Hematological Malignancy-Derived Small Extracellular Vesicles and Tumor Microenvironment: The Art of Turning Foes into Friends.

Small extracellular vesicles (small EVs) are commonly released by all cells, and are found in all body fluids. They are implicated in cell to cell short- and long-distance communication through the transfer of genetic material and proteins, as well as interactions between target cell membrane receptors and ligands anchored on small EV membrane. Beyond their canonical functions in healthy tissues, small EVs are strategically used by tumors to communicate with the cellular microenvironment and to establish a proper niche which would ultimately allow cancer cell proliferation, escape from the imm

Landmark Cancer Clinical Trials and Real-World Patient Populations: Examining Race and Age Reporting.

BackgroundConcern exists that the clinical trial populations differ from respective cancer populations in terms of their age distribution affecting the generalizability of the results, especially in underrepresented minorities. We hypothesized that the clinical trials that do not report race are likely to suffer from a higher degree of age disparity.MethodsFood and Drug Administration (FDA) drug approvals from July 2007 to June 2019 were reviewed to identify oncology approvals, and trials with age details were selected. The outcomes studied were the weighted mean difference in age between the

Environmental Predictors of US County Mortality Patterns on a National Basis.

A growing body of evidence has found that mortality rates are positively correlated with social inequalities, air pollution, elevated ambient temperature, availability of medical care and other factors. This study develops a model to predict the mortality rates for different diseases by county across the US. The model is applied to predict changes in mortality caused by changing environmental factors. A total of 3,110 counties in the US, excluding Alaska and Hawaii, were studied. A subset of 519 counties from the 3,110 counties was chosen by using systematic random sampling and these samples w

Maximizing the impact of real-world evidence on cancer treatment: what do we need to achieve it?

There is an increasing number of studies using real-world data to examine outcomes of drugs in clinical practice. Therefore, it is crucial to carefully evaluate their quality and findings, extract valuable insights, acknowledge their limitations and identify gaps to advance further their use in decision-making. Here we provide an overview of the opportunities offered throughout drug lifecycle, and challenges presented by real-world evidence (RWE) studies. We also highlight the importance of the culture of transparency, along with the development of good practices for reporting RWE studies. In

Decoding iron deficiency in cancer: mechanisms, immune modulation, and therapeutic potential.

Iron is a vital micronutrient in many biological functions, including DNA metabolism, oxygen transport, and cellular energy generation. In this context, it is intimately linked to cancer biology. However, although many studies have comprehensively investigated and reviewed the effects of excess iron on tumor initiation and progression, the potential interrelations of iron deficiency with tumors have been largely neglected and need to be better defined. Recent studies have highlighted the complex relationship between iron deficiency and tumor biology. Iron deficiency in specific tumor types can

Exercise and the immune system: taking steps to improve responses to cancer immunotherapy.

The remarkable success of cancer immunotherapies has provided new hope to cancer patients. Unfortunately, a significant proportion of patients remain unable to respond to immunotherapy or maintain durable clinical responses. The lack of objective responses likely results from profound immune dysfunction often observed in patients with cancer. There is substantial evidence that exercise and physical activity can reduce incidence and improve outcomes in cancer patients. As the immune system is highly responsive to exercise, one potential avenue to improve immune function is through exercise and

Сенсорность клеток в глиальных клетках: последствия для множественного склероза.

Старение является наиболее распространенным фактором риска для развития заболевания множественным склерозом (MS). Клеточная сенсация, необратимое состояние остановки клеточного цикла, является основным фактором старения и, как было установлено, накапливается преждевременно в нейродегенеративных заболеваниях, включая болезнь Альцгеймера и Паркинсона. В последнее время внимание привлекает клеточная сенсация в центральной нервной системе пациентов MS, при этом ряд исследований свидетельствуют о том, что демиелинация вызывает клеточную сенесценцию с общими признаками p16INK4A и p21 выражения, окис

The role of CD8+ T cells in the immunoregulation of osteoporosis.

INTRODUCTION: Osteoporosis weakens the skeleton by lowering bone mass and damaging bone microarchitecture. A growing body of evidence points to disruptions in osteoimmune homeostasis as a key driver of this disease. In particular, apoptosis of bone cells and immune cells appears to be a critical contributing mechanism. Within the bone marrow, CD8+ T cells display a surprising functional duality: whether they protect bone or promote its loss depends heavily on local signals. Under healthy conditions or after mechanical loading, activated CD8+ T cells help maintain bone mass. They do so mainly b

Exercise-mobilized donor lymphocyte infusions enhanced with cytokine stimulation for the prevention and treatment of leukemic relapse after allogeneic hematopoietic cell transplantation.

Donor lymphocyte infusions (DLI) are a standard therapy following allogeneic hematopoietic cell transplantation (alloHCT) for preventing and treating leukemic relapse in high-risk patients, particularly those with myeloid malignancies such as acute myeloid leukemia (AML), chronic myeloid leukemia (CML), and myelodysplastic syndrome (MDS). However, the efficacy of DLI remains suboptimal and is accompanied by a significant risk of life-threatening graft-versus-host disease (GvHD), highlighting the urgent need for strategies that enhance graft-versus-leukemia (GvL) effects while mitigating GvHD.

Use of Real-World Evidence to Drive Drug Development Strategy and Inform Clinical Trial Design.

Interest in real-world data (RWD) and real-world evidence (RWE) to expedite and enrich the development of new biopharmaceutical products has proliferated in recent years, spurred by the 21st Century Cures Act in the United States and similar policy efforts in other countries, willingness by regulators to consider RWE in their decisions, demands from third-party payers, and growing concerns about the limitations of traditional clinical trials. Although much of the recent literature on RWE has focused on potential regulatory uses (e.g., product approvals in oncology or rare diseases based on sin

Acute myeloid leukemia with plasmacytoid dendritic cell proliferation: A case report and literature review.

The present study describes a rare case of plasmacytoid dendritic cell-associated acute myeloid leukemia (pDC-AML). A 70-year-old male patient was diagnosed with pDC-AML and underwent induction chemotherapy using the venetoclax + azacitidine (VA) regimen. After 3 weeks of treatment, bone marrow examination indicated a morphologic leukemia-free state (MLFS); however, the patient experienced persistent cytopenia, which was further complicated by severe pneumonia and gastrointestinal bleeding, both of which improved following treatment. After 3 weeks in MLFS, bone marrow morphology and minimal re

The roles of lncRNAs and miRNAs in pancreatic cancer: a focus on cancer development and progression and their roles as potential biomarkers.

Pancreatic ductal adenocarcinoma (PDAC) is among the most penetrative malignancies affecting humans, with mounting incidence prevalence worldwide. This cancer is usually not diagnosed in the early stages. There is also no effective therapy against PDAC, and most patients have chemo-resistance. The combination of these factors causes PDAC to have a poor prognosis, and often patients do not live longer than six months. Because of the failure of conventional therapies, the identification of key biomarkers is crucial in the early diagnosis, treatment, and prognosis of pancreatic cancer. 65% of the
