A role for myosin IXb, a motor-RhoGAP chimera, in epithelial wound healing and tight junction regulation. Mol. Biol. Cell 23, 2468–2480 (2012). The recent implication of Robo signaling in brain evolution ( Cárdenas et al., 2018) has provided an important direction for future studies. The association of ROBO1 with literacy ( Hannula-Jouppi et al., 2005), which is a unique characteristic of humans, suggests that Robo signaling is involved not only in the expansion of the brain during evolution, but also in the development of higher brain functions.

The SLIT2/ROBO1 signal upregulates MMP-2 and MMP-9, thus promotes cell migration and invasion. SLIT2/ROBO1 signal recruits a ubiquitin ligase Hakai for E-cadherin ubiquitination and lysosomal degradation and thus promotes the epithelial–mesenchymal transition (EMT). The monoclonal antibody R5, which can interrupt the SLIT2/ROBO1 pathway, causes significantly suppressed cell growth and proliferation. ROBO3 promotes cancer cell growth, invasion and metastasis, which is associated with activated Wnt pathway components, β-catenin and GSK-3β, and other markers indicating the EMT, and miR-383 functions as a suppressor of ROBO3.

We asked whether NSlit2 inhibited cell spreading through its effects on RhoA, which is the most abundantly expressed Rho-family GTPase member in monocytes/macrophages 50. We used absorbance-based G-LISA assays to measure total and active RhoA levels in RAW264.7 cells. NSlit2 treatment significantly increased the active RhoA levels (Fig. 2b). We next tested the effects of TAT-C3 exoenzyme, a cell-permeable inhibitor of RhoA, RhoB, and RhoC, but not Rac1 nor Cdc42 51, on macrophage spreading. Cells incubated with TAT-C3 were significantly larger than the control counterparts (Fig. 2c, d). In macrophages treated with TAT-C3, NSlit2 no longer inhibited cell spreading (Fig. 2c, d). To verify this, we reduced the expression of RhoA using a siRNA (Supplementary Fig. 2c). Exposure to NSlit2 failed to attenuate spreading in RhoA-deficient cells (Supplementary Fig. 2d). Overall, these data indicate that NSlit2 inhibits the spreading of macrophages primarily through the activation of RhoA.

Conflict of InterestDendritic filopodium is a structure found in the early stages of spine formation, which matures into a dendritic spine. Therefore, filopodium formation is thought to be crucial for the onset of spine formation. As mentioned above, srGAPs are known to regulate filopodium formation and thus control spine formation in neurons. For BMDM isolation, 8–12-week-old mice were euthanized using the CO 2 inhalation method and femurs and tibias were cleaned and excised. The bone marrow cells were pelleted and resuspended in 1 ml of phosphate-buffered saline (PBS) and filtered through 100 µm nylon mesh. Filtered cells were centrifuged at 5500 g for 5 min and cultured in RPMI 1640 medium supplemented with 10% heat-inactivated fetal bovine serum (FBS), 25 ng/ml murine CSF1 and 1% penicillin/streptomycin/amphotericin B for 7–10 days.

Pathological stimuli such as LPS, which are associated with initial transient augmentation followed by long-term suppression of macropinocytosis in iDCs 99, 100, have also been reported to reduce Slit2 mRNA levels in tissues in vivo 101. Guan et al. reported that SLIT2 inhibits directed migration of dendritic cells in vitro and in vivo 33. SLIT2-ROBO1 signaling also inhibits podosome formation in iDCs 102. In addition to macrophages, iDCs also exhibit robust constitutive macropinocytosis, and this is their predominant means of antigen uptake 103. Interestingly, endogenous levels of Slit2 mRNA are increased following antigen sensitization in vivo 33, 35, but the physiological significance of this phenomenon remains to be elucidated. Future work will investigate whether SLIT2 causes long-term suppression of macropinocytosis in iDCs. Xian, J. et al.

