Non-small cell lung cancer (NSCLC) is the predominant form of lung cancer and poses a significant public health challenge. Early detection is crucial for improving patient outcomes, with serum biomarkers such as carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCAg), and cytokeratin fragment 19 (CYFRA 21-1) playing a critical role in early screening and pathological classification of NSCLC. However, due to being mainly based on corresponding antibody binding reactions, existing detection technologies for these serum biomarkers have shortcomings such as complex operations, high false positive rates, and high costs.

Nanotheranostics in Breast Cancer Bone Metastasis: Advanced Research Progress and Future Perspectives.

Pharmaceutics

November 2024

Department of Breast Surgery, Cancer Hospital of China Medical University, Cancer Hospital of Dalian University of Technology, Liaoning Cancer Hospital and Institute, Shenyang 110042, China.

Breast cancer is the leading cause of cancer-related morbidity and mortality among women worldwide, with bone being the most common site of all metastatic breast cancer. Bone metastases are often associated with pain and skeletal-related events (SREs), indicating poor prognosis and poor quality of life. Most current therapies for breast cancer bone metastasis primarily serve palliative purposes, focusing on pain management, mitigating the risk of bone-related complications, and inhibiting tumor progression.

A comprehensive benchmark for multiple highly efficient base editors with broad targeting scope.

bioRxiv

December 2024

Key Laboratory of Bioresource Research and Development of Liaoning Province, College of Life and Health Sciences, Northeastern University, Shenyang, 110819, China.

As the toolbox of base editors (BEs) expands, selecting appropriate BE and guide RNA (gRNA) to achieve optimal editing efficiency and outcome for a given target becomes challenging. Here, we construct a set of 10 adenine and cytosine BEs with high activity and broad targeting scope, and comprehensively evaluate their editing profiles and properties head-to-head with 34,040 BE-gRNA-target combinations using genomically integrated long targets and tiling gRNA strategies. Interestingly, we observe widespread non-canonical protospacer adjacent motifs (PAMs) for these BEs.

Consensus on the lung cancer management after third-generation EGFR-TKI resistance.

Lancet Reg Health West Pac

December 2024

Guangdong Lung Cancer Institute, Guangdong Provincial People's Hospital (Guangdong Academy of Medical Sciences), Southern Medical University, Guangzhou, China.

Article Synopsis
  • Lung cancer is the most common type of cancer in the Asia-Pacific region, with non-small cell lung cancer (NSCLC) making up about 85% of cases, and a significant mutation rate of 40-60% in Asian patients with lung adenocarcinoma.
  • Third-generation EGFR tyrosine kinase inhibitors (EGFR-TKIs) have improved treatment for NSCLC with mutations, but managing resistance to these drugs is still a major issue with no standardized guidelines.
  • A set of recommendations has been developed, integrating international guidelines and regional clinical experiences, to help healthcare providers classify resistance, conduct clinical testing, and devise treatment strategies for patients struggling with resistance to third-generation EGFR-TKIs.

Article Synopsis
  • There is no standardized method for evaluating clinical complete response (cCR) in rectal cancer after neoadjuvant chemoradiotherapy (nCRT), leading to confusion with true pathological complete response (pCR).
  • MRI challenges, like tissue edema and fibrosis, along with accuracy issues in endoscopic biopsy, complicate the staging of local lesions post-nCRT.
  • Using transanal multipoint full-layer puncture biopsy (TMFP) could improve cCR assessment by integrating histological criteria, enhancing precision while reducing complications, although more research is necessary.

Breast cancer, a common malignancy and top cause of female cancer deaths globally, urgently requires new biomarkers and insights into its progression and chemoresistance. In this study, we identify ZNF593, a member of the zinc finger protein family, as an understudied oncogene in breast cancer. ZNF593 is significantly upregulated in breast cancer tissues compared to adjacent normal tissues, which is linked to poor prognosis and advanced clinicopathological features.

Background: Acute variceal bleeding (AVB), a life-threatening complication of liver cirrhosis, can be effectively treated by endoscopy, but there is a risk of early rebleeding after endoscopic variceal treatment (EVT). Thrombocytopenia is the most common hemostatic abnormality in liver cirrhosis. However, it is still unclear about whether thrombocytopenia increases the failure of EVT in cirrhotic patients with AVB.

Cisplatin is a platinum-based drug that is frequently used to treat multiple tumors. The anti-tumor effect of cisplatin is closely related to the tumor immune microenvironment (TIME), which includes several immune cell types, such as the tumor-associated macrophages (TAMs), cytotoxic T-lymphocytes (CTLs), dendritic cells (DCs), myeloid-derived suppressor cells (MDSCs), regulatory T cells (Tregs), and natural killer (NK) cells. The interaction between these immune cells can promote tumor survival and chemoresistance, and decrease the efficacy of cisplatin monotherapy.

Article Synopsis
  • Colorectal adenocarcinoma (COAD) is a significant cancer type, and this study investigates the role of wound healing-related genes in its progression to help improve diagnosis and treatment.
  • Seventy wound healing-associated genes were identified, leading to the discovery of four key genes (MMP2, FN1, NF1, PTK7) that show overexpression in COAD, which may serve as potential diagnostic markers.
  • These hub genes are linked to poor patient outcomes and tumor-promoting activities, with further implications for drug resistance and immune response in the context of COAD progression.

Roles of SIRT3 in cardiovascular and neurodegenerative diseases.

Ageing Res Rev

January 2025

Department of Cardiovascular Center, The First Hospital of Jilin University, Changchun, Jilin, China.

Sirtuin-3 (SIRT3) in mitochondria has nicotinamide adenine dinucleotide (NAD+)-dependent protein deacetylase activity. As such, SIRT3 is crucial in cardiovascular and neurodegenerative diseases. Advanced proteomics and transcriptomics studies have revealed that SIRT3 expression becomes altered when the heart or brain is affected by external stimuli or disease, such as diabetic cardiomyopathy, atherosclerosis, myocardial infarction, Alzheimer's disease, Huntington's disease, and Parkinson's disease.
