Immunocytochemistry/ Immunofluorescence: ATF3 Antibody [NBP1-85816] -

Immunocytochemistry/ Immunofluorescence: ATF3 Antibody [NBP1-85816] - Axotomy-induced recombination in peripherally-projecting neurons. A, Validation of an ATF3-specific antibody. The Novus antibody (NBP1-85816) produces a positive signal in nuclei of axotomized sensory neurons in ATF3+/+ mice, but not ATF3cre/cre mice. Note that the Santa Cruz antibody (C-19) labels neuronal nuclei in in the latter (inset), indicating non-specific staining. B, C, Axotomy induced reporter expression in sensory (DRG), sympathetic (stellate ganglion, SG), & motoneurons 4 d after injury. D, Reporter expression in sensory axons & motoneurons one week after injury. E, Preventing CreERT2 translocation from cytoplasm to nucleus with ICI 182780 reduces recombination in ATF3+ cells (by ∼50%). F, Recombination efficiency 16 d after injury was calculated by expressing the proportion of tracer-filled somata (labeled at the time of injury) that were also reporter (tdtomato)-positive. G, Recombination efficiencies at 4 & 16 d after injury (n = 3 for each time point) for DRG & motoneurons. Images in panels A, B, E were taken from whole mounts, those in C, D, F from cryosections.

Immunohistochemistry: ATF3 Antibody [NBP1-85816] -

Immunohistochemistry: ATF3 Antibody [NBP1-85816] - Nociceptor deletion of Tsc2 preferentially upregulates cJun & Atf3 expression in IB4-positive neurons. A, Immunohistochemistry of L4 DRG contralateral & ipsilateral to a sciatic nerve transection (SN injury) at 3 d post-injury stained for cJun, Isl1 (all neurons), & IB4. Arrows point to cJun-positive, IB4-negative neurons, & arrowheads point to cJun, IB4 double-positive neurons in uninjured Tsc2 cKO DRG. Scale bars: 50 μm. B, Quantification of percentage of cJun-positive neurons from A. C, Immunohistochemistry of L4 DRG for Atf3, Isl1 (all neurons) & IB4. Arrows point to Atf3-positive, IB4-negative neurons & arrowheads point to Atf3, IB4 double-positive neurons in uninjured Tsc2 cKO DRG. Scale bars: 50 μm. D, Quantification of percentage of Atf3-positive neurons from C. E, Western blotting of uninjured control & Tsc2 cKO L4/L5 DRG from mice receiving daily vehicle or rapamycin treatment for 3 d. F, Quantification of protein expression from E. Log2 fold change relative to uninjured control from the same biological replicate. N.S., not significant, *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001. Extended Data Figure 5-1 shows data values of mean & SEM, number of replicates, statistical tests, & values for all comparisons.

Immunocytochemistry/ Immunofluorescence: ATF3 Antibody [NBP1-85816] - Axotomy does not induce ATF3 in Schwann cells. A, Cryosections from injured DRG (inset) & distal sciatic nerve from the same mouse processed for ATF3 immunohistochemistry (Novus NBP1-85816). B, Punctate staining in the nerve proved to be non-specific fluorescence of leukocytes (note non-nuclear signal in the absence of primary antibody). C, In intact sciatic nerves, cells morphologically identical to Remak cells had at some point undergone recombination. D, Following injury, their numbers increased. E, This was attributable to their proliferation in the injured nerve (as opposed to ATF3 induction & subsequent recombination). C′, D′, Magnification of areas outlined in C & D demonstrate the spindle shaped morphology characteristic of Remak cells.
