Paraneoplastic symptoms, caused by a malignancy, but not directly related to invasion by the tumor or its metastases are the result of a wide variety of tumor-derived biologic mediators like hormones, peptides, antibodies, cytotoxic lymphocytes, autocrine and paracrine mediators. Recognition of paraneoplastic syndromes is important, as it may lead to an early diagnosis of cancer. There is some evidence that systemic inflammatory diseases, such as rheumatoid arthritis (RA), lupus, scleroderma or dermatomyositis may increase the risk for the development of malignancies, predominantly lymphoproliferative disorders. However, reports are somewhat controversial. Immunosuppressive and cytotoxic drugs used in antirheumatic therapy, such as methotrexate, cyclophosphamide, azathioprine or anti-TNF biologicals may also lead to the development of such tumors. Tumor-associated antigens may be produced by inflammatory cells and their production may be increased in RA and other autoimmune diseases.

Clonal hematopoiesis of indeterminate potential (CHIP) is associated with increased mortality and malignancy risk, yet the determinants of clonal expansion remain poorly understood. We performed sequencing at >4,000x depth of coverage for CHIP mutations in 6,986 postmenopausal women from the Women's Health Initiative at two timepoints approximately 15 years apart. Among 3,685 mutations detected at baseline (VAF ≥ 0.

Pancreatic cancer (PC) is a highly lethal malignancy with rapid progression and poor prognosis. Despite the widespread use of gemcitabine (Gem)-based chemotherapy as the first-line treatment for PC, its efficacy is often compromised by significant drug resistance. 1,2,3,4,6-Pentagaloyl glucose (PGG), a natural polyphenol, has demonstrated potential in sensitizing PC cells to Gem.

2-phenylchromen-4-one, commonly known as flavone, plays multifaceted roles in biological response that can be abundantly present in natural sources. The methoxy group in naturally occurring flavones promotes cytotoxic activity in various cancer cell lines by targeting protein markers, in facilitating ligand-protein binding mechanisms and activating cascading downstream signaling pathways leading to cell death. However, the lipophilic nature of these analogs is a key concern as it impacts drug membrane transfer.

Although curcumin is a well-known natural polyphenol with many biological activities, its clinical application has been limited by low aqueous solubility and stability. Therefore, curcumin derivatives have been proposed to overcome these limitations and increase anticancer activity. This study tested curcumin derivatives with modified feruloyl moieties ( and ) and the β-diketo moiety () to better understand their anticancer mechanism against human bladder cancer cells.

This study aimed to evaluate the diagnostic potential of soluble Programmed Death Ligand 1 (sPD-L1) and Programmed Death 1 (sPD-1) molecules in plasma, along with urinary mRNA biomarkers-Prostate-Specific Membrane Antigen (), Prostate Cancer Antigen 3 (), and androgen receptor () genes-for identifying clinically significant prostate cancer (PCa), defined as pathological stage 3. In a cohort of 68 PCa patients, sPD-L1 and sPD-1 levels were quantified using ELISA, while mRNA transcripts were measured by RT-qPCR. Results highlight the potential of integrating these liquid-based biomarkers.
