Somatic mitochondrial DNA (mtDNA) mutations are prevalent in tumors, yet defining their biological significance remains challenging due to the intricate interplay between selective pressure, heteroplasmy, and cell state. Utilizing bulk whole-genome sequencing data from matched tumor and normal samples from two cohorts of pediatric cancer patients, we uncover differences in the accumulation of synonymous and nonsynonymous mtDNA mutations in pediatric leukemias, indicating distinct selective pressures. By integrating single-cell sequencing (SCS) with mathematical modeling and network-based systems biology approaches, we identify a correlation between the extent of cell-state changes associated with tumor-enriched mtDNA mutations and the selective pressures shaping their distribution among individual leukemic cells.

Marine oil and gas resources are abundant in deepwater regions, where the shallow seabed harbors natural gas hydrate layers due to the cold temperature and high-pressure environment. Hydrates are prone to thermal decomposition, which can compromise the integrity of cement sealing and even lead to accidents like blowouts. While current low-hydrated heat cement systems mitigate hydrate decomposition from cement hydration heat during the waiting period for cementing, they do not address heat transfer from deep strata to shallow hydrate layers through fluid circulation in the tubing during deep oil and gas development.

Background: Accurate mandibular reconstruction following tumor ablation is important yet challenging. While computer-assisted surgery and surgical navigation have been applied widely in maxillofacial reconstruction, the accuracy and the efficacy remain debatable due to the native mobile nature. This study aimed to evaluate the surgical outcomes and accuracy of mandibular reconstruction aided by different types of adjunctive computer-assisted techniques with or without intraoperative navigation.

Article Synopsis
  • Ovarian cancer, the deadliest gynecological cancer, faces major treatment obstacles, particularly with PARP inhibitors (PARPi) for BRCA1/2-mutated tumors, as resistance to these drugs is a significant challenge.
  • An experiment developed a PARPi-resistant cell line (A2780-OlaR), revealing increased levels of CYP1B1, and demonstrated that manipulating its expression affected responses to Olaparib, the PARP inhibitor.
  • The study concludes that CYP1B1 plays a crucial role in PARPi resistance, showing how chromatin accessibility impacts drug effectiveness and suggesting new strategies to fight ovarian cancer.

  • Immunogenic cell death (ICD) is effective in enhancing cancer immunotherapy by activating the immune response against tumors.
  • The study identifies a new synthetic compound, G4P-C7A, which induces ICD and promotes the release of immune-activating signals and maturation of dendritic cells.
  • G4P-C7A shows potential in treating tumors by generating reactive oxygen species, inhibiting tumor growth when injected alone, and enhancing effects when combined with existing immunotherapies.

To identify patterns of medication adherence during the pandemic and factors associated with these patterns among Medicaid-enrolled individuals with schizophrenia who had highly adherent medication use prior to the COVID-19 pandemic. We used Medicaid claims from Philadelphia to identify individuals with schizophrenia ≥ 18 years of age, their demographic characteristics, and health service use. We used group trajectory models to identify adherence trends, and ANOVA to examine associations between adherence groups and demographic characteristics and service use.

  • FGFR1 is being studied as a significant target for lung cancer treatment, with various inhibitors showing promise in preclinical trials.
  • Researchers developed a peptide hydrogel that combines an FGFR1 inhibitor, nintedanib, for localized delivery and controlled release, aiming to minimize side effects.
  • Experiments indicate that this hydrogel not only reduces the survival and movement of lung cancer cells but also enhances the effectiveness of the treatment in mouse models compared to using the inhibitor alone.

Lung cancer is one of the most common malignant tumours worldwide and its high mortality rate makes it a leading cause of cancer-related deaths. To address this daunting challenge, we need a comprehensive understanding of the pathogenesis and progression of lung cancer in order to adopt more effective therapeutic strategies. In this regard, integrating multi-omics data of the lung provides a highly promising avenue.

Article Synopsis
  • - Outcomes for patients with locally advanced head and neck cancer (HNC) are poor, with a 50% five-year survival rate, so a test to detect molecular residual disease (MRD) in blood is essential to identify recurrence risk within the first two years after treatment.
  • - A study involving 325 patients assessed MRD using blood samples collected over time, finding that those with MRD positivity had significantly worse recurrence-free survival rates, particularly in HPV-negative cases.
  • - The developed tissue-agnostic test demonstrated high sensitivity (91%) and specificity (88%) for predicting recurrences as much as 14.9 months before they occurred, validating its effectiveness for monitoring HNC patients post-treatment.

Microglia are critical innate immune cells of the brain. targeting of microglia using gene-delivery systems is crucial for studying brain physiology and developing gene therapies for neurodegenerative diseases and other brain disorders such as NeuroAIDS. Historically, microglia have been extremely resistant to transduction by viral vectors, including adeno-associated virus (AAV) vectors.

  • - The National Healthy Food and Drink Policy, introduced in New Zealand's public hospitals in 2016, aimed to provide healthier food options for staff and visitors, with a study assessing its implementation from 1 to 5 years after its initiation.
  • - Audits conducted in 2017 and 2021 showed significant changes in the classification of food items, with an increase in green (healthy) options and a decrease in red (unhealthy) items across serviced outlets and vending machines.
  • - By 2021, green items represented 20.7% of available choices, a notable increase from 14.0% in 2017, though none of the health boards fully met the policy's ideal standards for healthy

Pulmonary macrophages from COPD patients are characterized by lower phagocytic and bactericidal activity whereas there is hypersecretion of pro-inflammatory cytokines. The prominent decline of GATA2 expression in pulmonary macrophages from COPD patients inspired us to figure out its role during COPD development. The expression levels of GATA2 were decreased in alveolar macrophages isolated from cigarette smoke (CS)-induced COPD mice and cigarette smoke extract (CSE)-treated macrophages.
