Figure 3, Supplemental Figure 5 (younger age group), Supplemental Figure 6 (older age group), and Supplemental Tables 5 and 8 reveal an overall similar pattern of Adnp genotype–and NAP treatment–regulated human and mouse protein product interactions across ages with Akt1 (the mosaic mutations of which lead to the Proteus syndrome, characterized by the overgrowth of skin, connective tissue, brain, and other tissues; ref. 37) and discs large MAGUK scaffold protein 4 (Dlg4, also known as Psd95), a key regulator of synaptic plasticity (see above) that plays central roles associated with ADNP and NAP function.

In the 3-month-old hippocampi (Figure 4B), we found significant sex-dependent changes for Adnp+/– gene regulation and NAP rescue in the following genes in male mice: (a) apolipoprotein E (Apoe), the lead gene for Alzheimer’s disease risk, which was shown before to be a major gene regulated by ADNP (10, 13); (b) Gm21949, which is suggested to play a role in calcium-mediated responses, action potential conduction in myelinated cells, and axonal outgrowth and guidance (6); (c) lipase A (Lipa), which is related to lipid metabolism and was previously shown to be regulated by the Adnp genotype in mice (3); (d) autism-associated neuroligin 2 (Nlgn2), a postsynaptic membrane cell adhesion protein that mediates the formation and maintenance of synapses between neurons (12); (e) paired box protein 6 (Pax6), a key regulator in glutamatergic neuronal differentiation (38) and cortical development (39), which was shown before by us to be regulated by ADNP (complete knockout of Adnp rendered Pax6 expression undetectable in the brain primordium, contrasting with increased expression in Adnp+/– embryos [ref. 1] and in subcortical brain domains of 2-month-old male Adnp+/– mice [ref. 3]); and (f) Wolframin endoplasmic reticulum transmembrane glycoprotein (Wfs1), which is associated with neurodegeneration and cellular calcium homeostasis regulation and was previously shown to be regulated by NAP (34).

Our original cell culture results showed NAP protection against excitotoxicity over a broad concentration range, suggesting an involvement of the glutamatergic system in ADNP/NAP activity PubMed:30664622

In this respect, our previous data associated postsynaptic density protein 95 (PSD95, also known as DLG4) with ADNP/NAP activity PubMed:30664622

On the other hand, chronic treatment with an eight-amino-acid peptide snippet from ADNP (NAP), also known as davunetide, restored both Beclin1 and ADNP mRNA levels along with ADNP-LC3 interaction, thus providing neuroprotection while ameliorating schizophrenic-like behavioral and cognitive deficits in Map6+/- mice PubMed:30061532

The measurements showed similar patterns in both tested brain areas, with Adnp deficiency resulting in substantial decreases in spine density (male and female mice) and increases in PSD95-asymmetric shaft synapses (males only, as indicated by increased localization of PSD95 in dendritic shafts rather than spines), which were all rescued by NAP treatment. PubMed:30106381

In hippocampal CA1 pyramidal cells, all dendritic spine subtypes were reduced in the Adnp+/– mice, except for the thin spines observed in males. The spine loss was rescued by NAP treatment, except for the stubby spines seen in males (Supplemental Figure 1). PubMed:30106381

Supplemental Figure 2 shows the cortical spine data indicating a significant genotype effect (P < 0.01) and NAP rescue for all subtypes in males (P < 0.05). PubMed:30106381

PubMed:30106381

This genotype- and sex-dependent pathology also extended to the cortex, with increased PSD95 shaft synapse density in Adnp+/– males compared with Adnp+/– females (P < 0.01), and was rescued by NAP treatment. PubMed:30106381

Importantly, in males, NAP treatment did not affect PSD95 shaft synapse density in either tested region (Supplemental Figures 3 and 4, insets). PubMed:30106381

Furthermore, NAP treatment increased PSD95 shaft synapse volume in both tested brain regions (Supplemental Figures 3 and 4, insets, P < 0.05). PubMed:30106381

In female mice, NAP treatment significantly decreased shaft synapses PubMed:30106381

Interestingly, we found that shaft synapse densities (immature synapses) were decreased in the female cortex following NAP treatment (Supplemental Figure 4, P < 0.05). PubMed:30106381

Measurements of PSD95 for excitatory shaft synapse volumes (indicative of synaptic maturation) showed significant increases in Adnp+/– mice in both hippocampus and cortex (P < 0.05), but not in the male mouse cortical spines. We observed a further increase with NAP treatment in female mice only, suggesting a compensatory effect (Supplemental Figures 1 and 2, insets). PubMed:30106381

In the mature cerebral cortex, only histone cluster 1 H3 family member B (Hist1h3b), which was one of the major transcripts downregulated in the hippocampi of 5-month-old Adnp+/–mice compared with Adnp+/+ mice (6, 17), was found here to be downregulated in the female Adnp+/– mouse. This effect was now shown to be reversed by NAP treatment (Figure 4B). PubMed:30106381

