A novel and ubiquitous miRNA-involved regulatory module ensures precise phosphorylation of RNA polymerase II and proper transcription.

Proper transcription orchestrated by RNA polymerase II (RNPII) is crucial for cellular development, which is rely on the phosphorylation state of RNPII's carboxyl-terminal domain (CTD). Sporangia, developed from mycelia, are essential for the destructive oomycetes Phytophthora, remarkable transcriptional changes are observed during the morphological transition. However, how these changes are rapidly triggered and their relationship with the versatile RNPII-CTD phosphorylation remain enigmatic. Herein, we found that Phytophthora capsici undergone an elevation of Ser5-phosphorylation in its uncanonical heptapeptide repeats of RNPII-CTD during sporangia development, which subsequently changed the chromosomal occupation of RNPII and primarily activated transcription of certain genes. A cyclin-dependent kinase, PcCDK7, was highly induced and phosphorylated RNPII-CTD during this morphological transition. Mechanistically, a novel DCL1-dependent microRNA, pcamiR1, was found to be a feedback modulator for the precise phosphorylation of RNPII-CTD by complexing with PcAGO1 and regulating the accumulation of PcCDK7. Moreover, this study revealed that the pcamiR1-CDK7-RNPII regulatory module is evolutionarily conserved and the impairment of the balance between pcamiR1 and PcCDK7 could efficiently reduce growth and virulence of P. capsici. Collectively, this study uncovers a novel and evolutionary conserved mechanism of transcription regulation which could facilitate correct development and identifies pcamiR1 as a promising target for disease control.

Normal table of embryonic development in the Anji salamander Hynobius amjiensis (Hynobiidae).

We established a normal embryonic development table for the Anji salamander Hynobius amjiensis, a critically endangered tailed amphibian of the family Hynobiidae with a very limited distribution in East China, following the standards set by the early developmental table of vertebrates. Put together 32 embryonic stages for the Anji salamander was defined. The total embryonic period from oviposition to hatching is approximately 30 days at 9 °C. Stages 1-16 represent early development from cleavage to neurulation. Stages 17-32 represent organogenesis documenting later developmental events such as tail, gill, and limb formation, and hatching (Stage 32). We provided a detailed description of the external morphology and color changes of the head, trunk, limbs, tail, external gills, and balancers at various stages from egg-laying to hatching. We also described several cases of abnormal embryonic development. The establishment of the embryonic development table in H. amjiensis contributes to better understanding of the ontogeny in tailed amphibians, distinguishing closely related species, and identifying abnormal embryonic amphibians.

Boosting Zinc Storage Performance of Li3 VO4 Cathode Material for Aqueous Zinc Ion Batteries via Carbon-Incorporation: A Study Combining Theory and Experiment.

In the search for sustainable cathode materials for aqueous zinc ion batteries (AZIBs), vanadium (V)-based materials have garnered interest, primarily due to their abundance and multiple oxidation states. Among the contenders, Li3 VO4 (LiVO) stands out for its affordability, high specific capacity, and elevated ionic conductivity. However, its limited electrical conductivity results in significant resistance polarization, limiting its rate capability, especially under high currents. Through density functional theory (DFT) calculations, this study evaluates the electrochemical implications of carbon (C) incorporation within the LiVO matrix. The findings indicate that C integration significantly ameliorates the conductivity of LiVO. Moreover, C serves as a barrier, mitigating direct interactions between Zn2+ and LiVO, which in turn expedites Zn2+ diffusion. When considering various C materials for this role, glucose is emerged as the optimal candidate. The LiVO/C-glucose composite (LiVO/C-G) is observed to undergo dual phase transitions during charge-discharge cycles, resulting in an amorphous vanadium-oxygen (VO) derivative, paving the way for subsequent electrochemical reactions. Collectively, the insights pave a promising avenue for refining AZIB cathode design and performance.

A CD6 homolog of Nile tilapia (Oreochromis niloticus) conserved binding bacteria involved in the regulation of Streptococcus agalactiae induced inflammation.

