    Abstract FSGS is a pathologic lesion that frequently causes the nephrotic syndrome and ensuing renal failure. The cause remains unknown in the majority of individuals; however, in the past two decades, rare familial forms have been identified. It has been suggested that known genetic causes of the hereditary form of this disease account for upwards of 18% of cases. Mutations in five genes have been found to cause inherited nephrotic syndromes and FSGS. In this article, I discuss the phenotypic characteristics of hereditary FSGS and the transient receptor potential cation channel 6 (TRPC6) protein, which is the genetic impetus for an autosomal dominant form of FSGS. The TRP channels have been implicated in varied biologic functions such as mechanosensation, ion homeostasis, cell growth, and phospholipase C-dependent calcium entry into cells. The mutated ion channel causes an increase in calcium transients. Current evidence also suggests that blocking TRPC6 channels may be of therapeutic benefit in idiopathic FSGS, a disease with a generally poor prognosis. Preliminary experiments reveal that the commonly used immunosuppressive agent FK-506 can inhibit TRPC6 activity in vivo. This creates the intriguing possibility that blocking TRPC6 channels within the podocyte may translate into long-lasting clinical benefits in patients with FSGS.

    Abstract Introduction: Body mass index (BMI) fails to identify up to one-third of normal weight individuals with metabolic dysfunction who may be at increased risk of obesity-related cancer (ORC). Metabolic obesity phenotypes, an alternate metric to assess metabolic dysfunction with or without obesity, were evaluated for association with ORC risk.
    Methods: National Health and Nutrition Examination Survey participants from 1999 to 2018 (N = 19,500) were categorized into phenotypes according to the metabolic syndrome (MetS) criteria and BMI: metabolically healthy normal weight (MHNW), metabolically unhealthy normal weight (MUNW), metabolically healthy overweight/obese (MHO) and metabolically unhealthy overweight/obese (MUO). Adjusted multivariable logistic regression models were used to evaluate associations with ORC.
    Results: With metabolic dysfunction defined as ≥1 MetS criteria, ORC cases (n = 528) had higher proportions of MUNW (28.2% vs. 17.4%) and MUO (62.6% vs. 60.9%) phenotypes than cancer-free individuals (n = 18,972). Compared with MHNW participants, MUNW participants had a 2.2-times higher ORC risk [OR (95%CI) = 2.21 (1.27-3.85)]. MHO and MUO participants demonstrated a 43% and 56% increased ORC risk, respectively, compared to MHNW, but these did not reach statistical significance [OR (95% CI) = 1.43 (0.46-4.42), 1.56 (0.91-2.67), respectively]. Hyperglycaemia, hypertension and central obesity were all independently associated with higher ORC risk compared to MHNW.
    Conclusions: MUNW participants have a higher risk of ORC than other abnormal phenotypes, compared with MHNW participants. Incorporating metabolic health measures in addition to assessing BMI may improve ORC risk stratification. Further research on the relationship between metabolic dysfunction and ORC is warranted.

    Abstract Focal segmental glomerulosclerosis (FSGS) is a pathological entity that is a significant cause of morbidity and mortality throughout the world. It is also a significant cause of end-stage renal disease (ESRD). Glomerular disease is the third leading cause of ESRD, and FSGS comprises a significant proportion of this subgroup. Up to 20% of individuals with ESRD have FSGS. It has been reported in patients from varied ethnic backgrounds including individuals who are of Spanish, North American, North European and African descent. The diagnosis of FSGS is based on renal pathology and requires the presence of areas of glomerular sclerosis and tuft collapse that are both focal and segmental. The clinical hallmarks of FSGS include proteinuria, nephrotic syndrome and, frequently, the progressive loss of renal function. At present, there are no consistently reliable treatments for FSGS and response rates to available treatments have been estimated at <30-50%. FSGS has been characterized previously as having primary (idiopathic), secondary and familial forms. In the latter category, both autosomal recessive and dominant inheritance patterns have been reported. Advances in molecular genetics technology and mapping, including high-throughput genotyping for genomic screening, provide powerful tools for the analysis of renal diseases. Genes associated with many familial renal disorders that lead to ESRD have been isolated; these include Alport's nephropathy, familial juvenile nephronophthisis and adult polycystic disease. Recently, the genetic mutation (ACTN4) causing a form of autosomal dominant FSGS (ACTN4) and congenital nephrotic syndromes (NPHS2) have been described. The existence of hereditary forms of FSGS permits the use of molecular genetics techniques to study the pathogenesis of this disorder.