SLIT2 and SLIT3 ELISA were performed using a microplate reader as per the manufacturer’s recommendations (CUSABIO CSB-E11039m and LSBio LS-F-7173, respectively). Briefly, 100 µl samples and standards were incubated in pre-coated assay wells at 37 °C for 2 h. Samples were removed and wells were then incubated with biotin antibody at 37 °C for 1 h, with avidin antibody for 1 h, and TMB substrate for 30 min. Wells were thoroughly washed three times between incubation steps. After incubation with the TMB substrate, 50 µl stop solution was added to each well and the optical density was read immediately. Wavelength correction was applied by subtracting readings at 540 nm from those at 450 nm. Statistical analyses Morlot, C. et al. Structural insights into the Slit-Robo complex. Proc. Natl Acad. Sci. USA 104, 14923–14928 (2007).Four animals were used for each treatment group. On day-0, C57BL/6J were treated with sodium periodate (200 µg in 200 µl) by a single i.p. injection to induce sterile peritonitis. Seventy-two hours after the periodate injection, saline vehicle, or NSlit2 (1 µg), or EIPA (25 mg/kg body weight in 200 µl) was administered i.p. After 1 h, MDP (10 ng) was administered i.p. After 2 h, blood was collected by intracardiac puncture under isoflurane anesthesia. Mice were euthanized immediately following the blood collection, and peritoneal exudates were collected by lavaging the peritoneal cavity with 5 ml cold PBS. Cells in the peritoneal exudate were counted using a hemocytometer. For serum collection, blood was allowed to clot for 2 h at room temperature and centrifuged at 1000 × g for 15 min. Serum aliquots were stored at −20 °C until the assay. Serum CXCL1 levels were determined by ELISA. For experiments involving in vivo Robo1N treatment, 72 h after sodium periodate treatment, saline vehicle, Robo1N (7 µg) or EIPA (25 mg/kg body weight), and Robo1N together were administered i.p. One hour later, MDP (10 ng) was administered i.p. After 2 h, blood was collected by intracardiac puncture. Mice were euthanized immediately, and the peritoneal exudates were collected. Murine CXCL1 ELISA was performed using a microplate reader as per the manufacturer’s recommendations (R&D Systems, DY453). Peritoneal membrane isolation Cai, Y. et al.

However, recently, a magnetic resonance imaging study of children with dyslexia demonstrated the abnormal morphology of neurites in the language-associated regions of the neocortex ( Caverzasi et al., 2018). In line with these observations, reduced expression of Robo1 in the embryonic mouse neocortex was shown to delay neuronal migration during development, followed by abnormal dendrite formation leading to subsequent impairment in the terminal positioning of neurons ( Gonda et al., 2013).

Serum samples were collected from C57BL/6J mice (ten males and ten females) as described before and animals were euthanized immediately after the blood collection. Under aseptic conditions, the abdominal cavity was opened by removing the skin and underlying muscle but keeping the peritoneal membrane intact. The peritoneal membrane was separated from underlying adipose tissue and organs and collected in cold PBS. The membrane was rinsed with PBS once and resuspended in RIPA buffer. Samples were homogenized with a tissue homogenizer and stored at −20 °C overnight. Two freeze-thaw cycles were performed to break cell membranes and homogenates were centrifuged at 5000 × g for 5 min at 4 °C. Supernatants were stored at −80 °C.

Dai et al. found that three major members (SLIT2, SLIT3, and ROBO1) of the SLIT/ROBO family were widely expressed in the human normal and malignant ovarian tissues and in OVCAR-3 and SKOV-3 cells. 70 However, recombinant human SLIT2 did not significantly affect SKOV-3 cell migration, and OVCAR-3 and SKOV-3 cell proliferation. SLIT2 also did not induce ERK1/2 and AKT1 phosphorylation in OVCAR-3 and SKOV-3 cells. Sanz-Pamplona et al. also demonstrated that no significant association between SLIT2 or SLIT3 level of expression and prognosis was found in colon cancer. 52 Lowery, L. A. & Van Vactor, D.
