Here we show that lung tumor suppressor Gprc5a-knockout (KO) mice are susceptible to initiation of lung tumorigenesis. Bronchioalveolar stem cells (BASC) and alveolar type 2 (AT2) cells were aberrantly expanded in Gprc5a-KO mouse lungs compared with those in wild-type (WT) mice, suggesting that Gprc5a-KO might confer susceptibility to initiation by increasing the cell of origin in mouse lungs. BASCs from Gprc5a-KO mice (KO-BASC) exhibited significantly increased stemness and self-renewal potential and reduced differentiation capacity compared with BASCs from WT mice (WT-BASC). AT2 cells did not possess self-renewal potential regardless of Gprc5a status. KO-BASCs expressed a stem-like gene profile with upregulated Abcg2, EGFR, and NF-κB signaling compared with WT-BASCs.

Here, three metastasis-associated circRNAs identified in a previous circRNA-sequencing study were screened and validated in two HCC cohorts. CircRPN2 was downregulated in highly metastatic HCC cell lines and HCC tissues with metastasis. Pemrametostat supplier Patients with HCC with lower circRPN2 levels displayed shorter overall survival and higher rates of cumulative recurrence. Mechanistic studies in vitro and in vivo revealed that circRPN2 binds to enolase 1 (ENO1) and accelerates its degradation to promote glycolytic reprogramming through the AKT/mTOR pathway, thereby inhibiting HCC metastasis. CircRPN2 also acted as a competing endogenous RNA for miR-183-5p, which increases forkhead box protein O1 (FOXO1) expression to suppress glucose metabolism and tumor progression. In clinical samples, circRPN2 expression negatively correlated with ENO1 and positively correlated with FOXO1, and expression of circRPN2, either alone or in combination with ENO1 and FOXO1, was a novel indicator of HCC prognosis. These data support a model wherein circRPN2 inhibits HCC aerobic glycolysis and metastasis via acceleration of ENO1 degradation and regulation of the miR-183-5p/FOXO1 axis, suggesting that circRPN2 represents a possible therapeutic target in HCC.
The circRNA circRPN2 is a potential prognostic biomarker and therapeutic target in hepatocellular carcinoma that suppresses aerobic glycolysis and metastasis.

Inter- and intratumor heterogeneity in signaling within various tumor compartments and its impact on therapy are not well characterized due to the limited sensitivity of single-cell proteomic approaches. To overcome this barrier, we applied single-cell mass cytometry with a customized 26-antibody panel to PTEN-deleted orthotopic prostate cancer xenograft models to measure the evolution of kinase activities in different tumor compartments during metastasis or drug treatment. Compared with primary tumors and circulating tumor cells (CTC), bone metastases, but not lung and liver metastases, exhibited elevated PI3K/mTOR signaling and overexpressed receptor tyrosine kinases (RTK) including c-MET protein. Suppression of c-MET impaired tumor growth in the bone. Intratumoral heterogeneity within tumor compartments also arose from highly proliferative EpCAM-high epithelial cells with increased PI3K and mTOR kines in kinase activities across tumor compartments and cell states, which contribute to heterogeneous responses to targeted therapies.Over 50% of all patients with cancer are treated with radiotherapy. However, radiotherapy is often insufficient as a monotherapy and requires a nontoxic radiosensitizer. Squalene epoxidase (SQLE) controls cholesterol biosynthesis by converting squalene to 2,3-oxidosqualene. Given that SQLE is frequently overexpressed in human cancer, this study investigated the importance of SQLE in breast cancer and non-small cell lung cancer (NSCLC), two cancers often treated with radiotherapy. SQLE-positive IHC staining was observed in 68% of breast cancer and 56% of NSCLC specimens versus 15% and 25% in normal breast and lung tissue, respectively. Importantly, SQLE expression was an independent predictor of poor prognosis, and pharmacologic inhibition of SQLE enhanced breast and lung cancer cell radiosensitivity. In addition, SQLE inhibition enhanced sensitivity to PARP inhibition. Inhibition of SQLE interrupted homologous recombination by suppressing ataxia-telangiectasia mutated (ATM) activity via the translational upreotherapy efficacy.Tumor outcome is determined not only by cancer cell-intrinsic features but also by the interaction between cancer cells and their microenvironment. There is great interest in tumor-infiltrating immune cells, yet mast cells have been less studied. Recent work has highlighted the impact of mast cells on the features and aggressiveness of cancer cells, but the eventual effect of mast cell infiltration is still controversial. Here, we review multifaceted findings regarding the role of mast cells in cancer, with a particular focus on breast cancer, which is further complicated because of its classification into subtypes characterized by different biological features, outcome, and therapeutic strategies.
The Dietetic Assessment and Intervention in Lung Cancer (DAIL) study was an observational cohort study. It triaged the need for dietetic input in patients with lung cancer, using questionnaires with 137 responses. This substudy tested if machine learning could predict need to see a dietitian (NTSD) using 5 or 10 measures.

