the proliferation Anamorelin HCl of TC cells. Using the CCK-8 cell viability assay, we found that the cell viability of TPC-1 and SW579 Anamorelin HCl cells was significantly suppressed by knockdown of Tuft1 for 24, 48, and 72 hours (Physique 2F and ?and2G).2G). Moreover, by annexin V detection, we found that knockdown of Tuft1 promoted the apoptosis of TPC-1 (Physique 2H) and SW579 (Physique 2I) cells after 48 hours..Moreover, by annexin V detection, we found that knockdown of Tuft1 promoted the apoptosis of TPC-1 (Physique 2H) and SW579 (Physique 2I) cells after 48 hours. Knockdown of Tuft1 attenuates tumor growth in vivo and decreases the phosphorylation of Akt and mTOR, and GSK3 signaling TPC-1 cells were subcutaneously injected into the lower back of male NU/NU mice. GSK3 inhibitor (CHIR-98014) only abrogated rTuft1 Anamorelin HCl protein-induced proliferation and apoptosis inhibition. These results suggest that Tuft1 promotes TC cell invasion and proliferation, and suppresses apoptosis through the Akt-mTOR or Akt-GSK3 signaling pathway. In the future, Tuft1 may serve as a potential therapeutic target for TC. in TC tissues, we used 16 TC cases and 12 normal tissue cases.