    Abstract Monogenic nephrotic syndrome (nephrotic syndrome caused by a single gene defect) is responsible for only a small percentage of cases of nephrotic syndrome, but information from studies of the unique cohort of patients with this form of the disease has dramatically improved our understanding of the disease pathogenesis. The use of genetic testing in the management of children and adults with nephrotic syndrome poses unique challenges for clinicians in terms of who to test and how to use the information obtained from testing in the clinical setting. In our view, not enough data exist at present to justify the routine genetic testing of all patients with nephrotic syndrome. Testing is warranted, however, in patients with congenital nephrotic syndrome (onset at 0-3 months), infantile nephrotic syndrome (onset at 3-12 months), a family history of nephrotic syndrome, and those in whom nephrotic syndrome is associated with other congenital malformations. The family and/or the patient should be given complete and unbiased information on the potential benefits and risks associated with therapy, including the reported outcomes of treatment in patients with similar mutations. Based on the data available in the literature so far, intensive immunosuppressive treatment is probably not indicated in monogenic nephrotic syndrome if complete or partial remission has not been achieved within 6 weeks of starting treatment. We advocate that family members of individuals with genetic forms of nephrotic syndrome undergo routine genetic testing prior to living-related kidney transplantation. Prospective, multicentre studies are needed to more completely determine the burden of disease caused by monogenic nephrotic syndrome, and randomized controlled trials are needed to clarify the presence or absence of clinical responses of monogenic nephrotic syndrome to available therapies.

    Abstract Multiple lines of evidence have demonstrated that cigarette smoke or Chronic Obstructive Pulmonary Disease upregulates angiotensin-converting enzyme 2, the cellular receptor for the entry of the severe acute respiratory syndrome coronavirus 2, which predisposes individuals to develop severe Coronavirus disease 2019. The reason for this observation is unknown. We recently reported that the loss of function of Miz1 in the lung epithelium in mice leads to a spontaneous COPD-like phenotype, associated with upregulation of angiotensin-converting enzyme 2. We also reported that cigarette smoke exposure downregulates Miz1 in lung epithelial cells and in mice, and Miz1 is also downregulated in the lungs of COPD patients. Here, we provide further evidence that Miz1 directly binds to and represses the promoter of angiotensin-converting enzyme 2 in mouse and human lung epithelial cells. Our data provide a potential molecular mechanism for the upregulation of angiotensin-converting enzyme 2 observed in smokers and COPD patients, with implication in severe Coronavirus disease 2019.

    Abstract Lung cancer is the third most common cancer with Black/AA men showing higher risk and poorer outcomes than NHW men. Lung cancer disparities are multifactorial, driven by tobacco exposure, inequities in care access, upstream health determinants, and molecular determinants including biological and genetic factors. Elevated expressions of protein arginine methyltransferases (PRMTs) correlating with poorer prognosis have been observed in many cancers. Most importantly, our study shows that PRMT6 displays higher expression in lung cancer tissues of Black/AA men compared to NHW men. In this study, we investigated the underlying mechanism of PRMT6 and its cooperation with PRMT1 to form a heteromer as a driver of lung cancer. Disrupting PRMT1/PRMT6 heteromer by a competitive peptide reduced proliferation in non-small cell lung cancer cell lines and patient-derived organoids, therefore, giving rise to a more strategic approach in the treatment of Black/AA men with lung cancer and to eliminate cancer health disparities.

    Abstract Focal and segmental glomerulosclerosis (FSGS) is a pathologic entity that is a common and increasing cause of end-stage renal disease. Typical manifestations include proteinuria, hypertension, worsening renal insufficiency, and, frequently, renal failure. The etiology, however, remains unknown in a majority of patients. There is an estimated recurrence rate of 30% to 40% in renal transplant patients, suggesting that the pathogenesis is not solely a result of intrinsic kidney disease. Although some of its characteristics have been reported, the precise identification of a circulating factor associated with FSGS has not been made. Remarkable progress has been made in recent years regarding biologic mechanisms surrounding FSGS and proteinuria. Insight into the pathogenesis of FSGS has been gained through the study of hereditary forms of FSGS and nephrotic syndromes. Mutations in cytoskeletal proteins that affect podocyte structure have been the target until recently. Here we review the current understanding of this glomerular disease and areas for future concentration.