As a lymphocyte-specific surface receptor belonging to the cysteine-rich superfamily of scavenger receptors, CD6 acts as a pattern recognition receptor for microbial components and is involved in the regulation of inflammatory responses. However, the characteristics and functions of CD6 molecules in lower vertebrates represented by teleost fish are unknown. In this study, a CD6 homolog (designated OnCD6) was characterized from Nile tilapia (Oreochromis niloticus), and establishing its role as a PRRs that participates in immune recognition. OnCD6 contains an open reading frame of 1872 bp that encodes a peptide of 623 amino acids, and contains two conserved SR domain. Multiple sequence alignment revealed that OnCD6 shares a relatively high level of identity with those of other species. Transcriptional expression analysis revealed that OnCD6 was constitutively expressed in immunes tissues such as head kidney and thymus. The expression level of OnCD6 in mainly immune tissues were found significantly upregulated after the injection of Streptococcus agalactiae (S. agalactiae). Moreover, OnCD6 protein was located in the head kidney and brain, mainly over the plasma membrane of lymphocytes in these immune tissues. In vitro experiments showed that CD6 extracellular protein bound to and aggregated several Gram-positive and -negative bacterial strains through the recognition of bacterial surface conserved components LPS and LTA etc. In vivo experiments demonstrated that overexpression OnCD6 before S. agalactiae challenge significantly improved tilapia survival, and this was concomitant with reduced bacterial load and pro-inflammatory cytokines (IL-1ß and TNF-α). Taken together, our results illustrated the function of CD6 molecular pattern recognition receptors (PRRs) is conserved and plays an important role in antibacterial infection.

Response signatures of intestinal microbiota and gene transcription of the pearl gentian grouper to Vibrio harveyi infection.

Vibrio harveyi causes high mortality and severely limits grouper culture. The gut microbiota is an important biological barrier against pathogen invasion. In this study, we investigated dynamic changes in the intestinal microbial community, gene transcription and immune responses signatures of pearl gentian grouper (Epinephelus fuscoguttatus♂ × Epinephelus lanceolatus♀) at 0, 3 and 7 days (referred to as d0, d3 and d7 groups, respectively) after infection with V. harveyi. The results demonstrated that the d7 treatment reduced the gut microbial diversity and increased the proportion of Proteobacteria and Cyanobacteria. Notably, several putative pathogenic genera (Sphingomonas and Bacteroides) proliferated, while putative probiotic genera (Rhodococcus and Lactobacillus) reduced, and these changes in intestinal bacteria might be correlated to the alterations of host immune-related molecules. The d3 and d7 treatments also altered the histomorphology and gene transcription profiles mainly associated with immune function in intestine, such as 'MAPK signaling pathway', 'Apoptosis' and 'Toll-like receptor (TLR) signaling pathway'. Furthermore, d3 group induced a homeostatic dysregulation of the antioxidant system, cytokines and TLR signaling, with a tendency to gradually return to a normal state in d7 group, along with the apoptosis process. The pathogenic infection suppressed the expression of JNK pathway and enhanced the ERK pathway. In conclusion, the dysbiosis of the intestinal bacterial communities caused by the immune changes that occurred during V. harveyi infection disrupted the intestine health in the pearl gentian grouper. These results provided a comprehensive understandings of the immune defense mechanisms in fish and valuable references to develop disease control strategies in grouper aquaculture.

Current Understanding of Timing of Surgical Repair for Ventricular Septal Rupture following Acute Myocardial Infarction.

BACKGROUND: Ventricular septal rupture (VSR) is a mechanical issue that can occur following an acute myocardial infarction (AMI) and has a high mortality rate. It requires a comprehensive, team-based approach for prompt diagnosis and maintaining stable blood flow. While the occurrence of VSR has lessened over the past hundred years and advancements have been made in treatment techniques, the mortality rate within 30 days can still surpass 40 percent. Surgery is the primary treatment method. For patients with stable blood flow, it is generally considered safer to perform surgery 4-6 weeks after the AMI to repair the VSR. However, the timing of surgery for patients with early instability in their blood flow is still a topic of debate. SUMMARY: There is a lack of set criteria and standards to determine the best time for surgery in patients with VSR following an infarction who have unstable blood flow, especially when considering the use of blood circulation support devices and other techniques for maintaining blood flow that are used in clinical settings. KEY MESSAGES: This review outlines the features of different mechanical circulatory support devices utilized in treating VSR, along with the current scoring system designed to direct the treatment approach for VSR patients.

von Hippel-Lindau-targeting microRNA-143-3p attenuates mitochondrial abnormality via AMPK/PGC-1α axis in Parkinson's disease.

