BACKGROUND: A key challenge in meeting the palliative care needs of people in advanced age is the multiple healthcare and social service agencies typically involved in their care. The 'patient navigator' model, originally developed in cancer care, is the professional solution most often recommended to address this challenge. However, little attention has been paid, or is known, about the role that family carers play in enabling their dying relatives to negotiate service gaps. AIM: To explore the role family caregivers play in helping people dying in advanced old age navigate health services at the end of life...

Ubiquitin specific protease 4 (USP4) is a member of the USPs family, which catalyzes the cleavage of ubiquitin from a series of protein substrates, thereby modulating a number of cellular signaling pathways. In this study, we aimed to explore the expression profile of USP4 in lung adenocarcinoma (LUAD) using large patient cohorts in the Cancer Genome Atlas and the International Cancer Genome Consortium and to investigate its prognostic value and the possible mechanisms of its dysregulation. Results showed that USP4 was significantly downregulated in LUAD tissues (N = 514) compared with the normal controls (N = 59)...

During tumor invasion, cancer cells change their morphology and mode of migration based on communication with the surrounding environment. Numerous studies have indicated that paracrine interactions from non-neoplastic cells impact the migratory and invasive properties of cancer cells. Thus, these interactions are potential targets for anticancer therapies. In this study, we showed that the flavones member baicalein suppresses the motility of breast cancer cells that is promoted by paracrine interactions. First, we identified laminin-332 (LN-332) as a principle paracrine factor in conditioned medium from mammary epithelium-derived MCF10A cells that regulates the morphology and motility of breast adenocarcinoma MDA-MB-231 cells...

One of the challenges of cancer is its heterogeneity and rapid capacity to adapt. Notwithstanding significant progress in the last decades in genomics and precision medicine, new molecular targets and therapies appear highly necessary. One way to approach this complex problem is to consider cancer in the context of its cellular and molecular microenvironment, which includes nerves. The peripheral nerves, the topic of this review, modulate the biological behavior of the cancer cells and influence tumor progression, including the events related to the metastatic spread of the disease...

While the use of next-generation androgen receptor pathway inhibition (ARPI) therapy has significantly increased the survival of patients with metastatic prostate adenocarcinoma (AdPC), several groups have reported a treatment-resistant mechanism, whereby cancer cells can become androgen receptor (AR) indifferent and gain a neuroendocrine (NE)-like phenotype. This subtype of castration-resistant prostate cancer has been termed "treatment-induced castration-resistant neuroendocrine prostate cancer" (CRPC-NE)...

NK cells are important in innate immunity for their capacity to kill infected or cancer cells. The killer cell immunoglobulin-like receptors (KIR) are a family of polymorphic genes with inhibitory and activating functions. The main driving force for gastric cancer (GC) development is a chronic response, which causes an increase of NK cells in the gastric mucosa. The aim of this work was to study polymorphisms in KIR genes in patients with either GC or non-atrophic gastritis (NAG). We studied 242 patients (130 with NAG and 112 with GC) and contrasted with 146 asymptomatic individuals...

Glutathione S transferase (GST) family is a key contributor in the detoxification mechanism of our body.Deletion of the genes within this family has been reported in the failure of detoxification system, to some extent leading to various types of cancers and other life threatening diseases. The existing data and reports on the association of null genotype of both GSTM1 and GSTT1 genes for various diseases are inconsistent. But knowledge of the polymorphic distributions of genotypes in different populations is important for investigating the risk factors in different epidemiological studies...

BACKGROUND: The ataxia telangiectasia mutated (ATM) gene is a moderate-risk breast cancer susceptibility gene; germline loss-of-function variants are found in up to 3% of hereditary breast and ovarian cancer (HBOC) families who undergo genetic testing. So far, no clear histopathological and molecular features of breast tumours occurring in ATM deleterious variant carriers have been described, but identification of an ATM-associated tumour signature may help in patient management. METHODS: To characterise hallmarks of ATM-associated tumours, we performed systematic pathology review of tumours from 21 participants from ataxia-telangiectasia families and 18 participants from HBOC families, as well as copy number profiling on a subset of 23 tumours...

