Article Synopsis
  • The study examined how lifestyle factors, particularly smoking and alcohol consumption, affect the progression of colorectal cancer (CRC) in patients with hereditary CRC syndromes, focusing on Asian individuals.
  • Data from 202 patients were analyzed, revealing that smoking and a high number of polyps significantly increased the risk of developing advanced polyp burden in polyposis CRC syndromes, while smoking and heavy drinking were linked to earlier CRC diagnoses in Lynch syndrome patients.
  • The findings suggest that lifestyle changes, like quitting smoking and reducing alcohol intake, could potentially lower the risk of hereditary CRC in genetic mutation carriers.

Article Synopsis
  • - Non-small cell lung cancer (NSCLC) is categorized into two main types: lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LSCC), but some tumors display mixed characteristics that may be influenced more by other factors than histology alone.
  • - A study using data from 691 patients identified five molecular subtypes of NSCLC, including one associated with the PI3K-Akt pathway that correlates with high rates of metastasis and poor survival, regardless of the specific type of NSCLC.
  • - The research highlights the immune microenvironment's role, revealing different immune cell compositions and neoantigen levels across subtypes, which can help predict patient outcomes; immunological subtypes showed better responses to

Fasiglifam, a candidate targeting GPR40, showed efficacy in clinical trials for type 2 diabetes but exerted liver toxicity. This study investigated the drug-induced liver injury (DILI) risk of Xelaglifam, a new GPR40 agonist, based on the potential toxicity mechanism of Fasiglifam; transporter inhibition, mitochondrial dysfunction, reactive metabolite formation, and covalent binding to proteins. In the hepatobiliary transporter assay, Xelaglifam showed a broader safety margin (>10-fold) against bile acid transporters, suggesting its less likelihood to cause bile acids accumulation, unlike Fasiglifam (<10-fold safety margin).

Article Synopsis
  • SAVI is a rare autoinflammatory disease that can present similarly to systemic lupus erythematosus (SLE), as seen in a Korean patient with early-onset interstitial lung disease and symptoms like recurrent fever and skin ulcers.
  • The patient was misdiagnosed with SLE due to positive antibody tests but was later confirmed to have SAVI through genetic testing at age 29.
  • Despite multiple treatments, including immunosuppressive therapy and tofacitinib, her lung condition deteriorated, emphasizing the need for timely diagnosis and intervention for better outcomes in cases of SAVI.

Xelaglifam, developed as a GPR40/FFAR1 agonist, induces glucose-dependent insulin secretion and reduces circulating glucose levels for Type 2 diabetes treatment. This study investigated the effects of Xelaglifam in comparison with Fasiglifam on the in vitro/in vivo anti-diabetic efficacy and selectivity, and the mechanistic basis. In vitro studies on downstream targets of Xelaglifam were performed in GPR40-expressing cells.

Triple-negative breast cancer (TNBC) accounts for approximately 15-20% of all breast cancer types, indicating a poor survival prognosis with a more aggressive biology of metastasis to the lung and a short response duration to available therapies. Ibulocydine (IB) is a novel (cyclin-dependent kinase) CDK7/9 inhibitor prodrug displaying potent anti-cancer effects against various cancer cell types. We performed in vitro and in vivo experiments to determine whether IB inhibits metastasis and eventually overcomes the poor drug response in TNBC.

Background: Several PD-1 antibodies approved as anti-cancer therapies work by blocking the interaction of PD-1 with its ligand PD-L1, thus restoring anti-cancer T cell activities. These PD-1 antibodies lack inter-species cross-reactivity, necessitating surrogate antibodies for preclinical studies, which may limit the predictability and translatability of the studies.

Results: To overcome this limitation, we have developed an inter-species cross-reactive PD-1 antibody, GNUV201, by utilizing an enhanced diversity mouse platform (SHINE MOUSE™).

Article Synopsis
  • Despite 20 years of awareness, cascade genetic testing for hereditary breast and ovarian cancer (HBOC) is underused among at-risk relatives due to various psychosocial factors.
  • A review of studies from 2012-2022 identified 3 main categories and 12 subcategories of facilitators and barriers to testing: facilitators (like family support), bidirectional factors (like perceptions and emotions), and barriers (like negative family reactions).
  • Healthcare providers should evaluate these factors to enhance family communication about genetic testing and promote informed decision-making.

Dendritic cells (DCs) are readily generated from the culture of mouse bone marrow (BM) treated with either granulocyte macrophage-colony stimulating factor (GM-CSF) or FMS-like tyrosine kinase 3 ligand (FLT3L). CD11cMHCII or CD11cMHCII cells are routinely isolated from those BM cultures and generally used as -generated DCs for a variety of experiments and therapies. Here, we examined CD11c cells in the BM culture with GM-CSF or FLT3L by staining with a monoclonal antibody 2A1 that is known to recognize mature or activated DCs.
