IL-20RB mediates tumoral response to osteoclastic niches and promotes bone metastasis of lung cancer.

Bone is a common site of metastasis in lung cancer, but the regulatory mechanism remains incompletely understood. Osteoclasts are known to play crucial roles in osteolytic bone metastasis by digesting bone matrix and indirectly enhancing tumor colonization. In this study, we found that IL receptor 20 subunit β (IL-20RB) mediated a direct tumoral response to osteoclasts. Tumoral expression of IL-20RB was associated with bone metastasis of lung cancer, and functionally, IL-20RB promoted metastatic growth of lung cancer cells in bone. Mechanistically, tumor cells induced osteoclasts to secrete th

Predicting the Risk for Pathological Fracture in Bone Metastases.

Approximately 50-70% of patients with advanced cancer will experience bone metastases. The link between metastatic lesions and pathological bones is especially troubling since more metastases mean a higher chance of painful fractures, which can reduce mobility and often require surgery. Therefore, fracture risk predictions are essential for managing patients with bone metastases. However, the current methods for evaluating the risk of fractures are subjective, with low predictive value. This paper highlights how there being no effective comprehensive models for grouping patients by fracture ri

Hyperdiploid Multiple Myeloma with Novel Complex Structural Chromosome Abnormalities Associated with Poor Prognosis : A Rare Case Report.

Hyperdiploid multiple myeloma (MM) is associated with better prognosis and non-hyperdiploid subtype is associated with variable to adverse prognosis based on the nature of karyotype abnormality.  Rarely exceptions to this hyperdiploid and non-hyperdiploid divisions do exist in a minority. We report an adult male MM patient who showed hyperdiploid karyotype with few novel complex abnormalities and who showed poor clinical outcome. Conventional cytogenetic analysis carried out in 22 GTG banded metaphases showed 53,Y,der(X)t(X;22)(q27;q11.2),+3,+5,+6,+9,+11,+15,der(17)ins(17;1;3)(q11.2;?;?),der(1

Agricultural exposures and DNA damage in PBMC of female farmers measured using the alkaline comet assay.

Causal associations between site-specific cancer and diabetes risk: A two-sample Mendelian randomization study.

BackgroundBoth cancer and diabetes are complex chronic diseases that have high economic costs for society. The co-occurrence of these two diseases in people is already well known. The causal effects of diabetes on the development of several malignancies have been established, but the reverse causation of these two diseases (e.g., what type of cancer can cause T2D) has been less investigated.MethodsMultiple Mendelian randomization (MR) methods, such as the inverse-variance weighted (IVW) method, weighted median method, MR-Egger, and MR pleiotropy residual sum and outlier test, were performed to

Pathophysiology and Treatments of Complications of Waldenström's Macroglobulinemia.

Waldenstrom's macroglobulinemia (WM) or lymphoplasmacytic lymphoma is a B-cell malignancy characterized by lymphoplasmacytic cells in the bone marrow that secrete high amounts of immunoglobulin (Ig) M. The large pentameric structure of IgM leads to a variety of unique complications in WM, such as hyperviscosity syndrome, cryoglobulinemia and sensory neuropathy. Furthermore, malignant cells can infiltrate the central nervous system and lead to a variety of neurological complications, also known as Bing Neel Syndrome. Because of the unique pathophysiology of WM and these complications, their dia

Research on RNA modification in disease diagnosis and prognostic biomarkers: current status and challenges.

RNA modification, as a crucial post-transcriptional regulatory mechanism, plays a pivotal role in normal physiological processes and is closely associated with the onset and progression of various human diseases. Recent studies have highlighted significant alterations in the level of RNA modifications, including m6A, m6Am, m1A, m5C, m7G, ac4C, Ψ, and A-to-I editing, across multiple diseases. These findings suggest the potential of RNA modifications and their regulatory factors as biomarkers for early disease diagnosis and prognosis. This review provides an overview of statistical methods, mach

Identifying novel genes and biological processes relevant to the development of cancer therapy-induced mucositis: An informative gene network analysis.

