GSE184256 Chronic Kidney Disease in a Murine Model of non-Alcoholic Steatohepatitis (NASH)

Contributors : Xuezhu Li ; Dipankar Bhattacharya ; Scott L Friedman ; John C HeSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusNon-alcoholic steatohepatitis (NASH) is a severe form of non-alcoholic fatty liver disease (NAFLD) that underlies a growing prevalence of cirrhosis and liver cancer worldwide. Clinical studies suggest that NASH is an independent risk factor for chronic kidney disease (CKD), but models and mechanisms linking these two diseases are lacking. Here, we have characterized the renal function, histological features, and transcriptomic profile in a well-validated murine NASH model generated by feeding a western diet (WD), with high contents of fat, fructose, and cholesterol, combined with a low dose of weekly IP carbon tetrachloride (CCl4).NASH mice developed significant glomerulosclerosis, tubular epithelial cell injury, and interstitial fibrosis at an intermediate stage (12 weeks). Animals with advanced NASH (24 weeks) displayed renal dysfunction, proteinuria, and renal fibrosis characterized by increased collagen deposition as tubulointerstitial fibrosis, tubular atrophy, and inflammatory cell infiltration. Mice treated with a low dose of CCl4 alone did not develop renal injury, thereby excluding the possibility of CCl4-induced nephrotoxicity. Transcriptomic analysis of kidney cortices revealed differentially expressed genes (DEGs) that were highly enriched in mitochondrial dysfunction, ATP synthesis, and oxidative str...

This study reports the clinicopathologic features of 31 cases with a TP53 mutation involving nuclear localization, the largest study to date, emphasizing practical strategies for recognizing this uncommon variant and distinguishing it from the p53 wild-type pattern. The study also evaluates the prognostic significance of TP53 mutation involving nuclear localization in the ovarian high-grade serous carcinoma (HGSC) cohort of The Cancer Genome Atlas database. Most of the 31 tumors were advanced stage pelvic or endometrial HGSC. All TP53 mutations were predicted to result in loss of function. The p53 overexpression pattern wa...

This study supports the proposal for the usage of the term “EBV-associated pulmonary carcinoma” to encompass the entire morphologic spectrum of this distinct EBV-associated disease entity.

We examined whole‐tissue sections from 111 SGTs with molecular characterization, including 26 SCs (23 with ETV6-NTRK3 fusion and 3 with ETV6-RET fusion detected by ligation-dependent reverse transcription-polymerase chain reaction, next-generation sequencing and 85 non-SC SGTs (no ETV6-NTRK3 fusion). Immunohistochemistry was performed with a pan‐TRK rabbit monoclonal antibody. When any pan‐TRK staining (nuclear or cytoplasmic with any staining intensity) was considered to indicate positivity, 22 of 23 SCs with ETV6-NTRK3 fusion (95.7%) and 33 of 85 non‐SC (38.8%) salivary neoplasms were positive, mainly basal cell ...

Extraneural metastases of glioblastoma (GBM), although rare, are becoming an increasingly recognized occurrence. Currently, the biological mechanism underlying this rare occurrence is not understood. To explore the potential genomic drivers of extraneural metastasis in GBM, we present the molecular features of 4 extraneural metastatic GBMs, along with a comprehensive review and analysis of previously reported cases that had available molecular characterization. In addition to our 4 cases, 42 patients from 35 publications are reviewed. To compare the molecular profiles between GBM cases with extraneural metastasis and the g...

High-grade prostatic adenocarcinoma involving duct/acinar structures is labeled intraductal carcinoma of the prostate (IDCP). As numerous studies have shown that IDCP is associated with high stage disease with a significant negative impact on cancer-specific survival, accurate diagnosis is crucial to ensure appropriate patient management. The definition of IDCP recommended by 2016 World Health Organization (WHO) classification suggests that cases of IDCP with micropapillary or loose cribriform architecture without comedonecrosis should have cells with ≥6× nuclear enlargement. It is unclear how this size criterion ...

We report a novel NIPBL-NACC1 gene fusion in a rare primary hepatic neoplasm previously described as the “cholangioblastic variant of intrahepatic cholangiocarcinoma.” The 2 index cases were identified within our consultation files as morphologically distinctive primary hepatic neoplasms in a 24-year-old female and a 54-year-old male. The neoplasms each demonstrated varied architecture, including trabecular, organoid, microcystic/follicular, and infiltrative glandular patterns, and biphasic cytology with large, polygonal eosinophilic cells and smaller basophilic cells. The neoplasms had a distinctive immunoprof...

Discussion Anorexia nervosa is an eating disorder with an intense fear of being overweight (i.e. distorted body image), and self-starvation and excessive weight loss. It is more common in women (1.2%) than men (0.2%) but can be seen in both genders. Risk factors include high-intelligence, perfectionism/inflexibility, anxiety, activities where thinner body types are expected (e.g. dancer, diver, gymnast, long-distance runner, volleyball player, etc.) Other eating disorders include bulimia nervosa (i.e. cycles of binge eating and then purging), binge eating disorder (i.e. purging), orthorexia (i.e. obsessions with healthful ...

OBJECTIVES: To assess outcomes of cancer patients receiving kidney replacement therapy due to acute kidney injury in ICUs and compare these with other patient groups receiving kidney replacement therapy in ICUs. DESIGN: Retrospective registry analysis. SETTING: Prospectively collected database of 296,424 ICU patients. PATIENTS: Patients with and without solid cancer with acute kidney injury necessitating kidney replacement therapy were identified and compared with those without acute kidney injury necessitating kidney replacement therapy. INTERVENTIONS: Descriptive statistics were used to as...

The objective of this study was to identify the psychosocial factors involved in delayed consultation. We used a qualitative approach, conducting semi-structured interviews with advanced basal cell carcinoma patients and the healthcare staff of a dermatology unit to explore why some patients consult only when basal cell carcinoma is advanced. We then put our findings into perspective and created a logical model for change. We interviewed 14 patients and 12 healthcare staff. The first lesion was associated with banalization. Then, denial and fear of diagnosis or treatment were post common. Finally, the advanced basal cell c...