Parkinson's disease (PD) is the second most common neurodegenerative disease characterized by selective loss of dopaminergic neurons. We previously found that inhibition of von Hippel-Lindau (VHL) can alleviate dopaminergic neuron degeneration in PD models via regulation of mitochondrial homeostasis, however, the disease-related alterations of VHL and the regulatory mechanisms of VHL level in PD need to be further investigated. In this study, we found that the levels of VHL were markedly increased in multiple cell models of PD and identified microRNA-143-3p (miR-143-3p) as a promising candidate for regulating VHL expression involved in PD. miR-143-3p directly bound to the 3'untranslated region of human VHL mRNA and inhibited its translation, and exerted neuroprotective effects by improving cell viability, apoptosis and tyrosine hydroxylase abnormality. Furthermore, we demonstrated that miR-143-3p exerted neuroprotection by attenuating mitochondrial abnormality via AMP-activated protein kinase (AMPK)/peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) axis, and AMPK inhibitor abolished the beneficial effects of miR-143-3p on the cell model of PD. Therefore, we identify the dysregulated VHL and miR-143-3p in PD, and propose the therapeutic potential of miR-143-3p to alleviate PD by improving mitochondrial homeostasis via AMPK/PGC-1α axis.

Beyond silence: evolving ultrasound strategies in the battle against cardiovascular thrombotic challenges.

Cardiovascular thrombotic events have long been a perplexing factor in clinical settings, influencing patient prognoses significantly. Ultrasound-mediated acoustic therapy, an innovative thrombolytic treatment method known for its high efficiency, non-invasiveness, safety, and convenience, has demonstrated promising potential for clinical applications and has gradually become a focal point in cardiovascular thrombotic disease research. The current challenge lies in the technical complexities of preparing ultrasound-responsive carriers with thrombus-targeting capabilities and high thrombolytic efficiency. Additionally, optimizing the corresponding acoustic treatment mode is crucial to markedly enhance the thrombolytic effectiveness of ultrasound-mediated acoustic therapy. In light of the current status, this article provides a comprehensive review of the research progress in innovative ultrasound-mediated acoustic therapy for cardiovascular thrombotic diseases. It explores the impact of technical methods, therapeutic mechanisms, and influencing factors on the thrombolytic efficiency and clinical potential of ultrasound-mediated acoustic therapy. The review places particular emphasis on identifying solutions and key considerations in addressing the challenges associated with this cutting-edge therapeutic approach.

Dual-mode nanoprobe strategy integrating ultrasound and near-infrared light for targeted and synergistic arterial thrombolysis.

Efficient thrombolysis in time is crucial for prognostic improvement of patients with acute arterial thromboembolic disease, while limitations and complications still exist in conventional thrombolytic treatment methods. Herein, our study sought to investigate a novel dual-mode strategy that integrated ultrasound (US) and near-infrared light (NIR) with establishment of hollow mesoporous silica nanoprobe (HMSN) which contains Arginine-glycine-aspartate (RGD) peptide (thrombus targeting), perfluoropentane (PFP) (thrombolysis with phase-change and stable cavitation) and indocyanine green (ICG) (thrombolysis with photothermal conversion). HMSN is used as the carrier, the surface is coupled with targeted RGD to achieve high targeting and permeability of thrombus, PFP and ICG are loaded to achieve the collaborative diagnosis and treatment of thrombus by US and NIR, so as to provide a new strategy for the integration of diagnosis and treatment of arterial thrombus. From the in vitro and in vivo evaluation, RGD/ICG/PFP@HMSN can aggregate and penetrate at the site of thrombus, and finally establish the dual-mode directional development and thrombolytic treatment under the synergistic effect of US and NIR, providing strong technical support for the accurate diagnosis and treatment of arterial thrombosis.

Construction of a predictive model for new-onset atrial fibrillation after acute myocardial infarction based on P-wave amplitude in lead V1.