In male mice, the ATP-binding cassette subfamily F member 3 (Abcf3), bone morphogenetic protein 4 (Bmp4), cadherin 17 (Cdh17), lysine demethylase 5d (Kdm5d), Kruppel-like factor 1 (Klf1), and period circadian regulator 1 (Per1) were upregulated as a consequence of Adnp haploinsufficiency and rescued by NAP PubMed:30106381

Likewise, mechanistic target of rapamycin (Mtor), which has been linked to cellular regulation, protein translation, autophagy, and the actin cytoskeleton (43–45), was also found to be regulated by ADNP and NAP PubMed:30106381

Importantly, negative geotaxis, a test used to investigate motor coordination and vestibular sensitivity, showed delayed development in Adnp+/– mice and normalization with NAP treatment (Figure 5D). PubMed:30106381

Specifically, the standing time and step cycle parameters indicated better performance in males, with significant impairments seen in Adnp+/– mice and amelioration with NAP treatment (Figure 6, C and D). PubMed:30106381

We then measured the latency to fall off an inverted cage lid (hanging wire) and found a highly significant impairment (decreased latency) in male Adnp+/– mice and a complete reversal with NAP treatment (Figure 7A). The females were not affected in this behavior, indicating sex differences in motor behavior and development in the haploinsufficient mice PubMed:30106381

Likewise, Adnp+/– males, but not females, showed significantly reduced grip strength that was completely reversed by NAP treatment (Figure 7B). PubMed:30106381

Here, we found that object recognition memory was normalized following NAP treatment in Adnp+/– mice (Figure 7C) and that NAP treatment did not change the behavior of normal Adnp+/+ mice (Supplemental Figure 14). PubMed:30106381

This was coupled with deficits in olfactory function in the Adnp+/– females, but not males, with the female mice exhibiting impaired odor discrimination that was also restored by NAP treatment (Figure 7E; for more detail, see Supplemental Figure 14). PubMed:30106381

We have previously shown essentially no significant NAP effects on behavior in the Adnp+/+ mice PubMed:30664622

We have also extended the experiments to female mice, and interestingly, in the social recognition test CB- or NAP-treated females displayed significant preference to mice rather than objects (Supplemental Fig. S2C), unlike previous findings with the “DD” formulation. PubMed:30664622

Furthermore, in both sexes, Adnp haploinsufficiency showed significantly inhibited social memory, which was completely ameliorated by NAP treatment (Fig. 2d, males and Supplemental Fig. S2D, females). PubMed:30664622

Given the fact that children carrying ADNP mutations (ADNP syndrome children) exhibit motor impairments, we also utilized the hanging wire test to measure potential impairments and amelioration by NAP. Results showed a significant impairment due to Adnp haploinsufficiency and amelioration by NAP treatment (Fig. 2f) PubMed:30664622

Our original cell culture results showed NAP protection against excitotoxicity over a broad concentration range, suggesting an involvement of the glutamatergic system in ADNP/NAP activity PubMed:30664622

In females, hippocampal VGLUT1 was not affected by the Adnp genotype or NAP treatment (Supplemental Fig. S4A) PubMed:30664622

In the cerebral cortex, female Adnp+/− mice exhibited significantly reduced VGLUT1 expression, with no effect for NAP (Supplemental Fig. S4B). PubMed:30664622

When using area counting, NAP treatment was shown to provide full protection against VGLUT1 decreases in both the hippocampus and the cerebral cortex (Fig. 4f, h), whereas in terms of intensity changes in VGLUT1 expression, NAP effect was significant in the hippocampus (Fig. 4g), and exhibited a trend of improvement in the cortex (Fig. 4i). PubMed:30664622

In males, complementing DTI data (Fig. 3) our results (Fig. 4a) revealed that in Adnp+/− mice, Slc17a7 (VGLUT1) gene expression was significantly decreased in the hippocampus, and completely reversed by NAP treatment (Fig. 4a), while in the cerebral cortex, NAP treatment resulted in a small, albeit significant decrease in the VGLUT1 transcript (Fig. 4b).

In this respect, our previous data associated postsynaptic density protein 95 (PSD95, also known as DLG4) with ADNP/NAP activity PubMed:30664622

NAP has been shown to ameliorate Adnp deficiencies in the haploinsufficient mouse model [25], mechanistically by enhancing ADNP association with its microtubule and autophagy targets PubMed:30008470

These results indicate that restoration of ADNP function by NAP administration rescues the wild type phenotype of the Adnp+/− mice, by reversing the abnormal increase in alcohol intake seen in Adnp haploinsufficient female mice PubMed:30008470
