丝氨酸蛋白酶参与癌症发展的许多阶段,促进肿瘤细胞生长、侵袭和转移,天然存在的丝氨酸蛋白酶抑制剂已显示出作为潜在抗癌治疗剂的前景。作为潜在治疗剂的抑制剂的最佳设计需要鉴定参与疾病进展的特定丝氨酸蛋白酶和负责肿瘤促进特性的功能靶标。在这里,我们使用在3D器官型培养条件下生长的HMT-3522乳腺癌进展系列,发现丝氨酸蛋白酶抑制剂导致恶性T4-2细胞的形态逆转,通过抑制增殖和形成具有基础标志物极化的腺泡结构进行评估,暗示丝氨酸蛋白酶活性在其恶性生长行为中。我们确定PRSS 3/中胰蛋白酶上调T4-2细胞相比,其非恶性的祖细胞,并显示,敲除PRSS 3减弱,和治疗与重组纯化的中胰蛋白酶增强,恶性生长表型。使用蛋白质组学方法,我们确定CD 109作为中胰蛋白酶的功能性蛋白水解靶标。我们的研究确定了乳腺癌生长和进展的新介质和效应器。
Serine proteases have been implicated in many stages of cancer development, facilitating tumor cell growth, invasion, and metastasis, and naturally occurring serine protease inhibitors have shown promise as potential anticancer therapeutics. Optimal design of inhibitors as potential therapeutics requires the identification of the specific serine proteases involved in disease progression and the functional targets responsible for the tumor-promoting properties. Here, we use the HMT-3522 breast cancer progression series grown in 3D organotypic culture conditions to find that serine protease inhibitors cause morphological reversion of the malignant T4-2 cells, assessed by inhibition of proliferation and formation of acinar structures with polarization of basal markers, implicating serine protease activity in their malignant growth behavior. We identify PRSS3/mesotrypsin upregulation in T4-2 cells as compared to their nonmalignant progenitors, and show that knockdown of PRSS3 attenuates, and treatment with recombinant purified mesotrypsin enhances, the malignant growth phenotype. Using proteomic methods, we identify CD109 as the functional proteolytic target of mesotrypsin. Our study identifies a new mediator and effector of breast cancer growth and progression.