BACKGROUND: In this study, we aimed to identify the risk factors for new-onset atrial fibrillation (NOAF) after postcoronary intervention in patients with acute myocardial infarction (AMI) and to establish a nomogram prediction model. METHODS: The clinical data of 506 patients hospitalized for AMI from March 2020 to February 2023 were retrospectively collected, and the patients were randomized into a training cohort (70%; n = 354) and a validation cohort (30%; n = 152). Independent risk factors were determined using least absolute shrinkage and selection operator and multivariate logistic regression. Predictive nomogram modeling was performed using R software. Nomograms were evaluated based on discrimination, correction, and clinical efficacy using the C-statistic, calibration plot, and decision curve analysis, respectively. RESULTS: The multivariate logistic regression analysis showed that P-wave amplitude in lead V1, age, and infarct type were independent risk factors for NOAF, and the area under the receiver operating characteristic curve of the training and validation sets was 0.760 (95% confidence interval [CI] 0.674-0.846) and 0.732 (95% CI 0.580-0.883), respectively. The calibration curves showed good agreement between the predicted and observed values in both the training and validation sets, supporting that the actual predictive power was close to the ideal predictive power. CONCLUSIONS: P-wave amplitude in lead V1, age, and infarct type were independent risk factors for NOAF in patients with AMI after intervention. The nomogram model constructed in this study can be used to assess the risk of NOAF development and has some clinical application value.

Latent profile analysis of successful aging among empty nesters in Guiyang, China.

OBJECTIVES: To explore potential profiles of successful aging among empty nesters using latent profile analysis and to analyze their influencing factors. METHODS: A total of 452 community-based empty nesters were included using convenience sampling. Empty nesters were surveyed using the Successful Ageing Scale, Social Capital Scale, Sense of Coherence Scale, and Chinese version of the Health-Promotion Lifestyle Scale-II. Latent profile analysis was used to categorize the successful aging of empty nesters, and factors influencing each category were analyzed using multiple logistic regression. RESULTS: Four latent profiles of successful aging were identified: 'low successful aging-low spirituality', 'high successful aging-spiritual fluctuation', 'high successful aging-balanced development group', and 'medium successful aging-medium spirituality'. The results of the multiple logistic regression analysis showed that gender, education, residence mode, and social capital were factors influencing the potential profiles of successful aging. CONCLUSIONS: There are four potential categories of successful aging among empty nesters. Gender, education, residence mode, and social capital were associated with successful aging among empty nesters. Targeting interventions may help enhance empty nesters' successful aging. Future research should combine subjective and objective indicators to assess the health of older people and explore other determinants for formulating interventions to improve successful aging of empty nesters.

Comparative efficacy of non-pharmacological interventions on sleep quality in old adults: A systematic review and network meta-analysis.

AIMS AND OBJECTIVES: To compare the effectiveness of non-pharmacological interventions in enhancing sleep quality in older people. BACKGROUND: Sleep problems in older adults have become increasingly prominent. Sleep problems not only affect the health and quality of life of older people, but also the range of chronic diseases caused by sleep problems also impose a huge burden on social services and health care. Non-pharmacological interventions are an effective alternative to pharmacological therapies, but it is unclear which non-pharmacological therapies are most effective in enhancing sleep quality in older adults. DESIGN: A systematic review and network meta-analysis based on PRISMA-NMA. METHODS: A total of seven databases were searched from the establishment of the database to March 2023. After literature screening and data extraction, the Cochrane Bias assessment tool 2.0 version of randomised controlled trials (RCTs) was used to evaluate literature quality. A network meta-analysis was performed to evaluate the relative efficacy of the non-pharmacological interventions on sleep quality. RESULTS: A total of 71 RCTs involving nine non-pharmacological interventions were included. The results of the network meta-analysis showed that the joint intervention may be the most effective non-pharmacological intervention to enhance sleep quality in older adults. CONCLUSION: This study confirms that non-pharmacological interventions can improve sleep quality in older adults. The use of non-pharmacological interventions can be promoted by healthcare professionals in the future to improve the quality of sleep and thus the physical and mental health of older people. RELEVANCE TO CLINICAL PRACTICE: This evidence suggests that joint interventions may be most effective. Therefore, in the future, a combination of non-pharmacological interventions could be used to maximise their effectiveness in improving sleep quality in older people and promoting healthy aging. NO PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution is not applicable to this study.

Tracheostomy care of non-ventilated patients and COVID considerations: A scoping review of clinical practice guidelines and consensus statements.

