In closed communities such as the Amish in North America, rare genetic disorders occur more frequently. In children from this community, a condition has been described that affects the development of the nervous system and manifests, for example, as muscle weakness or epileptic seizures. The disorder is linked to a small change in a single protein, but for a long time it was unclear which cellular process this change disrupts. This question has now been answered by researchers from CEITEC Masaryk University, who show that the disease is caused by a disruption of a key mechanism required for the proper processing of genetic information in the cell.Every cell must first transcribe genetic information and then modify it before it can be used. From the original “working transcript,” unnecessary parts are removed and the remaining pieces are precisely joined together. This process, known as RNA splicing, consists of many consecutive steps and is tightly regulated. If the process does not proceed correctly or stops at any point, the cell cannot properly convert the copied genetic information into a usable form and therefore cannot function as it should.Researchers from CEITEC Masaryk University have now described one of the key steps in this process – a specific signal inside the cell. This signal acts as a checkpoint: only once it is fulfilled, the entire mechanism is activated and the process can continue.“We showed that during RNA splicing, a chemical modification of the protein SF3B1 is required at a precisely timed step. This modification allows another protein, SNIP1, to bind. If this signal is not transmitted correctly, the cell cannot proceed with the splicing process,” explains first author <a target="_blank" rel="noopener noreferrer" href="https://www.ceitec.eu/pavla-gajduskova-ph-d/u26136?page=publication">Pavla Gajdušková</a>.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Vzacna_geneticka_porucha_z_amisske_komunity_pomohla_potvrdit_klicovy_mechanismus_v_bunce_4_79e003984a.jpeg" alt="CEITEC: A Rare Genetic Disorder in the Amish Community Helped Confirm a Key Cellular Mechanism: Pavla Gajdušková" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Vzacna_geneticka_porucha_z_amisske_komunity_pomohla_potvrdit_klicovy_mechanismus_v_bunce_4_79e003984a.jpeg 235w," sizes="100vw" width="1600" height="1067">This is where the research connects to patients in the Amish community. In affected children, a small genetic change in the SNIP1 protein disrupts its ability to respond properly to the signal mediated by the modified SF3B1 protein, making RNA splicing less efficient than in healthy individuals. As a result, errors occur during RNA splicing that the cell cannot correct, impairing its function – especially in the nervous system.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Vzacna_geneticka_porucha_z_amisske_komunity_pomohla_potvrdit_klicovy_mechanismus_v_bunce_44a7e2ef17.jpg" alt="CEITEC/Blažek Lab: A Rare Genetic Disorder in the Amish Community Helped Confirm a Key Cellular Mechanism: Interaction between SF3B1 and SNIP1 proteins." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Vzacna_geneticka_porucha_z_amisske_komunity_pomohla_potvrdit_klicovy_mechanismus_v_bunce_44a7e2ef17.jpg 156w," sizes="100vw" width="1600" height="1600"><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Vzacna_geneticka_porucha_z_amisske_komunity_pomohla_potvrdit_klicovy_mechanismus_v_bunce_2_85826d711e.jpg" alt="CEITEC/Blažek Lab: A Rare Genetic Disorder in the Amish Community Helped Confirm a Key Cellular Mechanism: The effect of mutations in SNIP1 on cell proliferation." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Vzacna_geneticka_porucha_z_amisske_komunity_pomohla_potvrdit_klicovy_mechanismus_v_bunce_2_85826d711e.jpg 235w," sizes="100vw" width="1600" height="1067">The researchers were thus able to clarify the cause of this rare neurodevelopmental disorder. “Additionally, the cause of this disease also confirms the correctness of the checkpoint we described.

A Rare Genetic Disorder in the Amish Community Helped Confirm a Key Cellular Mechanism

This study investigates the pathogenesis of neurosyphilis through cerebrospinal fluid proteomics using LC–MS/MS and ELISA validation. Comparative analysis identified 234 differentially expressed proteins, with major alterations linked to lysosomal dysfunction, axon guidance, and neurodegeneration pathways.Key lysosomal proteins, including PSAP and DNASE2, together with the axonal protein EPHA4, were significantly downregulated in neurosyphilis patients. These proteins showed potential as biomarkers for neurodegeneration and may provide new insights into disease mechanisms, diagnostics, and therapeutic targets.<blockquote><h4>The original article</h4><h4><a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/10.1021/acs.jproteome.5c00689">Cerebrospinal Fluid Proteome Reveals Dysregulation of Lysosomal and Axonal Proteins in Neurosyphilis</a></h4>Huayang Tang*, Junjie Hu, Yifan Wu, Jinping Gao, Wenjun Wang, Xiaodong Zheng, Ran Zhang, Bo Liang, Fusheng Zhou, Ze Guo*J.

