Aberrant gene activation in synovial sarcoma relies on SSX specificity and increased PRC1.1 stability. Nat Struct Mol Biol 2023; 30:1640-1652.

Abstract
The SS18-SSX fusion drives oncogenic transformation in synovial sarcoma by bridging SS18, a member of the mSWI/SNF (BAF) complex, to Polycomb repressive complex 1 (PRC1) target genes. Here we show that the ability of SS18-SSX to occupy H2AK119ub1-rich regions is an intrinsic property of its SSX C terminus, which can be exploited by fusion to transcriptional regulators beyond SS18. Accordingly, SS18-SSX recruitment occurs in a manner that is independent of the core components and catalytic activity of BAF. Alternative SSX fusions are also recruited to H2AK119ub1-rich chromatin and reproduce the expression signatures of SS18-SSX by engaging with transcriptional activators. Variant Polycomb repressive complex 1.1 (PRC1.1) acts as the main depositor of H2AK119ub1 and is therefore required for SS18-SSX occupancy. Importantly, the SSX C terminus not only depends on H2AK119ub1 for localization, but also further increases it by promoting PRC1.1 complex stability. Consequently, high H2AK119ub1 levels are a feature of murine and human synovial sarcomas. These results uncover a critical role for SSX-C in mediating gene deregulation in synovial sarcoma by providing specificity to chromatin and further enabling oncofusion binding by enhancing PRC1.1 stability and H2AK119ub1 deposition.

Abstract
OBJECTIVES Higher CSBP than brachial SBP in individual patient increases cardiovascular (CV) risk. For follow-up it is important to assess the reproducibility of such measurements. The aim of this study was to assess the reproducibility of these differences, expressed as a CSBP/BrachSBP ratios. SUBJECTS AND METHODS Eighty-three patients on antihypertensive therapy were analysed for the reproducibility of such ratios after time interval of several month up to several years. For CSBP estimation, we used the Arteriograph (Tensiomed Ltd.), based on blood pressure measurements by cuff on oscillometric principle, using pulse wave analysis (PWA) for assessment of CSBP. RESULTS The proportion of patients retained the same characteristics (either higher central or higher peripheral SBP) between the first and second measurement was 71.1 %. The association between 1st and 2nd measurement, was statistically significant, p < 0.001. CONCLUSION In our study, a high proportion (60 %) of treated hypertensive patients had CSBP higher than brachial SBP, which may adversely influence their prognosis. This characteristic is highly reproducible. Taking into the account these differences may increase the exactness of CV risk estimation and may contribute to explanation of residual risk of individual patient (Tab. 3, Fig. 1, Ref. 28).

Abstract
OBJECTIVES Central systolic blood pressure (CSBP) is the pressure in the root of aorta, which directly influences organs such as brain, heart and kidneys and is related to organ damage. Its value increases with the aortic stiffness. The aim of this study was to analyze the relationships of CSBP to aortic stiffness parameters. METHODS Central blood pressure (BP) and related parameters were measured by Arteriograph, working based on oscillometric principle, using pulse wave analysis (PWA) approach. We examined 123 patients (69 females, 54 males) with a primary hypertension. RESULTS Using a linear correlation analysis, we found that CSBP was correlated to aortic pulse wave velocity (PWV), aortic and brachial pulse pressure (PP), aortic augmentation index, return time of reflected pressure wave (RT) and aortic and brachial augmentation indexes. Multivariate analysis defines the aortic pulse pressure (PPao) as the most powerful parameter influencing CSBP. By an individual analysis of BP in each patient separately, we defined two different types of central hemodynamics; those with a higher CSBP than brachial SBP occur in stiffer aorta. CONCLUSION The CSBP increases with aortic PP, the most powerful stiffness parameter of aorta. Higher CSBP than brachial SBP usually accompanies a stiffer aorta (Tab. 5, Ref. 19).

