CDK4/6 inhibitors are routinely recommended agents for the treatment of advanced HRHER2 breast cancer. However, their therapeutic effectiveness in triple-negative breast cancer (TNBC) remains controversial. Here, we observed that the expression level of fibrous sheath interacting protein 1 (FSIP1) could predict the treatment response of TNBC to CDK4/6 inhibitors.

Ethyl 3-(N-butylacetamido) propanoate (EBAAP) is one of the most widely used mosquito repellents worldwide, and is also commonly used to produce cosmetics. Residues have recently been detected in surface and groundwater in many countries, and their potential to harm the environment is unknown. Therefore, more studies are needed to fully assess the toxicity of EBAAP.

HBX gene is essential for HBV replication, evading the surveillance of the immune system by integrating its sequence into the human genome. It also exists stably in human cells by inhibiting the expression and activity of mismatch repair-related pathway genes. Previous reviews have comprehensively summarized the role of HBx in liver-related diseases.

Increasing evidence illustrated that m6A regulator-mediated modification plays a crucial role in regulating tumor immune and angiogenesis microenvironment. And the combination of immune checkpoint inhibitor and anti-angiogenic therapy has been approved as new first-line therapy for advanced HCC. This study constructed a novel prognosis signature base on m6A-mediated modification and explored the related mechanism in predicting immune and anti-angiogenic responses.

Copper metabolism plays an important role in the tumor microenvironment, and cuproptosis is the last discovered programmed cell death process. However, the potential mechanism of cuproptosis in regulating the immune microenvironment of HCC remains unclear. A total of 716 HCC patients with complete mRNA expression and survival information were collected from three public HCC cohorts (TCGA-LIHC cohort, = 370; GSE76427 cohort, = 115; ICGC-LIRI cohort, = 231).

Background: Integrin family are known as key gears in focal adhesion for triple-negative breast cancer (TNBC) metastasis. However, the integrin independent factor TLN1 remains vague in TNBC.

Methods: Bioinformatics analysis was performed based on TCGA database and Shengjing Hospital cohort.

variants in D¯ Chinese pregnant women arose difficulties in management during pregnancy. Therefore, this study aims to precisely manage D¯ pregnant women by evaluating the spectrum of mutations in D¯ pregnant women and getting insight into the possible rare alleles of A total of 76 D¯ pregnant women were analyzed by performing polymerase chain reactions with sequence-specific primers (PCR-SSP), the 10 exons Sanger sequencing, zygosity detection, and mRNA sequencing (mRNA-seq). About 40% of alleles are variations of including 1227A homozygous, RHD-CE(2-9)-D, et al.

Long noncoding RNAs (lncRNAs) are emerging as critical regulators of gene expression and play fundamental roles in immune regulation. Growing evidence suggests that immune-related genes and lncRNAs can serve as markers to predict the prognosis of patients with cancers, including hepatocellular carcinoma (HCC). This study aimed to contract an immune-related lncRNA (IR-lncRNA) signature for prospective assessment to predict early recurrence of HCC.

Article Synopsis
  • Tumor metastasis is the leading cause of deaths from breast cancer, and this study focused on the role of CD44/CD24 breast cancer cells in delaying metastasis.
  • Analyzing 576 tissue specimens revealed that a higher frequency (≥19.5%) of CD44/CD24 cells correlates with delayed postoperative metastasis, particularly in triple-negative breast cancer (TNBC).
  • The research also found that CD44/CD24 TNBC cells can convert into cancer stem cells (CSCs), and silencing a specific gene can inhibit the conversion and metastasis processes, suggesting potential prognostic value for identifying patients at risk for delayed metastasis.

Endothelin receptor B (EDNRB) is one of the receptors in the endothelin axis and its upregulated expression is associated with tumorigenesis and metastasis of several types of solid tumors. However, the expression profile of EDNRB in breast cancer and its role in the progression of breast cancer are unclear. Here, we show that EDNRB expression is higher in metastatic tumors than in primary breast cancer, and is associated significantly with lymph node metastasis and poor survival in Chinese patients with breast cancer.

Staphylococcal nuclease domain-containing 1 (SND1) expression is crucial for breast cancer metastasis; however, the clinical implications of SND1 expression in breast cancer remain unclear. This study investigated the relationship of SND1 protein expression both with metastasis and the prognoses of 144 breast cancer patients over a 10-year follow-up. Chi-square tests revealed that the percentages of positive SND1 expression in breast cancer tumors were significantly associated with larger tumor size (>2 cm, P = 0.

Background: We aimed to develop a new nomogram to predict the probability of level 2 axillary lymph node metastasis (L-2-ALNM) in breast cancer (BC) patients treated with neoadjuvant chemotherapy (NAC).

Methods: Data were collected from 709 patients who received neoadjuvant chemotherapy and then underwent axillary lymph node (ALN) dissection between May 2009 and December 2015 at the Liaoning Cancer Hospital. The level 2 axillary lymph node metastasis (L-2-ALNM ) nomogram was created from the logistic regression model.

Background: The current management of the axilla in level 1 node-positive breast cancer patients is axillary lymph node dissection regardless of the status of the level 2 axillary lymph nodes. The goal of this study was to develop a nomogram predicting the probability of level 2 axillary lymph node metastasis (L-2-ALNM) in patients with level 1 axillary node-positive breast cancer.

Materials And Methods: We reviewed the records of 974 patients with pathology-confirmed level 1 node-positive breast cancer between 2010 and 2014 at the Liaoning Cancer Hospital and Institute.

Alzheimer's disease (AD) is a common form of dementia and amyloid-β peptide (Aβ) aggregation is considered to be one of its main causes. Paeoniflorin has been previously shown to attenuate cognitive damage inflicted by exogenous Aβ protein. Using transgenic Caenorhabditis elegans models expressing human Aβ, we demonstrate here that paeoniflorin can delay progressive paralysis caused by endogenous Aβ expression and reduce the amount of toxic Aβ oligomers in vivo, although it has no effect on Aβ aggregation in vitro.

Glutamate excitotoxicity is associated with many neurological diseases, including cerebral ischemia and neurodegenerative diseases. Tanshinone IIA, a diterpenoid naphthoquinone from , has been shown to suppress presynaptic glutamate release, but its protective mechanism against glutamate-induced neurotoxicity is lacking. Using SH-SY5Y human neuroblastoma cells, we show here that excessive glutamate exposure decreases cell viability and proliferation and increases LDH release.
