Abstract
PURPOSE Keratin 14 (KRT14) is hypothesized to be involved in the pathogenesis of renal cell carcinoma (RCC) based on its tumorigenic role in various cancers and its relationship with the prognosis of other urinary system malignancies. This study aimed to evaluate the correlation of KRT14 with tumor properties and prognosis in RCC patients. METHODS Data from 180 RCC patients who received tumor resection were retrospectively reviewed. The KRT14 was assessed by immunohistochemistry (IHC) staining in tumor tissues and non-tumor tissues. RESULTS KRT14 was insufficiently expressed in both tumor and non-tumor tissues, with median (interquartile range) IHC score of 2.0 (0.0-3.4) and 1.0 (0.0-2.0), respectively. While it was relatively higher in tumor versus non-tumor tissues (P < 0.001). Besides, tumor KRT14 was positively correlated with the pathological grade (P = 0.038), tumor size (P = 0.012), T stage (P = 0.006), and TNM stage (P = 0.018). Interestingly, tumor KRT14 high predicted shorter accumulating recurrence-free survival (RFS) (P = 0.003) and accumulating overall survival (OS) (P = 0.001), which was further verified by the multivariate Cox's regression analysis (both P < 0.05). Furthermore, tumor KRT14 high estimated shorter RFS and OS from the Gene Expression Profiling Interactive Analysis and Human Protein ATLAS databases (all P < 0.05). Subgroup analyses indicated that the correlation of tumor KRT14 with accumulating RFS and accumulating OS was more pronounced in RCC patients with better physical status (such as age < 65 years and better eastern cooperative oncology group performance status) and higher tumor stages (such as higher pathological grade). CONCLUSION High KRT14 in tumor tissue could reflect an advanced tumor features and unsatisfying survival in RCC patients.

Shen Qi Wan-Containing Serum Alleviates Renal Interstitial Fibrosis via Restraining Notch1-Mediated Epithelial-Mesenchymal Transition. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2023; 2023:3352353. [PMID: 36793762 PMCID: PMC9925256 DOI: 10.1155/2023/3352353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 11/04/2022] [Accepted: 11/15/2022] [Indexed: 02/09/2023]
Abstract
Objective Shen Qi Wan (SQW) is the most classic prescription for the clinical therapy of chronic kidney disease in China. Nevertheless, the function of SQW in renal interstitial fibrosis (RIF) has not been clearly clarified. Our purpose was to explore the protective function of SQW on RIF. Methods After intervention with SQW-containing serum alone at increasing concentrations (2.5, 5, and 10%) or in combination with siNotch1, the transforming growth factor-beta (TGF-β)-induced HK-2 cell viability, extracellular matrix (ECM)-, epithelial-mesenchymal transition (EMT), and Notch1 pathway-associated protein expressions were assessed by cell counting kit-8, qRT-PCR, western blot, and immunofluorescence assays. Results SQW-containing serum intensified the viability of TGF-β-mediated HK-2 cells. Besides, it augmented the collagen II and E-cadherin levels, and weakened the fibronectin, α-SMA, vimentin, N-cadherin, and collagen I levels in HK-2 cells triggered by TGF-β. Moreover, it is found that TGF-β led to the upregulation of Notch1, Jag1, HEY1, HES1, and TGF-β in HK-2 cells, which was partially offset by SQW-containing serum. Furthermore, cotreatment of SQW-containing serum and Notch1 knockdown further apparently alleviated the Notch1, vimentin, N-cadherin, collagen I, and fibronectin levels in HK-2 cells induced by TGF-β. Conclusion Collectively, these findings elucidated that SQW-containing serum attenuated RIF via restraining EMT through the repression of the Notch1 pathway.

JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:1120242. [PMID: 35340239 PMCID: PMC8941540 DOI: 10.1155/2022/1120242] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Revised: 02/11/2022] [Accepted: 02/14/2022] [Indexed: 11/30/2022]
Abstract
Objective To explore the effects of systematic diet education combined with multidisciplinary nursing on nutritional status and calcium and phosphorus metabolism in patients with diabetic kidney disease (DKD) in uremic phase after treatment with alogliptin. Methods A total of 90 DKD patients with uremia admitted to our hospital from January 2020 to January 2021 were selected as the research objects. The subjects were divided into combined group and routine group by random number table method. All patients received alogliptin medication. The combination group received systematic dietary education combined with multidisciplinary nursing after the medication, and the conventional group received conventional intervention. Serum albumin, blood calcium, and other indexes were detected between both groups after intervention. Results After intervention, compared with the conventional group, all nutritional indexes of the combined group were obviously higher, levels of serum phosphorus and calcium-phosphorus product of the combined group were obviously lower (P < 0.001), the incidence of hypoglycemia and hyperglycemia of the combined group was obviously lower (P < 0.05), the total compliance rate of the combined group was obviously higher (P < 0.05), and the SAS score of the combined group was obviously lower (P < 0.001). Conclusion With conspicuous intervention effect, systematic diet education combined with multidisciplinary nursing is a reliable method that can improve the nutritional status and levels of calcium and phosphorus metabolism, enhance treatment compliance, and reduce anxiety. Further research will help to provide a better solution for patients. This trial is registered with ChiCTR2200057011.

Abstract
Intermediate filament (IntFil) genes arose during early metazoan evolution, to provide mechanical support for plasma membranes contacting/interacting with other cells and the extracellular matrix. Keratin genes comprise the largest subset of IntFil genes. Whereas the first keratin gene appeared in sponge, and three genes in arthropods, more rapid increases in keratin genes occurred in lungfish and amphibian genomes, concomitant with land animal-sea animal divergence (~ 440 to 410 million years ago). Human, mouse and zebrafish genomes contain 18, 17 and 24 non-keratin IntFil genes, respectively. Human has 27 of 28 type I "acidic" keratin genes clustered at chromosome (Chr) 17q21.2, and all 26 type II "basic" keratin genes clustered at Chr 12q13.13. Mouse has 27 of 28 type I keratin genes clustered on Chr 11, and all 26 type II clustered on Chr 15. Zebrafish has 18 type I keratin genes scattered on five chromosomes, and 3 type II keratin genes on two chromosomes. Types I and II keratin clusters-reflecting evolutionary blooms of keratin genes along one chromosomal segment-are found in all land animal genomes examined, but not fishes; such rapid gene expansions likely reflect sudden requirements for many novel paralogous proteins having divergent functions to enhance species survival following sea-to-land transition. Using data from the Genotype-Tissue Expression (GTEx) project, tissue-specific keratin expression throughout the human body was reconstructed. Clustering of gene expression patterns revealed similarities in tissue-specific expression patterns for previously described "keratin pairs" (i.e., KRT1/KRT10, KRT8/KRT18, KRT5/KRT14, KRT6/KRT16 and KRT6/KRT17 proteins). The ClinVar database currently lists 26 human disease-causing variants within the various domains of keratin proteins.

J Steroid Biochem Mol Biol 2021; 214:105956. [PMID: 34348182 DOI: 10.1016/j.jsbmb.2021.105956] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 06/20/2021] [Accepted: 07/21/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND The role of calcitriol (1,25-dihydroxyvitamin D3 or 1,25-(OH)2D3) in physiological processes, such as anti-fibrosis, anti-inflammation, and immunoregulation is known; however, its role in the remodeling of the glomerular capillary endothelium in rats with chronic renal failure (CRF) remains unclear. METHODS Here, we analyzed the role/number of endothelial progenitor cells (EPCs), renal function, and pathological alterations in rats with CRF, and compared the results before and after supplementation with calcitriol in vivo. RESULTS Amongst the three experimental groups (sham group, CRF group, and calcitriol-treated group (0.03 μg/kg/d), we observed substantially elevated cell adhesion and vasculogenesis in vivo in the calcitriol-treated group. Additionally, lower levels of serum creatinine (Scr) and blood urea nitrogen (BUN) was recorded in the calcitriol-treated group than the CRF group (p > 0.05). Calcitriol treatment also resulted in an improvement in renal pathological injury. CONCLUSIONS Thus, calcitriol could ameliorate the damage of glomerular arterial structural and renal tubules vascular network integrity, maybe through regulating the number and function of EPCs in the peripheral blood of CRF rats. Treatment with it may improve outcomes in patients with renal insufficiency or combined cardiac insufficiency. Calcitriol could ameliorate CRF-induced renal pathological injury and renal dysfunction by remodeling of the glomerular capillary endothelium, thus, improving the function of glomerular endothelial cells.