Validation was then performed by ELISA in an independent group comprising 110 samples. The results revealed that neuroinflammation by T. pallidum infection results in dysregulation of the key proteins in lysosomal and axonal pathway, which suggesting a potential contribution to neurodegeneration in neurosyphilis.<h4>Materials and Methods</h4><h5>LC–MS/MS</h5>The tryptic peptides were dissolved in 0.1% formic acid (solvent A) and loaded onto a custom-made reversed-phase column (15 cm × 75 μm). Using an EASY-nLC 1000 UPLC system, a gradient was run at 400 nL/min as follows: 6% to 23% solvent B (0.1% formic acid in 98% acetonitrile) over 26 min, 23% to 35% in 8 min, up to 80% in 3 min, and held at 80% for 3 min. Peptides were ionized via an NSI source at 2.0 kV and analyzed online by a <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/559">Q Exactive Plus mass spectrometer</a>. Full scans (m/z 350–1800) were acquired in the Orbitrap at 70,000 resolution. The top precursors were selected for MS/MS with an NCE of 28, and fragments were detected at 17,500 resolution. A data-dependent method cycled between one MS scan and 20 MS/MS scans with a 15.0 s dynamic exclusion. AGC was set at 5E4. MS/MS data were processed with MaxQuant (v.1.5.2.8) using Trypsin/P as the enzyme (up to 2 missed cleavages). Precursor mass tolerance was 20 ppm (first search) and 5 ppm (main search); fragment mass tolerance was 0.02 Da. Fixed modification: carbamidomethyl (C); variable modification: oxidation (M). The FDR threshold was &lt;1%, and the minimum peptide score was &gt;40.<h5>ELISA</h5>CSF levels of host proteins were quantified using commercial ELISA kits according to the manufacturers’ protocols. Proteins analyzed included PSAP (OKEH07124, Aviva, USA), CTSL (abx150963, Abbexa, UK), NPC2 (A-QEK07857, Biogradetech, USA), and DNASE2 (abx386953, Abbexa, UK). Briefly, 100 μL of CSF was added to precoated plates and incubated at 37 °C for 2 h. After washing, 100 μL of detection antibody was added to each well and incubated at 37 °C for another 2 h. Following a wash, 100 μL of streptavidin-HRP working solution was added and incubated at room temperature for 20 min in the dark. The reaction was stopped with 50 μL of stop solution, and the optical density was measured at 450 nm.<h4>Results</h4><h5>Downregulation of Key Lysosomal Proteins in CSF from Patients With Neurosyphilis</h5>By analyzing the DEPs in NS vs nNS, we observed a significant enrichment of downregulated proteins in the lysosome pathway (P = 0.007) (<a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/10.1021/acs.jproteome.5c00689#fig2">Figure 2</a>A), with 9 lysosomal proteins showing significant downregulation (Padj &lt; 0.05) in the NS group (<a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/suppl/10.1021/acs.jproteome.5c00689/suppl_file/pr5c00689_si_001.zip">Table S4</a>).

First, the use of ELISA to validate a limited number of proteins has certain limitations, such as the inherent cross-reactivity of ELISA. In the future, we can optimize the validation experiments by adding techniques such as Western blotting for verification. Second, this study uses a cross-sectional sampling method for research, which limits our ability to infer disease progression and treatment responses. In the future, we will conduct follow-up on the subjects, continue collecting cerebrospinal fluid samples after treatment, and observe whether the protein dysregulation is reversible after treatment. For spNS patients, follow-up should also be conducted to determine if they have transformed into NS, which will be very valuable for validating the predictive utility of our biomarkers. Finally, although multiple discovery and validation cohort studies have been conducted, we currently lack direct mechanistic evidence. Future work will investigate whether exposing neural cell coculture models to outer-membrane antigens of T. pallidum reproduces the lysosome and axon alterations observed in CSF, clarifying their role in neural damage of neurosyphilis and potential biomarkers for diagnosis and treatment of neurodegeneration in neurosyphilis.</div>

Watrex SPR-200 Solvent saver

Watrex SPR-200 Solvent Recycler is designed to save up to 90% of mobile phase during isocratic HPLC.

This Solvent Recycler saves up to 90% of mobile phase by redirection of the pure solvent to the solvent reservoir during the isocratic HPLC. The stand alone device is powered by 5 V DC from power adapter or from computer USB port. Working parameters (Threshold and Delay) are easily set on the display using a membrane keyboard.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Watrex_Watrex_SPR_200_Solvent_saver_I_Nputs_694d991f2c.jpg" alt="Watrex: Watrex SPR-200 Solvent saver - INputs">The SPR-220™ Solvent Recycler continuously monitors the output signal of the chromatography detector and displays its current value on the built-in display. A highresolution analog-to-digital converter provides data for further evaluation in the built-in processor. If the input signal level exceeds a preset value (Threshold), the SPR-200 will redirect the flow to the waste.When the signal drops, the solvent recycler waits for the transport delay and then switches the mobile phase back to the reservoir. An autosampler injection marker connected to the SPR-200 ZERO input can be used to zero the input signal at the time of injection.<h3>FEATURES</h3><ul><li>Stand alone operation</li><li>Detachable valve</li><li>Possibility of manual Waste/Recycle switching</li></ul><h3>TECHNICAL SPECIFICATION</h3><ul><li>Detector compatibility: compatible with any HPLC detector</li><li>Connection: 1/16″ O.D. tubing, 1/4″-28 flat bottom fittings</li><li>Maximum pressure: 30 p.s.i./0,2 MPa</li><li>Wetted material: PEEK, PTFE</li><li>Input range: +/- 1 V or +/- 100 mV, user selectable</li><li>Computer connection: μUSB</li><li>TTL/contact closure input: configurable (ZERO, start, valve position)</li><li>Power: 5V DC/&lt;100 mA (power supply or computer USB port)</li><li>User interface: large character LCD alphanumeric display + membrane keypad</li></ul><h3>Ordering information:</h3><h5>PN/Component:</h5><ul><li>SPR200-001 SPR-200 Solvent Recycler, PEEK version (Price 1 250 € ex VAT)</li><li>SPR200-002 SPR-200 Solvent Recycler, PTFE version (Price 1 250 € ex VAT)</li></ul>You can also visit this product on the <a target="_blank" rel="noopener noreferrer" href="https://watrex.com/?s=SPR-200+Solvent&amp;post_type=product&amp;dgwt_wcas=1?utm_source=labrulez&amp;utm_medium=propagace&amp;utm_campaign=labrulez_produkty">Watrex website</a>.
