Abstract

Arginine methyltransferase PRMT7 is associated with human breast cancer metastasis. Endosomal FAK signalling is critical for cancer cell migration. Here we identified the pivotal roles of PRMT7 in promoting endosomal FAK signalling activation during breast cancer metastasis. PRMT7 exerted its functions through binding to scaffold protein SHANK2 and catalyzing di-methylation of SHANK2 at R240. SHANK2 R240 methylation exposed ANK domain by disrupting its SPN-ANK domain blockade, promoting in co-accumulation of dynamin2, talin, FAK, cortactin with SHANK2 on endosomes. In addition, SHANK2 R240 methylation activated endosomal FAK/cortactin signals in vitro and in vivo. Consistently, all the levels of PRMT7, methylated SHANK2, FAK Y397 phosphorylation and cortactin Y421 phosphorylation were correlated with aggressive clinical breast cancer tissues. These findings characterize the PRMT7-dependent SHANK2 methylation as a key player in mediating endosomal FAK signals activation, also point to the value of SHANK2 R240 methylation as a target for breast cancer metastasis.

Ethics

Animal experimentation: All animal works were conducted in accordance with the IACUC guidelines and with the protocol approved by the IACUC at the Northeast Normal University, reference assurance number AP2013011.

Human subjects: Human breast tumour specimens were obtained from the Second Hospital of Jilin University, China. All the breast cancer tissue samples were collected from 27 patients enrolled on pathology department of the Second Hospital of Jilin University. All the samples were diagnosed by the pathology department of the Second Hospital of Jilin University to determine the stage and subtype of the breast tumour. This experiment is an immunohistochemical study, no informed consent was needed due to the use of post-diagnostic left-over material. Ethical approval was obtained from the Ethics Review Committee of the Second Hospital of Jilin University (2019-107).

    Luminal epithelial cells integrate variable responses to aging into stereotypical changes that underlie breast cancer susceptibility

    Rosalyn W Sayaman, Masaru Miyano ... Mark A LaBarge
    Research Article Updated

    Effects from aging in single cells are heterogenous, whereas at the organ- and tissue-levels aging phenotypes tend to appear as stereotypical changes. The mammary epithelium is a bilayer of two major phenotypically and functionally distinct cell lineages: luminal epithelial and myoepithelial cells. Mammary luminal epithelia exhibit substantial stereotypical changes with age that merit attention because these cells are the putative cells-of-origin for breast cancers. We hypothesize that effects from aging that impinge upon maintenance of lineage fidelity increase susceptibility to cancer initiation. We generated and analyzed transcriptomes from primary luminal epithelial and myoepithelial cells from younger <30 (y)ears old and older >55 y women. In addition to age-dependent directional changes in gene expression, we observed increased transcriptional variance with age that contributed to genome-wide loss of lineage fidelity. Age-dependent variant responses were common to both lineages, whereas directional changes were almost exclusively detected in luminal epithelia and involved altered regulation of chromatin and genome organizers such as SATB1. Epithelial expression variance of gap junction protein GJB6 increased with age, and modulation of GJB6 expression in heterochronous co-cultures revealed that it provided a communication conduit from myoepithelial cells that drove directional change in luminal cells. Age-dependent luminal transcriptomes comprised a prominent signal that could be detected in bulk tissue during aging and transition into cancers. A machine learning classifier based on luminal-specific aging distinguished normal from cancer tissue and was highly predictive of breast cancer subtype. We speculate that luminal epithelia are the ultimate site of integration of the variant responses to aging in their surrounding tissue, and that their emergent phenotype both endows cells with the ability to become cancer-cells-of-origin and represents a biosensor that presages cancer susceptibility.

    TIPE drives a cancer stem-like phenotype by promoting glycolysis via PKM2/HIF-1α axis in melanoma

    Maojin Tian, Le Yang ... Peiqing Zhao
    Research Article

    TIPE (TNFAIP8) has been identified as an oncogene and participates in tumor biology. However, how its role in the metabolism of tumor cells during melanoma development remains unclear. Here, we demonstrated that TIPE promoted glycolysis by interacting with pyruvate kinase M2 (PKM2) in melanoma. We found that TIPE-induced PKM2 dimerization, thereby facilitating its translocation from the cytoplasm to the nucleus. TIPE-mediated PKM2 dimerization consequently promoted HIF-1α activation and glycolysis, which contributed to melanoma progression and increased its stemness features. Notably, TIPE specifically phosphorylated PKM2 at Ser 37 in an extracellular signal-regulated kinase (ERK)-dependent manner. Consistently, the expression of TIPE was positively correlated with the levels of PKM2 Ser37 phosphorylation and cancer stem cell (CSC) markers in melanoma tissues from clinical samples and tumor bearing mice. In summary, our findings indicate that the TIPE/PKM2/HIF-1α signaling pathway plays a pivotal role in promoting CSC properties by facilitating the glycolysis, which would provide a promising therapeutic target for melanoma intervention.