Abstract
BACKGROUND The intestinal mechanical barrier plays a key role in the pathogenesis of ulcerative colitis (UC). Our previous study showed keratin 1 (KRT1) was downregulated in UC, but the mechanism by which KRT1 affects the intestinal barrier remains unknown. OBJECTIVES To explore the mechanism of KRT1 in the intestinal barrier in UC. METHODS Colonic tissues were collected from 20 UC patients before and after mucosal healing (MH) and 15 healthy controls. The expression of KRT1 was measured by PCR, western blotting and immunohistochemistry (IHC). A dextran sulfate sodium (DSS)-induced colitis model was established in krt1 transgenic (TG) mice, and the mice were treated with methylprednisolone (MP) to explore the role of KRT1 in the intestinal barrier. Inflammation was evaluated through the DAI score, colon, spleen and H&E. The expression of KRT1 and tight junction (TJ) proteins in mouse was analysed by the same methods. RESULTS The transcription and expression of KRT1 in UC was decreased and recovered after MH but did not reach the level of the healthy controls. Similar to the clinical results, the expression of krt1 was decreased in DSS-induced colitis and upregulated after MP. Moreover, the krt1 TG group exhibited less inflammation than wild-type (WT) group. The expression of Occludin and ZO-1 decreased after DSS induction, the decreases in Occludin and ZO-1 in the krt1 TG group were lower than WT group, which was significantly increased after MP, while the expression of Claudin-2 exhibited the opposite effect. CONCLUSIONS Keratin 1 maintains the intestinal barrier by upregulating TJ proteins in UC.

Abstract
Background Acute kidney injury with acute renal failure is associated with severe diabetic ketoacidosis. This retrospective study was conducted at a single center in China and aimed to compare combined hemodialysis and hemoperfusion (hemodialysis+hemoperfusion) with hemoperfusion alone in 106 patients with diabetic ketoacidosis and acute renal failure. Material/Methods The 106 patients were divided into 2 groups according to different dialysis programs, with 53 cases in each group. Hemodialysis was performed using a single-pass 4008S FX8 HeLix-One hollow fiber hemodialyzer (Fresenius Medical Care, St. Wendel, Germany). Hemoperfusion was performed using HA130 resin adsorbents. Results There were no significant differences in terms of sex, age, duration of diabetes, A1c, pH, and admission blood glucose between the 2 groups (P=0.54, 0.564, 0.53, 0.78, 0.82, 0.51). There were no significant differences in fasting blood glucose, blood urea nitrogen, osmotic pressure, and creatinine between the 2 groups before treatment (P=0.146, 0.978, 0.786, 0.983). After treatment, blood urea nitrogen and creatinine in the dual-treatment group were lower than in the control group, and the osmotic pressure was higher than that in the control group (P=0.000, 0.000, 0.000). The dual-treatment group experienced a lower prevalence of dizziness (5.7%), anemia (7.5%), bone pain (7.5%), hypertension (3.8%), and pruritus (5.7%) than the control group (P<0.05). Conclusions Compared with hemoperfusion alone, hemodialysis+hemoperfusion significantly reduced pruritus and anemia, improved renal function, and was associated with significantly fewer adverse events in patients with diabetic ketoacidosis and acute renal failure.
