Article Title: TGFβ induces an atypical EMT to evade immune mechanosurveillance in lung adenocarcinoma dormant metastasis.
Article Snippet: .. For analysis of TGFβ responses, cells were cultured in media containing 2% FBS and incubated with SB-505124 (2.5 μM; Millipore Sigma, S4696-5MG), 100 pM TGFβ1 (R&D Systems) or 100 pM TGFβ2 (R&D Systems, 302-B2-002) for the indicated period of time. .. For analysis of Wnt-3a response, cells were cultured in media containing 2% FBS and treated with recombinant human Wnt-3a protein (R&D Systems, 5036-WN-010) at a final concentration of 200 ng ml−1 for 2 h. Gene knockout, knockdown and overexpression constructs CRISPR-mediated knockouts were generated by cloning sgRNAs into the Guide-it CRISPR–Cas9 vector (Red, TaKaRa, 632602), transfecting the construct into cells and isolating and expanding the cells with knockouts from single-cell colonies.

Proteomic analysis showed that expressions of TXNDC5 and ECM proteins were upregulated in TGFβ2-treated HTM cells. HTM cells were starved with serum-free DMEM/F12 medium for 24 hours and then treated with TGFβ2 (5 ng/mL) for 48 hours. (A) Changes of protein expression after TGFβ2 treatment in HTM cells were represented by volcano plots (≥1.2-fold difference: upregulated genes [ red ] and downregulated genes [ blue ]). Violin plots showed the TGFβ2-induced significant changes in TXNDC5 (B) , LN (C) , FN (D) , COL4A1 (E) , and COL4A2 (F) . ** P < 0.01; *** P < 0.001. (G) KEGG analysis indicated multiple metabolic and signal pathways, including ECM-receptor interaction, were changed markedly.

Schematic representation of the involvement of CMA lysosomal degradation pathway of TXNDC5 in TM ECM protein accumulation. Treatment with TGFβ2 increased the expression of TXNDC5 and further promoted the expression of TGFβR2, which in turn promoted the increase of ECM protein. Intracellularlly, mutual recognition of the molecular chaperone Hsc70 with TXNDC5 protein and synergism with LAMP2A molecule promotes the entry of TXNDC5 protein into lysosomal degradation, and activation of CMA activity by AR7 leads to the entry of more TXNDC5 into lysosomal degradation, thereby reducing ECM accumulation. The expression of TXNDC5 in the aqueous humor of POAG patients was significantly higher than that of non-POAG patients. In the Ad.hTGFβ 226/228 -mediated high IOP mouse model, injection of si-TXNDC5 significantly improved Ad.hTGFβ 226/228 -mediated high IOP and ECM accumulation in TM tissue.
