Medical News Today: Killing cancer softly: New approach halts tumor growth

Cancer therapy can sometimes, paradoxically, help the cancer to spread. New research shows why that is, and what can be done to stop it.

SummaryNon-small cell lung cancer (NSCLC) treatment was booming at this year ’s ASCO 2018 meeting as several well-performed phase III trials with practice-changing potential were presented. Thereby immune checkpoint blockade (ICB) consolidated its major role in the treatment of NSCLC patients without genetic alterations and extended its use by showing impressive data on I CB combination therapies (mainly combined with chemotherapy). Furthermore the role of predictive biomarkers for ICB therapy (Programmed death-ligand 1 [PD-L1] expression, tumor mutational burden [TMB] testing and others) have been further ...

AbstractPurpose of reviewThere is growing evidence to suggest that gut microbiota plays an important role in colorectal carcinogenesis. Western diet is associated with gut microbial dysbiosis, which leads to inflammation, oxidative stress, and genotoxic effects, all common risk factors for colorectal cancer.Recent findingsFusobacterium nucleatum,Helicobacter pylori,Bacteroides fragilis,Escherichia coli,and Streptococcus bovis are the main bacterial species associated with colorectal carcinogenesis. Gut microbiota transforms both diet- (meat, processed meat products, fat) and host (bile acids)-derived precursors into carcin...

Publication date: Available online 20 October 2018Source: Journal of Molecular Graphics and ModellingAuthor(s): Süleyman Selim Çınaroğlu, Emel TimuçinAbstractReplication Protein A (RPA) mediates DNA Damage Response (DDR) pathways through protein-protein interactions (PPIs). Targeting the PPIs formed between RPA and other DNA Damage Response (DDR) mediators has become an intriguing area of research for cancer drug discovery. A number of studies applied different methods ranging from high throughput screening approaches to fragment-based drug design tools to discover RPA inhibitors. Although these method...

In this study, we successfully incorporated a hydrophobic drug, bortezomib (Bor), into folic acid (FA)-conjugated Cs/Chs self-assembled NPs (Bor/Cs/Chs-FA) for colorectal cancer therapy. The particle size and polydispersity index of Bor/Cs/Chs-FA were ∼196.5 ± 1.2 nm and ∼0.21 ± 0.5, respectively. A pH-dependent release profile was observed, facilitating cancer cell-targeted drug release under an acidic tumor microenvironment. Moreover, in vitro data revealed enhanced cellular uptake and apoptosis in folate receptor-expressing colorectal cancer cells (HCT-116 and HT-29) as compared to that in lung can...

The structure of HLPR was a tightly condensed siRNA-peptide inner core in turn surrounded by the disordered lipid layer and thin HA coating from which the EGFR-targeted amino acid sequences of IVNQPTYGYWHY partially protrude outside of cell surfaces. Both HA and IVNQP...

In this report, we propose that the molecular mechanisms of beneficial actions of CR should be classified and discussed according to whether they operate under rich or insufficient energy resource conditions. Future studies of the molecular mechanisms of the beneficial actions of CR should also consider the extent to which the signals/factors involved contribute to the anti-oxidative, anti-inflammatory, anti-tumor and other CR actions in each tissue or organ, and thereby lead to anti-aging and prolongevity.

Abstract OBJECTIVES: To examine symptom occurrence and severity and overall health-related quality of life (HRQOL) in patients receiving cancer therapy guided by genomic profiling (matched therapy) and patients receiving nonmatched therapy. SAMPLE & SETTING: A retrospective and secondary analysis of data from 129 individuals with breast or gynecologic cancer receiving care at a regional outpatient cancer center. METHODS & VARIABLES: Descriptive statistics and multiple linear regression analyses were performed. Study variables included symptom occurrence and severity, HRQOL, and person- and health...

Publication date: Available online 19 October 2018Source: Pharmacology &TherapeuticsAuthor(s): Ryuji Yamaguchi, Lydia Lartigue, Guy PerkinsAbstractRegulation of both the extrinsic and the mitochondria-dependent intrinsic apoptotic pathways plays a key role in the development of the hematopoietic system, for sustaining cell survival during generation of various cell types, in eliminating cells with dual identities such as CD4/CD8 double-positive cells1,2, for sustaining cells during the rapid clonal expansion phase3, as well as eliminating cells during the contraction phase4. The anti-apoptotic protein Mcl-1 is necessar...