BACKGROUND: The purpose of this study is to examine and evaluate the existing clinical practice guidelines and consensus statements regarding tracheostomy care for non-mechanically ventilated patients. METHODS: A systematic search of databases, and professional organisations was conducted from inception to 19 March 2023. Two appraisers evaluated each guideline using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) and the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Text and Opinion Papers. RESULTS: No specific clinical guidelines exist on airway management in non-mechanically ventilated patients. Of 6318 articles identified, we included 12 clinical practice guidelines, and 9 consensus statements, which were from China, the US, the UK, South Korea, Australia, France and Belgium. The AGREE II scores in six domains are (1) the scope and purpose, 70.30%; (2) stakeholder involvement, 37.61%; (3) rigor of development, 33.97%; (4) clarity of presentation, 68.16%; (5) applicability, 44.23% and (6) editorial independence, 40.06%. The overall quality of evidence was level B. The summarised recommendations for clinical practice encompass the following six areas: airway humidification, management of the trach cuff, management of inner cannula, tracheostoma care, tracheostomy suctioning and management and prevention of common post-operative complications. CONCLUSIONS: The overall quality of the clinical guidelines on non-ventilated tracheostomy care was moderate, and further improvements are needed in domains of stakeholder involvement, applicability, clarity of presentation and editorial independence. Recommendations on non-ventilated tracheostomy care are often embedded in the guidelines on ventilated tracheostomy. Specific clinical guidelines are needed to provide a standardised approach to tracheostomy care for non-ventilated patients. RELEVANCE TO CLINICAL PRACTICE: Patients with non-ventilated tracheostomy need specialised airway management. Improving patient outcomes requires standardised protocols, patient involvement, quality evaluation, and interdisciplinary approaches. NO PATIENT OR PUBLIC CONTRIBUTION: The study reviewed clinical practice guidelines and consensus statements, therefore patient or public input was not needed.

Comparative effectiveness of eHealth interventions on the exercise endurance and quality of life of patients with COPD: A systematic review and network meta-analysis.

AIMS: To compare the effectiveness of different types of eHealth interventions in improving exercise endurance and quality of life in chronic obstructive pulmonary disease (COPD) patients. BACKGROUND: COPD is a chronic airway disease characterized by persistent respiratory symptoms and airflow limitation. eHealth interventions have been accepted and recognized by healthcare professionals and COPD patients as an effective alternative to pulmonary rehabilitation. However, it is not clear which eHealth interventions are effective and preferred for exercise endurance and quality of life in COPD patients. DESIGN: A systematic review and network meta-analysis based on PRISMA-NMA. METHODS: We searched nine electronic databases to identify randomized controlled trials addressing the effect of eHealth interventions on the exercise endurance and quality of life of COPD patients from their inception to 30 October 2022. First, a random-effects model was chosen to conduct a traditional meta-analysis to directly investigate the efficacy of different eHealth interventions. Next, a network meta-analysis was performed to evaluate the relative efficacy of the eHealth interventions for COPD. The quality of the data was assessed using the Cochrane Risk of Bias tool. RESULTS: Fifty-one studies containing six eHealth interventions (telemonitoring, application [APP], web-based interventions, phone calls, virtual reality and combined interventions [≥two types]) were included in the final analysis. Network meta-analysis showed that telemonitoring, APP, web-based interventions and combined interventions improved exercise endurance in COPD patients, with telemonitoring being the most effective. Web-based interventions and apps are effective in improving the quality of life, and web-based interventions are the most effective. CONCLUSIONS: This study confirms that eHealth interventions can improve exercise endurance and quality of life in COPD patients. In the future, healthcare professionals can promote the use of telemedicine in COPD patients to enhance their exercise endurance and quality of life according to their individual needs. RELEVANCE TO CLINICAL PRACTICE: This evidence suggests that eHealth interventions can improve exercise endurance and quality of life in COPD patients. Therefore, in the future, eHealth interventions could be used to maximize their effectiveness in improving exercise endurance and quality of life in COPD patients.

Non-pharmacological interventions for preventing emergence delirium in children under general anesthesia: A scoping review.