Abstract
OBJECTIVES Medial arterial calcification (MAC) is a nonobstructive condition leading to reduced arterial compliance. The disease most commonly occurs in diabetes mellitus. Decreased ankle-brachial pressure index (ABI) is a well-known marker of increased cardiovascular mortality. However, also the values of ABI above 1.3, typical in MAC, are associated with increased mortality. METHODS By means of Holter ECG monitoring, we investigated 41 patients (25 men, 16 women) with mean age of 59±8 years, suffering of type 2 diabetes mellitus and identified as having MAC, and Holter ECG monitoring with an average duration of recording 22.36 hours, was carried out by GE-Marquette MARS ECG Holter system. RESULTS We found frequent incidence of cardiac arrhythmias and myocardial ischemia in 22 patients (53.7 %). Only 19 patients (46.3 %) had normal Holter ECG recordings. ABI values were significantly higher in patients with abnormal ECG Holter recordings. CONCLUSION Our results confirm the importance of ABI estimation in clinical practice. As the central goal of therapy for patients with myocardial ischemia and/or complex forms of cardiac arrhythmias is the reduction or elimination of these episodes. Ambulatory Holter ECG monitoring plays an important role in the management of these patients (Tab. 7, Ref. 16).

The genomic landscape of human cellular circadian variation points to a novel role for the signalosome. eLife 2017; 6:e24994.

Abstract
The importance of natural gene expression variation for human behavior is undisputed, but its impact on circadian physiology remains mostly unexplored. Using umbilical cord fibroblasts, we have determined by genome-wide association how common genetic variation impacts upon cellular circadian function. Gene set enrichment points to differences in protein catabolism as one major source of clock variation in humans. The two most significant alleles regulated expression of COPS7B, a subunit of the COP9 signalosome. We further show that the signalosome complex is imported into the nucleus in timed fashion to stabilize the essential circadian protein BMAL1, a novel mechanism to oppose its proteasome-mediated degradation. Thus, circadian clock properties depend in part upon a genetically-encoded competition between stabilizing and destabilizing forces, and genetic alterations in these mechanisms provide one explanation for human chronotype.

Abstract
The NONO protein has been characterized as an important transcriptional regulator in diverse cellular contexts. Here we show that loss of NONO function is a likely cause of human intellectual disability and that NONO-deficient mice have cognitive and affective deficits. Correspondingly, we find specific defects at inhibitory synapses, where NONO regulates synaptic transcription and gephyrin scaffold structure. Our data identify NONO as a possible neurodevelopmental disease gene and highlight the key role of the DBHS protein family in functional organization of GABAergic synapses.

Abstract
The electrophoretic separation of lipoproteins on polyacrylamide gels enables the quantification of nonatherogenic and atherogenic plasma lipoproteins including small dense low density lipoprotein (sdLDL) particles, which represent the atherogenic lipoprotein subpopulations in plasma. This methodology could help distinguish between nonatherogenic hyperlipidemia, normolipidemia with an atherogenic lipoprotein profile, non-atherogenic normolipidemia, and atherogenic hyperlipidemia. According to our pilot research of a normolipidemic population, the atherogenic lipoprotein profile might be present in about 6% of normolipidemic young healthy individuals. Therefore, if confirmed by other studies, it will be necessary to consider a different diagnostic approach and risk stratification for patients with atherogenic normolipidemia (as well as non-atherogenic hypercholesterolemia).

Abstract
Circadian clocks are present in most cells and are essential for maintenance of daily rhythms in physiology, mood, and cognition. Thus, not only neurons of the central circadian pacemaker but also many other peripheral tissues possess the same functional and self-sustained circadian clocks. Surprisingly, however, their properties vary widely within the human population. In recent years, this clock variance has been studied extensively both in health and in disease using robust lentivirus-based reporter technologies to probe circadian function in human peripheral cells as proxies for those in neurologically and physiologically relevant but inaccessible tissues. The same procedures can be used to investigate other conserved signal transduction cascades affecting multiple aspects of human physiology, behavior, and disease. Accessing gene expression variation within human populations via these powerful in vitro cell-based technologies could provide important insights into basic phenotypic diversity or to better interpret patterns of gene expression variation in disease.

