All experiments were performed with HeLa cells44 (link) (obtained from E.V. Makayev, Nanyang Technological University, Singapore) either stably or transiently transfected with a plasmid for bicistronic expression of mCherry–eDHFR and indicated Haloenzyme constructs (see below). CENPB and mitochondria experiments were performed with stable cell lines; centrosome and kinetochore experiments were performed by transient transfection. Stable cell lines were created by recombinase-mediated cassette exchange using the HILO recombinase-mediated cassette exchange system44 (link) (obtained from E.V. Makeyev, Nanyang Technological University, Singapore). Briefly: a monoclonal acceptor cell line with LoxP and Lox2272 recombination sites at a single chromosomal locus was cotransfected with a donor plasmid containing a transgenic cassette flanked by LoxP and Lox2272 sites and a second plasmid expressing Cre recombinase, followed by selection for a marker in the donor cassette. Cells were cultured in growth medium (Dulbecco’s Modified Eagle’s medium with 10% FBS and penicillin–streptomycin) at 37 °C in a humidified atmosphere with 5% CO2. Cells at ~ 60% confluency in a single well of a 6-well plate were transfected with 1 µg of donor plasmid + 10 ng of Cre plasmid pEM784 (see below for plasmid details) using 3 µl of Fugene 6 (Promega). Two days after transfection, 1 µg ml−1 puromycin was added to the growth medium for the selection of stable cell lines. Transient transfections were performed as above using 3 µl of Fugene 6 and 1 µg of plasmid DNA, 40 h before experiment.

The complete rat MeCP2 ORF as well as the DNA-binding domain of human CENPB (aa 1–169; Shelby et al., 1996 (link)) were fused in frame at the NH2 terminus of the enhanced YFP (pEYFP-N1 vector; CLONTECH Laboratories, Inc.). The YFP-containing part from MeCP2-YFP fusion was cut out and replaced by either enhanced GFP (isolated from pEGFP-N1 vector; CLONTECH Laboratories, Inc.) or mRFP1 (Campbell et al., 2002 (link)) to construct MeCP2-GFP and MeCP2-mRFP1, respectively. MeCP2 deletion mutants were generated from the above plasmids using conveniently located restriction enzyme sites or by PCR amplification using primers including compatible restriction sites (primer sequences are available upon request). The complete human DNA ligase I ORF was fused in frame at the COOH terminus of the DsRed1 gene (pDsRed1-C1; CLONTECH Laboratories, Inc.) (Easwaran et al., 2004 (link), 2005 (link)). The GFP-HP1α (human HP1α; Cheutin et al., 2003 (link)); GFP-MBD2 (human MBD2a; Tatematsu et al., 2000 (link)); MBD1-GFP, MBD4-GFP, and GFP-MBD3 (mouse cDNAs for MBD1, MBD4, and MBD3; Hendrich and Bird, 1998 (link)); and FLAG-HP1β (FLAG epitope–tagged mouse HP1β; Nielsen et al., 2001 (link)) were as described. Correct expression of all fusions in mammalian cells was checked by Western blot analysis as described before (Cardoso et al., 1997 (link); Easwaran et al., 2005 (link)).

To select sequences for the first N-zip library, only genes with significant enrichment (adjusted P < 0.05) in the analyzed primary neuronal datasets were considered as candidates to generate a list of genes with reliable neurite localization. This selection was further restricted to genes for which an enrichment value could be calculated in our PCN system (log2FC not NA). Then, genes with (1) a significant enrichment in at least four datasets; (2) median log2FC > 1; and (3) either mean log2FC > 1 or a positive log2FC value in all datasets were chosen. Additionally, genes with a significant enrichment value in at least five datasets and either median log2FC > 1 or mean log2FC > 1 or a positive log2FC value in all datasets were chosen as well.
This initial unbiased set of genes was then manually refined by (1) excluding genes encoded by the mitochondrial genome as well as some genes with the annotated nuclear or mitochondrial function (Pola1, Ezh2, Smc4, Cenpb, Pink1 and Ncl); (2) adding genes with a known zipcode or neurite localization sequence (Camk2a94 (link), Actb5 (link), Bdnf9 (link), Arc11 (link),95 (link), Cdc42 (ref. 25 (link)), Map2 (ref. 96 (link)) and Bc1 (ref. 97 (link)); (3) adding genes that showed localization in non-primary31 (link) and in-house datasets as well as our PCN and fewer other primary datasets (Rab13, Net1, Hmgn5, 2410006H16Rik, Pfdn5, Tagln2, Pfdn1 and Cryab); and (4) restricting the genes encoding for ribosomal proteins and translation factors to a smaller subset with sufficiently large 3′ UTRs (Rplp2, Rpl12, Rpl39, Rpl37, Rpl14, Rps28, Rpsa, Rps24, Rps23, Rps18, Eef1b2, Eef1a1 and Eef1g).

