Chronical alcohol abuse causes more than 200 diseases and/or symptoms and among these alcoholic liver disease (ALD) is of special importance since it occurs frequently and may be life-threatening. In Europe alcohol consumption as well as ALD increased as compared to the rest of the world. It has been estimated that in Europe approximately 500 000 people die every year due to ALD. ALD consists of alcoholic fatty liver, alcoholic steatohepatitis (ASH), alcoholic cirrhosis and hepatocellar cancer (HCC ). Alcohol hepatitis (AH) is a clinical feature with jaundice and liver failure and a high mortality...

Targeting drug carrier systems based on graphene oxide (GO) are of great interest, since it can selectively deliver anticancer drugs to tumor cells, and enhance therapeutic activities with minimized side effects. However, direct grafting target molecules on GO usually results in aggregation of physiological fluid, limiting its biomedical applications. Here, we propose a new strategy to construct targeting GO drug carrier using folic acid grafted bovine serum albumin (FA-BSA) as both the stabilizer and targeting agent...

Aromatase inhibition is one of the cornerstones of modern endocrine therapy of oestrogen receptor-positive (ER+) metastatic breast cancer (MBC). The nonsteroidal aromatase inhibitors anastrozole and letrozole, as well as the steroidal aromatase inactivator exemestane, are the preferred drugs and established worldwide in all clinical phases of the disease. However, although many patients suffering from MBC experience an initial stabilisation of their metastatic burden, drug resistance and disease progression occur frequently, following in general only a few months on treatment...

Recently radiolabeled ligands targeting prostate specific membrane antigen (PSMA) have been introduced for diagnostics and treatment of prostate cancer. Labeled with Lutetium, PSMA radioligand therapy (RLT) is one of the most promising new treatments of metastatic castration refractory prostate cancer. We present images of Ga-PSMA PET/CT and parameters of response of a 75-year-old heavily pretreated metastatic castration refractory prostate cancer patient with extended bone metastases, showing an extraordinary biochemical response in PSA-levels concordant to SUV decline in bone metastases...

Cancers are the leading cause of deaths all over the world. Available anticancer agents used in clinics exhibit low therapeutic index and usually high toxicity. Wide spreading drug resistance of cancer cells induce a demanding need to search for new drug targets. Currently, many on-going studies on novel compounds with potent anticancer activity, high selectivity as well as new modes of action are conducted. In this work, we describe in details three enzyme groups, which are at present of extensive interest to medical researchers and pharmaceutical companies...

BAG3, a member of BAG co-chaperone family, is induced by stressful stimuli such as heat shock and heavy metals. Through interaction with various binding partners, BAG3 is thought to play a role in cellular adaptive responses against stressful conditions in normal and neoplastic cells. 2'-Hydroxycinnamaldehyde (HCA) is a natural derivative of cinnamaldehyde and has antitumor activity in various cancer cells. In the present study, for the first time, we identified that HCA induced BAG3 expression and BAG3-mediated apoptosis in cancer cells...

PURPOSE OF REVIEW: This article discusses the pathogenesis, diagnosis, and management of autoimmune myasthenia gravis (MG) and Lambert-Eaton myasthenic syndrome (LEMS). RECENT FINDINGS: Recognition of new antigenic targets and improved diagnostic methods promise to improve the diagnosis of MG, although the clinical phenotypes associated with newer antibodies have not yet been defined. Future therapies might specifically target the aberrant immune response. The apparent increase in the prevalence of MG is not fully explained...

Out-of-field tumor response, which is also called abscopal effect, bystander effect, or non-target effect, can be regarded as localized irradiation induced systemic antitumorigenic effects, indicating shrinkage of a tumor distant from the irradiated site. Although abscopal effect has been documented in several tumor types, it is a very rare phenomenon which is clinically reported in non-small-cell-lung carcinoma (NSCLC). Herein, we represent a rare case of patient with NSCLC with two lesions in the upper lobe of left lung who, after receiving stereotactic ablative radiation therapy (SABR) to one of the tumors, had an apparent spontaneous regression of the other mass in the lung, suggestive of a radiation-induced abscopal effect...

Human-induced pluripotent stem cells (iPS) possess an intrinsic tumor tropism ability. However, iPS cells are impeded in clinical applications of tumor therapy due to the formation of teratomas and their survival in normal organs such as the liver, lungs, spleen and kidneys. Mitomycin C (MMC) can overcome this limitation by suppressing iPS proliferation. Herein, we fabricated a safe delivery system of iPS cells treated with MMC loading with gold nanorods (AuNRs) for the targeted photothermal treatment of gastric cancer...