Mucositis is a complex, dose-limiting toxicity of chemotherapy or radiotherapy that leads to painful mouth ulcers, difficulty eating or swallowing, gastrointestinal distress, and reduced quality of life for patients with cancer. Mucositis is most common for those undergoing high-dose chemotherapy and hematopoietic stem cell transplantation and for those being treated for malignancies of the head and neck. Treatment and management of mucositis remain challenging. It is expected that multiple genes are involved in the formation, severity, and persistence of mucositis. We used Ingenuity Pathway A

Establishment of a Temperature-Sensitive Model of Oncogene-Induced Senescence in Angiosarcoma Cells.

: Lesions with driver mutations, including atypical nevi and seborrheic keratoses, are very common in dermatology, and are prone to senescence. The molecular events that prevent senescent lesions from becoming malignant are not well understood. We have developed a model of vascular proliferation using a temperaturesensitive, large T antigen and oncogenic HRas. By elevating the temperature to 39 °C, we can turn off large T antigen and study the molecular events in cells with the Ras driver mutation. To assess the signaling events associated with the switch from a proliferative to a nonprolifera

Пространственное картирование оси AA-PGE2-EP при множественных повреждениях склероза.

Биоактивные липидные посредники (ДМ), получаемые из полиненасыщенных жирных кислот (ПУФА), являются ключевыми молекулами как инициирования, так и разрешения подстрекательских реакций. Предыдущие выводы свидетельствуют о том, что дисрегулируемый баланс LM, особенно в рамках арахидонической кислоты (АА), может способствовать реакции на нарушение разрешения и последующей хронической нейроинфламмации при множественном склерозе (МС). Однако на сегодняшний день местный биосинтез и сигнализация ММ в мозге людей с MS (PwMS) остаются неисследованными. Поэтому в этом исследовании мы впервые наметили рас

Recent Advances in Zinc Oxide Nanoparticles (ZnO NPs) for Cancer Diagnosis, Target Drug Delivery, and Treatment.

Cancer is regarded as one of the most deadly and mirthless diseases and it develops due to the uncontrolled proliferation of cells. To date, varieties of traditional medications and chemotherapies have been utilized to fight tumors. However, their immense drawbacks, such as reduced bioavailability, insufficient supply, and significant adverse effects, make their use limited. Nanotechnology has evolved rapidly in recent years and offers a wide spectrum of applications in the healthcare sectors. Nanoscale materials offer strong potential for curing cancer as they pose low risk and fewer complica

Penfluridol inhibits melanoma growth and metastasis through enhancing von Hippel‒Lindau tumor suppressor-mediated cancerous inhibitor of protein phosphatase 2A (CIP2A) degradation.

Melanoma's high metastatic potential, especially to the brain, poses significant challenges to patient survival. The blood‒brain barrier (BBB) is a major obstacle to the effective treatment of melanoma brain metastases. We screened antipsychotic drugs capable of crossing the BBB and identified penfluridol (PF) as the most active candidate. PF reduced melanoma cell viability and induced apoptosis. In animal models, PF effectively inhibited melanoma growth and metastasis to the lung and brain. Using immunoprecipitation combined with high-resolution mass spectrometry, and other techniques such as

NUPR1 Promotes Radioresistance in Colorectal Cancer Cells by Inhibiting Ferroptosis.

Radioresistance is a major clinical challenge and the underlying mechanism has not been thoroughly elucidated. In this study, a radioresistant (RR) cell line is established to explore the transcriptomic signatures of radioresistance in colorectal cancer (CRC). KEGG enriched pathway analysis demonstrated that ferroptosis is inactivated in RR cells. Further detection confirmed that radiotherapy can promote ferroptosis, and ferroptosis inactivation is one of the hallmarks of radioresistance in CRC. What's more, induction of ferroptosis can restore the radiosensitivity of CRC cells. Then, we perfo

Advanced non-small cell lung cancer treated with palliative systemic therapy complicated by calvarial metastasis: a case report.

BACKGROUND: Bony metastases are often seen in advanced cancers and lead to deterioration in patient quality of life with common complications of pain, bone fractures, and hypercalcemia. While most sites of metastasis to bone are observed in the axial skeleton from patients with a primary lung, breast or prostate cancer, metastases to the calvarium from lung cancer are less common, and thus less likely to be identified and managed. CASE DESCRIPTION: A 69-year-old Caucasian female with advanced non-small cell lung cancer (NSCLC) presented with worsening symptoms of widespread body pain, fatigue
