Purpose: Serine-threonine kinase11 (STK11) was originally identified in 1997 as the causative mutation that's responsible for Peutz-Jeghers Syndrome (PJS). Several recent studies have reported that the STK11 gene is an important human tumor suppressor gene in lung cancer. We evaluated the associations between the polymorphisms of the STK11 promoter region and the risk of lung cancer in 901 Koreans.
Materials And Methods: By direct sequencing, we first discovered three novel polymorphisms (-1,795 T>C, -981 C>T and -160 G>T) and four known polymorphisms (-1,580 C>T, -1,494 A>C, -881 A>G and -458 G>C) of the STK11 promoter region in 24 blood samples of 24 Korean lung cancer patients. Further genotype analyses were then performed on 443 lung cancer patients and 458 controls.
Results: We discovered three novel polymorphisms and we identified four known polymorphisms of the STK11 promoter region in a Korean population. Statistical analyses revealed that the genotypes and haplotypes in the STK11 gene were not significantly associated with the risk of lung cancer in a Korean population.
Conclusion: This is the first study that's focused on the association of STK11 promoter polymorphisms and the risk of lung cancer in a Korean population. To evaluate the role of the STK11 gene for the risk of lung cancer, the genotypes of the STK11 promoter region (-1,795 T>C, -1,494 A>C and -160 G>T) were determined in 901 Koreans, yet the result revealed no significant difference between the lung cancer patients and the controls. These results suggest that the three promoter polymorphisms we studied are not important risk factors for the susceptibility to lung cancer in Koreans.

Objective: The PACIFIC trial established standard therapy for patients with unresectable stage III NSCLC who did not progress after platinum-based concurrent chemoradiation therapy. However, real-world data, particularly from Latin America, remain limited. The LACOG 0120 study aimed to evaluate the efficacy and safety of consolidation therapy with durvalumab in a real-world setting in Brazil.

Studies show that propolis has antimicrobial, antifungal, antiviral, anti-inflammatory, antioxidant, antitumor, and immunomodulatory properties, and may protect against diseases such as diabetes, cardiovascular disease, and cancer. We aimed to extract compounds of brown propolis with hydroalcoholic solvents and evaluate their cytotoxic activity on tumor and non-tumor cells by MTT test. We tested the solute:solvent ratio (ethanol:water) and extraction time in a Shaker incubator (710 rpm) before conducting a central composite rotational design (CCRD) to optimize time and solvent mixture.

Induction of senescence by chemotherapeutic agents arrests cancer cells and activates immune surveillance responses to contribute to therapy outcomes. In this investigation, we searched for ways to enhance the NK-mediated elimination of senescent cells. We used a staggered screen approach, first identifying siRNAs potentiating the secretion of immunomodulatory cytokines to later test for their ability to enhance NK-mediated killing of senescent cells.

Copper is an essential nutrient for sustaining vital cellular processes spanning respiration, metabolism, and proliferation. However, loss of copper homeostasis, particularly misregulation of loosely bound copper ions which are defined as the labile copper pool, occurs in major diseases such as cancer, where tumor growth and metastasis have a heightened requirement for this metal. To help decipher the role of copper in the etiology of cancer, we report a histochemical activity-based sensing approach that enables systematic, high-throughput profiling of labile copper status across many cell lines in parallel.

Background: It has been proposed that more aggressive tumors trigger a stronger inflammatory response than less aggressive types. We hypothesize that systemic immune inflammatory index (SII) is associated with occult nodal disease (OND) in clinically node negative (cN0) patients undergoing lung resection for non-small cell lung cancer (NSCLC).
Study Design: The study included patients who underwent lung resection with nodal dissection, according to current guidelines, at a single center between 2010-2021 for NSCLC.
