Tubular and Glomerular Size by Cortex Depth as Predictor of Progressive CKD after Radical Nephrectomy for Tumor. J Am Soc Nephrol 2023; 34:1535-1545. [PMID: 37430426 PMCID: PMC10482069 DOI: 10.1681/asn.0000000000000180] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 06/08/2023] [Indexed: 07/12/2023] Open
Abstract
SIGNIFICANCE STATEMENT Glomerular size differs by cortex depth. Larger nephrons are prognostic of progressive kidney disease, but it is unknown whether this risk differs by cortex depth or by glomeruli versus proximal or distal tubule size. We studied the average minor axis diameter in oval proximal and distal tubules separately and by cortex depth in patients who had radical nephrectomy to remove a tumor from 2019 to 2020. In adjusted analyses, larger glomerular volume in the middle and deep cortex predicted progressive kidney disease. Wider proximal tubular diameter did not predict progressive kidney disease independent of glomerular volume. Wider distal tubular diameter showed a gradient of strength of prediction of progressive kidney disease in the more superficial cortex than in the deep cortex. BACKGROUND Larger nephrons are prognostic of progressive kidney disease, but whether this risk differs by nephron segments or by depth in the cortex is unclear. METHODS We studied patients who underwent radical nephrectomy for a tumor between 2000 and 2019. Large wedge kidney sections were scanned into digital images. We estimated the diameters of proximal and distal tubules by the minor axis of oval tubular profiles and estimated glomerular volume with the Weibel-Gomez stereological model. Analyses were performed separately in the superficial, middle, and deep cortex. Cox proportional hazard models assessed the risk of progressive CKD (dialysis, kidney transplantation, sustained eGFR <10 ml/min per 1.73 m 2 , or a sustained 40% decline from the postnephrectomy baseline eGFR) with glomerular volume or tubule diameters. At each cortical depth, models were unadjusted, adjusted for glomerular volume or tubular diameter, and further adjusted for clinical characteristics (age, sex, body mass index, hypertension, diabetes, postnephrectomy baseline eGFR, and proteinuria). RESULTS Among 1367 patients were 62 progressive CKD events during a median follow-up of 4.5 years. Glomerular volume predicted CKD outcomes at all depths, but only in the middle and deep cortex after adjusted analyses. Proximal tubular diameter also predicted progressive CKD at any depth but not after adjusted analyses. Distal tubular diameter showed a gradient of more strongly predicting progressive CKD in the superficial than deep cortex, even in adjusted analysis. CONCLUSIONS Larger glomeruli are independent predictors of progressive CKD in the deeper cortex, whereas in the superficial cortex, wider distal tubular diameters are an independent predictor of progressive CKD.

Therapeutic potential of melatonin in colorectal cancer: Focus on lipid metabolism and gut microbiota. Biochim Biophys Acta Mol Basis Dis 2022; 1868:166281. [PMID: 34610472 DOI: 10.1016/j.bbadis.2021.166281] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Revised: 08/24/2021] [Accepted: 09/26/2021] [Indexed: 12/24/2022]
Abstract
Colorectal cancer (CRC) is one of the most common gastrointestinal malignancies. The occurrence and development of CRC are complicated processes. Obesity and dysbacteriosis have been increasingly regarded as the main risk factors for CRC. Understanding the etiology of CRC from multiple perspectives is conducive to screening for some potential drugs or new treatment strategies to limit the serious side effects of conventional treatment and prolong the survival of CRC patients. Melatonin, a natural indoleamine, is mainly produced by the pineal gland, but it is also abundant in other tissues, including the gastrointestinal tract, retina, testes, lymphocytes, and Harder's glands. Melatonin could participate in lipid metabolism by regulating adipogenesis and lipolysis. Additionally, many studies have focused on the potential beneficial effects of melatonin in CRC, such as promotion of apoptosis; inhibition of cell proliferation, migration, and invasion; antioxidant activity; and immune regulation. Meaningfully, gut microbiota is the main determinant of all aspects of health and disease (including obesity and tumorigenesis). The gut microbiota is of great significance for understanding the relationship between obesity and increased risk of CRC. Although the current understanding of how the melatonin-mediated gut microbiota coordinates a variety of physiological and pathological activities is fairly comprehensive, there are still many unknown topics to be explored in the face of a complex nutritional status and a changeable microbiota. This review summarizes the potential links among melatonin, lipid metabolism, gut microbiota, and CRC to promote the development of melatonin as a preventive and therapeutic agent for CRC.