Epidermal growth factor receptors (EGFRs) and their cytoplasmic tyrosine kinases play significant roles in cell proliferation and signaling. All the members of the EGFR/ErbB family are primary goals for cancer therapy, particularly for tumors of breast, cervix, ovaries, kidney, esophagus, prostate and non-small-cell lung carcinoma and head and neck tumors. However, the therapeutic ability of accessible anti-ErbB agents is limited. Therefore, recognizing EGF analogues or small organic molecules with high affinity for the extracellular domain of the EGFR is a critical target on cancer research...

Anoikis-resistance is an essential feature of cancer cells to obtain successful metastasis, whereas the molecular mechanism involved in this process of hepatocellular carcinoma (HCC) cells is not fully understood. Here we demonstrated that tripartite motif-containing (TRIM) 31, a new member of the TRIM family, was significantly upregulated in the anchorage-deprived HCC cells compared with their attached counterpart. When we blocked TRIM31 expression by its specific interference RNAs, the anoikis-resistance of HCC cells was significantly reversed...

Transmembrane-4-L-six-family member-1 (TM4SF1), a tumor-associated antigen, is overexpressed in most epithelial cell carcinomas and a potential target for antibody-mediated therapy. However, the role of TM4SF1 in gastric cancer has not been elucidated. The aim of this study was to investigate the clinical significance of TM4SF1 expression in gastric carcinoma (GC) tissues using 152 GC tissue samples and matched adjacent nontumor tissue samples analyzed by immunohistochemistry, and 13 fresh GC tissue samples analyzed by Western blotting...

Esophageal carcinoma is aggressive in nature and its prognosis is largely dependent on the degree of invasion. Histone deacetylase 6 (HDAC6), as the most unique member of HDACs family, has the positive activity to promote initiation and progression of various cancers via targeting multiple non-histone proteins in cytoplasm. In this study, we found that HDAC6 was over-expressed in three esophageal cancer cell lines (KYSE140, KYSE170, KYSE180) when compared to non-carcinoma esophageal epithelial cell HEEC-1. Then two HDAC6 specific siRNAs and HDAC6 inhibitor tubastatin A greatly suppressed KYSE140 and KYSE180 cells proliferation and migration, and the inhibition of cell motility was accompanied by elevated acetylation of α-tubulin, a target of HDAC6...

Glucose transporter 6 (GLUT6) is a member of the facilitative glucose transporter family. GLUT6 is up-regulated in several cancers, but is not widely expressed in normal tissues. Previous studies have shown that GLUT6 knockdown kills endometrial cancer cells that express elevated levels of the protein. However, whether GLUT6 represents a viable anti-cancer drug target is unclear because the role of GLUT6 in normal metabolic physiology is unknown. Herein we generated GLUT6 knockout mice to determine how loss of GLUT6 affected whole body glucose homeostasis and metabolic physiology...

The heat shock protein 90 (Hsp90) family plays a critical role in maintaining the homeostasis of the intracellular environment for human and prokaryotic cells. Hsp90 were identified as important target proteins for cancer and plant disease therapies. It was shown that gambogic acid (GBA) has the potential to inhibit human Hsp90. However, it is unknown, whether it is also able to act on the bacterial high temperature protein (HtpG) analogue. In this work, we screened GBA and nine other novel potential Hsp90 inhibitors using a miniaturized high throughput protein microarray-based assay and found that GBA shows an inhibitory effect on different Hsp90s after dissimilarity analysis of the protein sequence alignment...

Individuals with a history of colorectal or endometrial cancer younger than 50 years of age or with relatives younger than 50 years of age with a history of any of these malignances should be referred to clinical genetics for further diagnostic examinations and genetic counseling. Lynch syndrome is caused by mutations in mismatch repair genes and implicates an increased risk for colorectal cancer as well as endometrial cancer. Routine surveillance for this group of individuals regarding colorectal cancer by means of colonoscopy and endometrial cancer by means of transvaginal ultrasound as well as endometrial biopsies is recommended annually or biennially...