76 cases from DAIL were included (Royal Surrey NHS Foundation Trust; RSH 56, Frimley Park Hospital; FPH 20). Univariate analysis was used to find the strongest correlates with NTSD and 'critical need to see a dietitian' CNTSD. Those with a Spearman correlation above ±0.4 were selected to train a support vector machine (SVM) to predict NTSD and CNTSD. The 10 and 5 best correlates were evaluated.

18 and 13 measures had a correlation above ±0.4 for NTSD and CNTSD, respectively, producing SVMs with 3% and 7% misclassification error. 10 measures yielded errors of 7% (NTSD) and 9% (CNTSD). 5 measures yielded between 7% and 11% errors. SVM trained on the RSH data and tested on the FPH data resulted in errors of 20%.

Machine learning can predict NTSD producing misclassification errors <10%. With further work, this methodology allows integrated early referral to a dietitian independently of a healthcare professional.

Malignant bowel obstruction (MBO) is a common, challenging condition in advanced cancer. Oral water-soluble contrast medium (Gastrografin) has been used in the management of MBO without quality studies of its effectiveness and safety. The purpose of this study was to evaluate the feasibility, effectiveness and adverse effects of Gastrografin in patients with MBO and to assess feasibility of the study protocol.

A prospective, interventional, single-arm, open label study of Gastrografin across two centres. Patients with unresolved inoperable MBO after 24 hours of conservative medical management were given a single dose of 100 mL of oral Gastrografin.

Over 33 months, 69 individual patients were screened. Of the 20 recruited, 17 completed study assessments (85%). MBO resolved in 10 of 17 patients (59%). Gastrografin passed through to the rectum in 14 patients (78%). The most common adverse effects were diarrhoea, vomiting, nausea and abdominal pain.

Patient recruitment took longer than anticipated, but the study protocol is feasible. Gastrografin was found to be a relatively effective option for the treatment of MBO. An adeqautely powered randomised controlled trial is needed to formally assess the efficacy and safety of Gastrografin© in MBO.

Well-being care is widely offered and delivered in patients with cancer. However, very few studies have rigorously evaluated its benefits. The objective of this study was to evaluate the impact of four well-being treatments (foot reflexology, socio-aesthetics, sophrology and singing) provided in a healthcare facility.

Three hundred and seventy-four patients with cancer were offered a well-being treatment and agreed to evaluate the type of treatment received, the benefits felt as a result, and numerical evaluation scales for pain and well-being before and after the session.

The distribution of well-being treatments provided was as follows foot reflexology 19.0%, socio-aesthetics 63.9%, sophrology 6.7%, singing 10.4%. The average gain in pain relief was 1.01 on a scale of 0-10 (p<10
) and on well-being 6.97 on a scale of -10 to +10 (p<10
). One patient (0.3%) experienced pain induced by a foot reflexology session and one patient (0.3%) experienced a deterioration in well-being following a singing session.

The well-being treatments studied provided significant pain relief and increased well-being in patients with cancer after their completion.

Unsafe opioid prescribing can lead to significant patient harm and improving standards is a national priority. This report summarises a three-stage process relating to opioid prescribing, which has led to a sustained improvement.

Opioid prescriptions were reviewed retrospectively over a 4-year period in a tertiary cancer centre. The first audit cycle took place in 2017. When repeated in February 2020 following an opioid education programme implementation, prescribing remained poor. In September 2020, a quality improvement project (QIP) was developed with several interventions including opioid prescribing guidelines.

The first audit demonstrated that 76% met safe prescribing and 68% best practice. The second audit showed a deterioration in prescribing, 61% met safe prescribing and 39% best practice despite the implementation of an education programme. The QIP has led to an improvement in prescribing, at 4 months, 87% met safe prescribing and 56% best practice.

Despite implementation of a medical education initiative, a marked deterioration in safe opioid prescribing occurred.