Abstract
Diabetic nephropathy is becoming an increasingly important cause of morbidity and mortality worldwide as a consequence of increasing prevalence of type 2 diabetes and obesity. The glomeruli of patients with diabetes are characterized by glomerular hypertrophy, widening of the glomerular basement membrane, mesangial expansion, podocytopenia leading to nodular (Kimmelstiel-Wilson) glomerulosclerosis. Many studies have reported the initiation and progression of incipient nephropathy in type 1 diabetes patients, but only limited data are available in type 2 diabetes patients. The information on the risk factors and conversion rate of normal renal function to proteinuria in type 2 diabetes patients is sparse. In this report, we review risk factors of diabetic nephropathy progression in type 2 diabetes patients (Ref. 50).

Abstract
Various lines of evidence suggest a mechanistic role for altered cAMP-CREB (cAMP response element - binding protein) signaling in depressive and affective disorders. However, the establishment and validation of human inter-individual differences in this and other major signaling pathways has proven difficult. Here, we describe a novel lentiviral methodology to investigate signaling variation over long periods of time directly in human primary fibroblasts. On a cellular level, this method showed surprisingly large inter-individual differences in three major signaling pathways in human subjects that nevertheless correlated with cellular measures of genome-wide transcription and drug toxicity. We next validated this method by establishing a likely role for cAMP-mediated signaling in a human neuroendocrine response to light - the light-dependent suppression of the circadian hormone melatonin - that shows wide inter-individual differences of unknown origin in vivo. Finally, we show an overall greater magnitude of cellular CREB signaling in individuals with bipolar disorder, suggesting a possible role for this signaling pathway in susceptibility to mental disease. Overall, our results suggest that genetic differences in major signaling pathways can be reliably detected with sensitive viral-based reporter profiling, and that these differences can be conserved across tissues and be predictive of physiology and disease susceptibility.

Abstract
Intermittent claudication of the lower extremities is a common symptom described in older patients with atherosclerotic peripheral arterial disease. Peripheral arterial disease due to atherosclerosis is known to be associated with a higher risk of myocardial infarction, stroke and all-cause mortality. However, if intermittent claudication appears in a younger group of patients or older patients in absence of traditional risk factors for atherosclerosis such as smoking, dyslipidemia, arterial hypertension and diabetes mellitus other causes than atherosclerosis must be considered. These conditions include vasculitides, fibromuscular dysplasia, cystic adventitial disease, excentric vascular compression by tumor, popliteal artery entrapment syndrome, trauma or dissection. Vasculitides present a heterogenous group of disorders characterized by inflammatory destruction of blood vessels. Although often not a leading symptom intermittent claudication could be a part of a clinical picture in giant-cell arteritis, Takayasu´s arteritis, Buerger´s disease, polyarteritis nodosa or Behçet disease. Limb claudication is usually of rapid onset, progressive and bilateral. Each of the mentioned vasculitides is specific in ethiology and clinical manifestation with a variable prognosis for the patient. Increased awareness of the presence of different causes of limb claudication and their early diagnosis with a prompt initiation of appropriate treatment may help to avoid clinical progression that can lead to vascular surgery or even limb loss (Ref. 37).

Abstract
The aim of our study was to analyse the foot infections in diabetic patients. We analysed foot ulcerations in 124 diabetics who attended outpatient foot clinic, or were hospitalized in the period from 1996 to 2006. Basic neuropathy screening examination was made with cotton wisp, pin-prick, tuning fork, and monofilament. For evaluation of leg ischemia, besides the evaluation of the presence of pedal pulses, the ankle-brachial pressure index was measured. If the infection of foot ulceration was clinically present, bacteriology examinations was performed. In the case of deep wound infection, x-ray examination was made. If bone destruction was present, osteomyelitis was diagnosed by technecium bone scanning and by technecium-labelled leukocyte scan. Deformation and destruction of the bone without infection was appoited as Charcot neuroarthropathy. Foot ulcer infection was found in 58 % diabetic patients, wounds were more often deep (80 %). Infection was not associated with special location of foot ulcer. Two-third of the total infected wounds were associated with leg ischemia and 30.6 % of infected ulcer ended with leg amputation. More foot ulcer infections were found in the diabetics with HbAlc over 8 %. Infection was coupled with diabetic retinopathy (in 63 % patients) (p=0.023), and also with diabetic nephropathy (in 66 % patients) (p=0.012). Bacteriology examination revealed most often Staphylococci (45.8 %), antibiotic therapy was made most often with chinolones. Osteomyelitis was present in 34.7 % of foot ulcer infections. In 14 diabetics (56 %) after antibiotic therapy it was not necessary to perform a leg amputation. HbAlc seems to be a significant predictor of osteomyelitis (p<0.02; OR=1.76). In conclusion, we confirmed that diabetic foot infections, especially on ischemic leg, in diabetics with poor metabolic control and chronic diabetic microvascular complications, are associated with a higher risk of leg amputations. Further, it is possible to cure osteomyelitis successfully without surgery in more than half the cases (Tab. 1, Ref. 24). Full Text in free PDF www.bmj.sk.