Melatonin Attenuates Dextran Sodium Sulfate Induced Colitis in Obese Mice. Pharmaceuticals (Basel) 2021; 14:ph14080822. [PMID: 34451919 PMCID: PMC8399719 DOI: 10.3390/ph14080822] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Revised: 08/16/2021] [Accepted: 08/18/2021] [Indexed: 01/03/2023] Open
Abstract
Epidemiological studies have indicated that obesity is an independent risk factor for colitis and that a high-fat diet (HFD) increases the deterioration of colitis-related indicators in mice. Melatonin has multiple anti-inflammatory effects, including inhibiting tumor growth and regulating immune defense. However, the mechanism of its activity in ameliorating obesity-promoted colitis is still unclear. This study explored the possibility that melatonin has beneficial functions in HFD-induced dextran sodium sulfate (DSS)-induced colitis in mice. Here, we revealed that HFD-promoted obesity accelerated DSS-induced colitis, while melatonin intervention improved colitis. Melatonin significantly alleviated inflammation by increasing anti-inflammatory cytokine release and reducing the levels of proinflammatory cytokines in HFD- and DSS-treated mice. Furthermore, melatonin expressed antioxidant activities and reversed intestinal barrier integrity, resulting in improved colitis in DSS-treated obese mice. We also found that melatonin could reduce the ability of inflammatory cells to utilize fatty acids and decrease the growth-promoting effect of lipids by inhibiting autophagy. Taken together, our study indicates that the inhibitory effect of melatonin on autophagy weakens the lipid-mediated prosurvival advantage, which suggests that melatonin-targeted autophagy may provide an opportunity to prevent colitis in obese individuals.

Abstract
Combination therapies with chemotherapy and traditional Chinese medicines are attracted increasing attentions for cancer treatment in China. Shengbai decoction (SBD) is a traditional Chinese compound medicine, composed of 6 traditional Chinese herbs. The aim of this study was to investigate the synergistic anti-tumor activity of SBD with cyclophosphamide (CTX) and the possibly underlying mechanisms in treating the hepatoma 22 (H22) -bearing mice. The liver cancer models in C57BL/6 mice were established by injecting with mouse H22 cancer cells. Results showed that combination treatment with SBD and CTX processed a significantly synergistic anti-tumor effect in H22 tumor-bearing mice. Moreover, SBD could not only improve leukopenia caused by CTX, but prolong the survival time of the mice. Furthermore, SBD could upregulate the expressions of the pro-apoptotic genes, including p53, BAD, Cas3 and Bax, and suppress the expression of anti-apoptotic gene Bcl-2. These results suggested that the combination treatment with SBD and CTX had health improving function and less side effects compared with the administration of CTX alone, and SBD could be a promising adjunct agent for liver cancer chemotherapy.

Abstract
Melatonin has shown promising effects in controlling the progress of non-alcoholic fatty liver disease (NAFLD), introducing it as a possible candidate for NAFLD treatment. In this context, the current study is aimed to evaluate melatonin's effect on the plasma levels of Gamma-glutamyl transpeptidase, cholesterol, triglyceride, and liver aminotransferases in NAFLD patients. NAFLD and melatonin, as well as their related terms, were searched in electronic databases, until May 1st, 2020. The initial search identified 1152 studies. Considering inclusion and exclusion criteria, the final seven articles were included in the study. The methodology of the articles was assessed by the Newcastle-Ottawa Scale. Alanine transaminase levels were significantly lowered with melatonin treatment but not earlier than the 4th week (P = 0.010 and 0.519, respectively). Aspartate aminotransferase levels didn't show significant alteration before 4 weeks, although exhibiting substantial decline in total (P = 0.697 and 0.008, respectively). Alkaline phosphatase changes under 4 weeks of follow-up were not significant (P = 0.3), however, it decreased significantly in total (P = 0.006). A significant decline was detected in triglyceride levels after melatonin treatment (P = 0.015). There was a significant reduction in cholesterol levels (P = 0.005). Gamma-glutamyl transpeptidase levels were also significantly different after the administration of melatonin (P < 0.001). Melatonin could reduce the progress of NAFLD. It might also decrement hepatic function parameters. Thus, it could be used for managing NAFLD and possibly as part of the treatment plan for patients with NAFLD.

Abstract
INTRODUCTION The diameter and area of the proximal convoluted tubule (PCT) and the distal convoluted tubule (DCT) are of the main parameters analyzed in stereological studies of the kidney. However, there is no consensus about if the PCT and DCT should be considered circular or elliptical in shape. OBJECTIVE To analyze if there are significant differences in the diameter and area of the PCT and DCT, depending on whether they are considered circular or elliptical. METHODS Paraffin-embedded sections of kidneys from CD1 mice were stained with hematoxylin and eosin and examined using a light microscope. Images were captured using a camera linked to image analysis software. A short diameter (d) and a long diameter (D) were measured in both PCT and DCT. A small circular area (SCA), a large circular area (LCA), and an elliptical area (EA) were calculated with mathematical formulas that incorporate d and D values, while a program area (PA) was provided by the software. RESULTS There was a significant difference between d and D in both PCT (F = 1.354, Sig = 0.000) and DCT (F = 4.989, Sig = 0.000). Also, there were significant differences in the tubular areas in both PCT (F = 34.843, Sig = 0.000) and DCT (F = 22.390, Sig = 0.000); circular areas were different from elliptical areas (SCA and LCA vs. EA and PA). CONCLUSION The convoluted tubules of the nephron must not be considered circular, but rather elliptical; care should be taken every time the tubules are analyzed in stereological studies of the kidney, especially when evaluating their diameters and areas.