The study was cross-sectional and prospective in design. It was carried out between 2012 and 2020 within the population of outpatients and inpatients of the Department of Rheumatology and Internal Medicine in Poznan, Poland. The study population consisted of 96 adult patients with SSc, classified using the American College of Rheumatology and the European League Against Rheumatism (ACR-EULAR) 2013 criteria [12 (link)]. There were no exclusion criteria.
History taking and physical examination of all patients were carried out by the same physician (P.Ż.), who has experience in the care of SSc patients. Clinical data were collected using MEDS (Minimal Essential Data Set) in line with the EUSTAR (EULAR Scleroderma Trials and Research group) methodology [13 (link)], also by the same practitioner. The following features were assessed: gender, age, time of disease since the onset of Raynaud’s phenomenon, time of disease since the onset of other symptoms characteristic of SSc, duration of the disease since the diagnosis, skin involvement using the modified Rodnan skin score (mRSS), Raynaud’s phenomenon, digital ulcerations, synovitis, joint contractures, muscle weakness, esophageal symptoms (heartburn and dysphagia), intestinal manifestations (diarrhea, constipation, and bloating), arterial hypertension, scleroderma renal crisis (ever), dyspnea, and palpitations.
Specialist cardiac (echocardiography) and pulmonary examination (pulmonary function tests and high-resolution computed tomography) were carried out. Certified specialist physicians interpreted the results: a cardiologist (T.M.-K.) and a pulmonologist (T.P.), both with considerable experience in SSc diagnostics. A number of characteristics were sought: heart conduction blocks; palpitations, systolic and diastolic dysfunction; ejection fraction; pulmonary arterial hypertension using Doppler ultrasonography; total lung capacity; pulmonary restriction using pulmonary function tests; and the presence of SSc-related interstitial lung disease (ILD) using HRCT.
Sera of patients were secured and assessed for autoantibodies. An immunoblot test known as Systemic Sclerosis Profile (SSP) by EUROIMMUN Medizinische Labordiagnostika AG (Lübeck, Germany) was used to assess SSc-related autoantibodies (Scl-70, centromere protein A, centromere protein B, RNA Pol III 11 kDa, RNA Pol III 155 kDa, fibrillarin, Nor90, Th/To, PM-Scl100, PM-Scl75, Ku, PDGFR, and Ro-52) according to the manufacturer’s recommendations, including the cutoff for seropositivity. Similarly, we used an ANA profile immunoblot by the same manufacturer to detect Scl-70, CENP-B, and PM-Scl. In addition, we determined the erythrocyte sedimentation rate (ESR), C-reactive protein concentration, serum creatinine concentration, the estimated glomerular filtration rate (chronic kidney disease epidemiology collaboration equation; eGFR CKD), as well as the presence or absence of proteinuria.
Statistical analyses were conducted in Statistica 13.3 (TIBCO, Palo Alto, CA, USA) and Microsoft Excel 2016 (Redmond, WA, USA). The associations between autoantibody seropositivity and clinical manifestations or disease subset were assessed using Fisher’s exact test, whereas the comparison of the sensitivity of both immunoblots was made using McNemar’s chi-square test. The significance threshold was set at 0.05. In cases where the contingency table included at least one zero while calculating odds ratios, we used Haldane–Anscombe correction by adding 0.5 to all values in a table so that calculating OR was mathematically possible. Heatmap was created in R 4.1.3 (R Software Foundation, Vienna, Austria) using the pheatmap package 1.0.12, with default hierarchical clustering, after logarithmic transformation (base 10) of odds ratios.
This study obtained the approval of the Bioethics Committee at the Poznan University of Medical Sciences (No. 988/11). All patients participating in the study gave informed consent in writing in line with local law regulations.
