#1
Yuqin Wang, William J Griffiths
PURPOSE OF REVIEW: To update researchers of recently discovered metabolites of cholesterol and of its precursors and to suggest relevant metabolic pathways. RECENT FINDINGS: Patients suffering from inborn errors of sterol biosynthesis, transport and metabolism display unusual metabolic pathways, which may be major routes in the diseased state but minor in the healthy individual. Although quantitatively minor, these pathways may still be important in healthy individuals...

Background: Cardiovascular disease is the most common cause of mortality in haemodialysis (HD) patients and is highly predicted by markers of chronic inflammation. Regular exercise may have beneficial anti-inflammatory effects, but this is unclear in HD patients. This study assessed the effect of regular intradialytic exercise on soluble inflammatory factors and inflammatory leucocyte phenotypes. Methods: Twenty-two HD patients from a centre where intradialytic cycling was offered thrice weekly and 16 HD patients receiving usual care volunteered...

In folklore medicine, the plant Emilia sonchifolia, belonging to the family Asteraceae, is used for treating tumour and inflammation. In our previous studies, we have done a thorough phytochemical investigation of E. sonchifolia with a report on its potent antimetastatic activity. Further, we isolated and characterised its active fraction (AFES) containing the major compound γ-humulene with an evaluation of the antiangiogenic effect of AFES (5 mg/kg b.wt.). In the first part of the present study, AFES in different concentrations was used for the assessment of its possible anti-inflammatory effect employing three in vivo inflammatory models...

BACKGROUND: Several histological high-risk factors are used as an indication for adjuvant therapy in stage II colon cancer. Those and other factors, including lymphatic invasion, perineural invasion (PNI), venous invasion and tumour budding are associated with decreased outcome. In this study, we evaluated the prognostic and predictive values of these biomarkers in a cohort of rectal cancer patients. MATERIALS AND METHODS: The trial-based cohort consisted of 221npTNM stage II-III rectal cancer patients, included in the PROCTOR/SCRIPT trial, a multicentre randomised phase III trial...

KLK13 downregulation occurs in tumour tissues in comparison with adjacent normal tissues from patients with oesophageal squamous cell carcinoma (OSCC). KLK13 mRNA levels were tested in OSCC tumour tissues and adjacent noncancerous tissues from 138 patients. In addition, the correlation between KLK13 mRNA levels and OSCC clinicopathologic features was analysed. KLK13 mRNA levels decreased notably in tumour tissues compared with those in adjacent noncancerous tissues. And decreased KLK13 mRNA levels indicated significant correlations with higher tumour grade, elevated TNM (UICC, 2009) stage classification, deeper infiltration and more lymph node metastases...

AIMS: Hepatic progenitor cells (HPCs) are activated in various liver diseases but their role in carcinomatous environment remains unknown. We aimed to identify the possible presence and topography of HPCs in liver metastases. METHODS: We examined 14 liver resection specimens for colorectal adenocarcinoma (CRC) (n=13) and anal squamous cell carcinoma (SCC) (n=1) metastases. Immunohistochemical markers of colonic (keratin 20-K20, CDX2) and squamous cell origin (p63), HPC (K19, CD56) and stem cell (CD44) markers, and the biliary marker K7 which may also highlight HPCs were applied on routinely processed tissue sections...

AIMS: During pathological examination of breast tumours, proliferative activity is routinely evaluated by a count of mitoses. Adding immunohistochemical stains of Ki67 provides extra prognostic and predictive information. However, currently used methods for these evaluations suffer from imperfect reproducibility. It is still unclear whether analysis of Ki67 should be performed in hot spots, in the tumour periphery or as an average of the whole tumour section. In this paper, we compare the clinical relevance of mitoses, Ki67 and Phosphohistone H3 in two cohorts of primary breast cancer specimens (total n=294)...

OBJECTIVES: To determine whether clinically relevant portal hypertension (CRPH) influences outcome and whether it may serve as a prognostic marker in patients treated with transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). METHODS: One hundred and forty-seven patients underwent conventional TACE as a first-line treatment for a single HCC. CRPH was graded as 0, 1, or 2. The influence of CRPH, together with other factors, on local tumour progression (LTP) and overall survival (OS) were analysed using Cox proportional hazards regression...

Dupuytren's disease is a common fibrotic condition of the hand affecting 4% of the population and causes the fingers to curl irreversibly into the palm. It has a strong familial tendency, there is no approved treatment for early stage disease, and patients with established digital contractures are most commonly treated by surgery. This is associated with prolonged recovery, and less invasive techniques have high recurrence rates.The myofibroblasts, the cells responsible for the excessive matrix deposition and contraction, are aggregated in nodules...