Abstract
Combination antiretroviral therapy (cART), which is a lifelong therapy for people living with human immunodeficiency virus, has been associated with nephrotoxicity and hepatotoxicity leading to its discontinuation. This study aimed at investigating the ameliorative potential of naringenin and quercetin on cART-induced hepatotoxicity and nephrotoxicity. Seventy male Wistar rats (225-260 g) were divided into seven groups as control, cART, naringenin, quercetin, dimethyl sulfoxide (DMSO), naringenin/cART (CN) and quercetin/cART (CQ). cART (24 mg/kg), naringenin (50 mg/kg) and quercetin (50 mg/kg) were dissolved in 1% v/v DMSO and administered orally for 56 days. Combination of cART and bioflavonoids had significant increase in superoxide dismutase (P < 0.05), catalase (P < 0.01), reduced glutathione (P < 0.001) and decreased malondialdehyde (P < 0.001) compared to cART only. Tumor necrosis factor Alpha (TNFα) level increased significantly in cART and CQ (P < 0.01) groups, while others showed no significant changes compared to control. TNFα also significantly decreased in CQ level compared to cART (P < 0.001). In addition, significant increase in creatinine level in cART only indicated progressive renal toxicity. Also, progressive pathological changes including congested blood vessels and hepatocellular necrosis were found in the liver, while the kidney had glomerular atrophy, and tubular distortion in cART-only group. Control, naringenin- and quercetin-treated groups showed normal renal and hepatic cytoarchitecture. These findings elucidate that progressive renal and hepatic toxicity is associated with the continuous use of cART; however, a combination of quercetin and naringenin with cART showed possible potential of ameliorating the damages posed by cART.

IgG Fc-binding motif-conjugated HIV-1 fusion inhibitor exhibits improved potency and in vivo half-life: Potential application in combination with broad neutralizing antibodies.

Abstract
The clinical application of conventional peptide drugs, such as the HIV-1 fusion inhibitor enfuvirtide, is limited by their short half-life in vivo. To overcome this limitation, we developed a new strategy to extend the in vivo half-life of a short HIV-1 fusion inhibitory peptide, CP24, by fusing it with the human IgG Fc-binding peptide (IBP). The newly engineered peptide IBP-CP24 exhibited potent and broad anti-HIV-1 activity with IC50 values ranging from 0.2 to 173.7 nM for inhibiting a broad spectrum of HIV-1 strains with different subtypes and tropisms, including those resistant to enfuvirtide. Most importantly, its half-life in the plasma of rhesus monkeys was 46.1 h, about 26- and 14-fold longer than that of CP24 (t1/2 = 1.7 h) and enfuvirtide (t1/2 = 3 h), respectively. IBP-CP24 intravenously administered in rhesus monkeys could not induce significant IBP-CP24-specific antibody response and it showed no obvious in vitro or in vivo toxicity. In the prophylactic study, humanized mice pretreated with IBP-CP24 were protected from HIV-1 infection. As a therapeutic treatment, coadministration of IBP-CP24 and normal human IgG to humanized mice with chronic HIV-1 infection resulted in a significant decrease of plasma viremia. Combining IBP-CP24 with a broad neutralizing antibody (bNAb) targeting CD4-binding site (CD4bs) in gp120 or a membrane proximal external region (MPER) in gp41 exhibited synergistic effect, resulting in significant dose-reduction of the bNAb and IBP-CP24. These results suggest that IBP-CP24 has the potential to be further developed as a new HIV-1 fusion inhibitor-based, long-acting anti-HIV drug that can be used alone or in combination with a bNAb for treatment and prevention of HIV-1 infection.

Abstract
In the last decade or more, there have been reports suggesting a rise in the incidence of stroke in young adults. Presently, it appears that the risk factors associated with the cause of stroke in young adults remain relatively constant across different geographic regions of the world. Moreover, the endogenous rhythm of a neurohormone such as melatonin is known to play certain roles in the modulation of some of the risk factors that are associated with an increased risk of stroke in young people. Whereas animal studies have shown that melatonin plays diverse roles in stroke, only a limited number of human studies examined the roles of exogenous melatonin administration in the prevention of stroke, attenuation of neuronal damage, and improving outcome or well-being in stroke patients. In this review, first we summarize existing studies of stroke in the young adult and then provide insights on melatonin and stroke. Thereafter, we discuss the role of melatonin in models of stroke and how melatonin can be regulated to prevent stroke in young adults. Finally, we highlight the possible roles of melatonin in the management and outcome of stroke, especially in the young adult stroke population.