PROBLEM: The phenomenon of emergence delirium in pediatric patients undergoing general anesthesia has garnered increasing attention in the academic community. While formal non-pharmaceutical interventions have demonstrated efficacy in mitigating this phenomenon, the diversity of intervention types and their varying degrees of effectiveness necessitate further discussion. A scoping review was conducted to identify and explicate the categorization, content elements, and outcomes measures of non-pharmacological interventions utilized to forestall the onset of emergence delirium in children undergoing general anesthesia. ELIGIBILITY CRITERIA: This review was conducted in accordance with the Arksey and O'Malley's methodology framework and PRISMA-ScR. It encompassed experimental and quasi-experimental studies that involved any non-pharmacological interventions during the perioperative period to prevent emergence delirium in children aged 0 to 18 years undergoing general anesthesia for elective surgery. SAMPLE: Thirty-two articles met the inclusion criteria, of which 29 were randomized controlled trials. The total sample size of the population was 4633. RESULTS: The scoping review revealed 10 non-pharmacological interventions, that included distraction intervention, visual preconditioning, virtual reality, parental participation, maternal voice, light drinking, acupuncture, auditory stimulation, monochromic light and breathing training. Emergence delirium, preoperative anxiety, and postoperative pain were the primary outcomes, and four assessment instruments were employed to measure the extent and incidence of emergence delirium. CONCLUSION: Numerous non-pharmacological interventions have been employed to prevent emergence delirium. Nevertheless, the effectiveness of some interventions is not yet evident. IMPLICATIONS: The utilization of visual preconditioning and distraction interventions appears to be an emerging area of interest.

The Experiences and Perceptions of Older Adults with Multimorbidity Toward E-Health Care: A Qualitative Evidence Synthesis.

Background: Given the growing population of older adults globally, e-Health plays an indispensable role in the chronic disease management of multimorbidity. However, qualitative evidence that synthesizes the experiences of older adults with multimorbidity using e-Health service is currently lacking. The objective was to explore the experiences and perceptions of e-Health care in community-based settings among the older adults with multimorbidity. Methods: Seven electronic databases including PubMed, The Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Embase, Web of Science, China National Knowledge Infrastructure, and Chinese BioMedical Literature were searched, and the search was limited to studies from inception to September 1, 2023. Screening, data extraction, and quality appraisal were conducted independently by two reviewers. Thomas and Harden's thematic synthesis methodology was applied to synthesize the original themes. The methodological quality of included studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research, and the confidence of synthesized themes was evaluated by the Confidence in the Evidence from Reviews of Qualitative Research approaches. Results: Ten studies with moderate methodological quality met eligibility criteria and were included finally. Studies were conducted in four countries with 235 participants who were living with multiple chronic conditions. Among the 10 included studies, 37 credible findings were extracted and interpreted into 3 synthesized themes and 12 subthemes: (1) advantages and benefits perceived during e-Health service, (2) multidimensional challenges and negative experience posed by e-Health service, and (3) preferences, suggestions, and expectations for future e-Health improvement. The confidence in the majority of the three final synthesized themes was rated between "low" and "moderate" scales. Conclusions: The findings of this study provide new insights into implementing tailored e-Health care for older adults with multimorbidity. Further research should emphasize on realizing the potential value of e-Health service based on users' needs and perspectives to promote age-friendliness in geriatric practice.

DeepSub: Utilizing Deep Learning for Predicting the Number of Subunits in Homo-Oligomeric Protein Complexes.

The molecular weight (MW) of an enzyme is a critical parameter in enzyme-constrained models (ecModels). It is determined by two factors: the presence of subunits and the abundance of each subunit. Although the number of subunits (NS) can potentially be obtained from UniProt, this information is not readily available for most proteins. In this study, we addressed this gap by extracting and curating subunit information from the UniProt database to establish a robust benchmark dataset. Subsequently, we propose a novel model named DeepSub, which leverages the protein language model and Bi-directional Gated Recurrent Unit (GRU), to predict NS in homo-oligomers solely based on protein sequences. DeepSub demonstrates remarkable accuracy, achieving an accuracy rate as high as 0.967, surpassing the performance of QUEEN. To validate the effectiveness of DeepSub, we performed predictions for protein homo-oligomers that have been reported in the literature but are not documented in the UniProt database. Examples include homoserine dehydrogenase from Corynebacterium glutamicum, Matrilin-4 from Mus musculus and Homo sapiens, and the Multimerins protein family from M. musculus and H. sapiens. The predicted results align closely with the reported findings in the literature, underscoring the reliability and utility of DeepSub.