BACKGROUND: Regional or diffuse fibrosis is an early feature of hypertrophic cardiomyopathy (HCM) and is related to poor prognosis. Previous studies have documented low-grade inflammation in HCM. The aim of this study was to examine the relationships between circulating inflammatory markers and myocardial fibrosis, systolic and diastolic dysfunction, and the degree of cardiac hypertrophy in HCM patients. METHODS AND RESULTS: Fifty HCM patients were recruited while 20 healthy subjects served as the control group...

A 60-year-old man presented with unilateral testicular pain and urinary frequency. His presenting prostate-specific antigen (PSA) was 100 ng/mL, and a biopsy revealed Gleason 4+4 prostate adenocarcinoma. The significance of his initial PSA was somewhat complicated by possible prostatitis and early initiation of bicalutamide. PSA rose on two occasions prior to radiotherapy but coincided with a flare of testicular pain on one of these. Whole-body staging diffusion-weighted MRI scan was negative. He was treated with 3 years of androgen deprivation therapy (ADT) and radical radiotherapy...

BACKGROUND: The G protein estrogen receptor GPER/GPR30 mediates estrogen action in breast cancer cells as well as in breast cancer-associated fibroblasts (CAFs), which are key components of microenvironment driving tumor progression. GPER is a transcriptional target of hypoxia inducible factor 1 alpha (HIF-1α) and activates VEGF expression and angiogenesis in hypoxic breast tumor microenvironment. Furthermore, IGF1/IGF1R signaling, which has angiogenic effects, has been shown to activate GPER in breast cancer cells...

Background: Glioblastoma is the commonest form of malignant brain tumour in adults, affecting 2-3 people per 100,000 per year. Despite current treatment options including surgical resection, radiotherapy and temozolomide chemotherapy, overall survival at 2 years is approximately 27%, with a median survival of 12-14 months. The ketogenic diet (KD) is postulated to work by simulating the metabolic response to fasting by promoting the utilisation of ketones as a primary energy source, and depriving the glycolytic pathways utilised by malignant glioma cells for growth...

Diffuse Large B-Cell Lymphoma (DLBCL) is the most common histological subtype of Non-Hodgkin's Lymphoma (NHL). Primary retroperitoneal DLBCL is uncommon and has seldom been reported. Extrinsic compression of the duodenum due to lesions originating from the retroperitoneum is also rare. We present a case of a 39-year-old man who presented with inability to tolerate oral intake, abdominal pain, an upper abdominal mass and postprandial bilious vomiting caused by a large DLBCL arising from the retroperitoneum causing extrinsic compression of the duodenum...

BACKGROUND: HER2 status is significant to trastuzumab therapy; however, it is difficult to determine HER2 status accurately with few pieces of biopsies from advanced gastric cancer (AGC) due to highly heterogeneity and invasive behaviour, which will be investigated in this study. METHODS: Fifty-six patients with AGC were included in this study. Primary tumour tissues and matched plasmas before medication from 36 patients were retrospectively collected, and the other 20 patients with primary tumour tissues and paired plasmas were prospectively collected...

AIMS: To investigate the clinicopatholoigcal and molecular features of primary effusion lymphoma (PEL) in Taiwan and the association with HIV, HHV8, and EBV. METHODS AND RESULTS: We retrospectively investigated 26 cases with a median age of 76.5. Only one (4%) patient was infected with HIV. Cytologically, all lymphoma cells revealed typical immunoblastic to plasmablastic morphology. Immunohistochemically, HHV8 was positive in 8 (32%) tumours, negative in 17 (68%) cases...

AIMS: Denosumab, a human monoclonal antibody directed against the receptor activator of nuclear factor-kappa B ligand (RANKL), is a therapeutic agent for giant cell tumour of bone (GCTB). Although some studies reported that denosumab shrinks tumours and induces bone formation, the actual effects of RANKL suppression on GCTB remain unclear. A mutation in the H3 histone family member 3A gene (H3F3A) was recently identified as a genetic signature for GCTB. The aim of this study was to investigate the histopathological features and H3F3A mutation status of GCTBs treated with denosumab...

It is well established that tumour cells have metabolic differences when compared with normal cells. This is particularly true for energy metabolism in which dogs with cancer have been reported to have higher blood insulin and lactate concentrations than control dogs. Moreover, some human and animal studies suggest that the insulin-like growth factor 1 (IGF-1) signalling pathway may play a role in tumorigenesis and tumour progression. At present, IGF-1 has not been evaluated in dogs with multicentric lymphoma...

BACKGROUND: Neutrophil to lymphocyte ratio (NLR), C-reactive protein (CRP) and Glasgow Prognostic Score (GPS) have demonstrated good prognostic value in several cancers but their role in gallbladder cancer (GBC) remains unclear. The aim of this study is to systematically review the current literature to determine their role in predicting survival outcomes in GBC. METHODS: Using a pre-specified inclusive search strategy MEDLINE, EMBASE and CINAHL databases were used to identify studies describing survival in patients after GBC resection with high or low pre-operative CRP, GPS or NLR...