Crude Amaryllidaceae alkaloids (AAs) extracted from Lycoris radiata are reported to exhibit significant anti-cancer activity. However, the specific alkaloids responsible for the pharmacodynamic activity and their targets still remain elusive. In this context, we strived to combine affinity ultrafiltration with topoisomerase I (Top I) as a target enzyme aiming to fish out specific bioactive AAs from Lycoris radiata. 11 AAs from Lycoris radiata were thus screened out, among which hippeastrine (peak 5) with the highest Enrichment factor (EF) against Top I exhibited good dose-dependent inhibition with IC50 at 7...

In recent years, the high heterogeneity of colorectal cancer (CRC) has become evident. Hence, biomarkers need to be developed that enable the stratification of patients with CRC into different prognostic subgroups and in relation to response to therapies, according to the distinctive tumour biology. Currently, only RAS-mutation status is used routinely as a negative predictive marker to avoid treatment with anti-EGFR agents in patients with metastatic CRC, and mismatch-repair status can guide the use of adjuvant chemotherapy in patients with early stage colon cancer...

Targeting self-renewal is an important goal in cancer therapy and recent studies have focused on Notch signalling in the maintenance of stemness of glioma stem cells (GSCs). Understanding cancer-specific Notch regulation would improve specificity of targeting this pathway. In this study, we find that Notch1 activation in GSCs specifically induces expression of the lncRNA, TUG1. TUG1 coordinately promotes self-renewal by sponging miR-145 in the cytoplasm and recruiting polycomb to repress differentiation genes by locus-specific methylation of histone H3K27 via YY1-binding activity in the nucleus...

BACKGROUND: The genome is under constant assault from a multitude of sources that can lead to the formation of DNA double-stand breaks (DSBs). DSBs are cytotoxic lesions, which if left unrepaired could lead to genomic instability, cancer and even cell death. However, erroneous repair of DSBs can lead to chromosomal rearrangements and loss of heterozygosity, which in turn can also cause cancer and cell death. Hence, although the repair of DSBs is crucial for the maintenance of genome integrity the process of repair need to be well regulated and closely monitored...

This study developed novel triblock pH-responsive polymeric micelles (PMs) using cholic acid-polyethyleneimine-poly-L-arginine (CA-PEI-pArg) copolymers. PEI provided pH sensitivity, while the hydrophilic cell-penetrating pArg peptide promoted cellular PM internalization. The copolymers self-assembled into PMs in aqueous solution at above the critical micelle concentration (2.98 × 10(-7) M) and encapsulated doxorubicin in the core region, with a 34.2% (w/w) entrapment efficiency. PMs showed pH-dependent swelling, increasing in size by almost sevenfold from pH 7...

RNA interference (RNAi) has been considered as a promising strategy for effective treatment of cancer. However, the easy degradation of small interfering RNA (siRNA) limits its extensive applications in gene therapy. For safe and effective delivery of siRNA, a novel vector system possessing excellent biocompatibility, highly efficient transfection efficiency and specific targeting properties has to be considered. In this study, we report the use of polyethyleneimine (PEI)-entrapped gold nanoparticles (Au PENPs) modified with an arginine-glycine-aspartic (Arg-Gly-Asp, RGD) peptide via a poly(ethylene glycol) (PEG) spacer as a vector for Bcl-2 (B-cell lymphoma-2) siRNA delivery to glioblastoma cells...

Hepatocellular carcinoma (HCC) is the most common primary liver cancer with high morbidity and mortality worldwide. Chemotherapy is recommended to patients with intermediate or advanced stage cancer. However, the conventional chemotherapy yields low desired response rates due to multidrug resistance, fast clearance rate, nonspecific delivery, severe side effects, low drug concentration in cancer cells, and so on. Nanoparticle-mediated targeted drug delivery system can surmount the aforementioned obstacles through enhanced permeability and retention effect and active targeting as a novel approach of therapeutics for HCC in recent years...

Lung cancer, ~80%-85% of which is non-small-cell lung cancer (NSCLC), is the leading cause of cancer-related mortality worldwide. Sensitizing mutations in epidermal growth factor receptor (EGFR) gene (EGFRm(+)), such as exon 19 deletions and exon 21 L858R point mutations, are the most important drivers in NSCLC patients. In this respect, small-molecule EGFR tyrosine kinase inhibitors (TKIs) have been designed and developed, which launched the era of targeted, personalized and precise medicine for lung cancer...