The importance of ambulatory blood pressure monitoring (ABPM) in patients with tinnitus. BRATISL MED J 2011; 112:63-66.

Abstract
Arterial hypertension belongs to the most important factors of origin and lasting of tinnitus. We have studied 18 subjects suffering from tinnitus without the history of diagnosed or treated arterial hypertension. ABPM method was used for diagnosing arterial hypertension. 12 patients (66%) fulfilled the criteria for arterial hypertension. Our results illustrate that arterial hypertension diagnosis is devoted an insufficient attention in patients with tinnitus. ABPM should therefore be used in all patients with tinnitus, immediately after its manifestation and also repeatedly during its course. With early diagnosis and treatment of hypertension, some complications, such as myocardial infarction, stroke, heart and/or kidney failure can be thus prevented (Tab. 1, Fig. 5, Ref. 10).

Abstract
Obesity is an independent risk factor for the development and progression of hypertension, cardiovascular disease and chronic kidney disease. There is growing evidence that obesity and associated metabolic abnormalities may induce and accelerate renal complications in essential hypertension. The clustering of obesity and other features of the metabolic syndrome might have important implications for prevention, particularly with regard to whether interventions targeted at visceral obesity would have beneficial effects on cardiovascular and renal morbidity.

Abstract
Extremitovascular ischemic disease (peripheral arterial disease of extremities - PAD) is an important manifestation of systemic atherosclerosis and other arterial diseases of vascular system. The lower the anklebrachial pressure index, the greater the risk of serious cardiovascular events (e.g., acute myocardial infarction, stroke). Prevention and treatment ofextremitovascular disease is discussed in this article.

Abstract
INTRODUCTION Diabetic foot syndrome is often presented as a skin lesion in diabetics. The aim of our study was to analyse foot ulcerations in diabetics, together with ethiopatogenesis, location and grade of impairment. METHODS We analysed foot ulcerations in 124 diabetics who attended outpatient foot clinic, or were hospitalized in the period from 1996 to 2006. Basic neuropathy screening examination was made with cotton wisp, pin-prick, tuning fork, and monofilament. Beside the evaluation of the presence of pedal pulses, the ankle-brachial pressure index was measured. If the infection of foot ulceration was present, bacteriology examinations was performed. Wagner and University of Texas classifications of foot ulcerations were applied, moreover, location of ulcerations was analysed. RESULTS Neuropathic ulcer was diagnosed in 46 patients of the total number of 124 (37%), neuroischemic in 76 patients (61%) and pure ischemic ulcer only in 2 patients (2%). Neuropathy was present in 122 (98%) patients with diabetic foot, limb ischemia in 78 patients (63%). Fifty four per cent of foot ulcers were located on toes and 43% ulcers on plantar surface. Foot ulcer infection was detected in 72 patients (58%). We found 48 superficial ulcers (38.7%) and 76 deep ulcers (61.3%). In diabetics without foot ischemia and infection 39% deep ulcers were present whereas in the group with ischemia and infection the proportion amounted to 80% (p < 0.05). CONCLUSION Diabetic foot syndrom was present more often in type-2 diabetics with longer disease duration, in those on insulin treatment, in men of older age, further in the diabetics with pure glycemic control and/or with chronic microvascular diabetic complications.
