A total of 366 tonsillar tissue samples were collected from healthy free-range pigs owned by farmers across 12 districts in Baise City, Guangxi, China. This initiative successfully isolated six strains of Carbapenem-Resistant (CRE), including four strains of , and one of and . Assessments utilizing Carbapenemase inhibitor enhancement test, in conjunction with the ResFinder resistance gene database, revealed that five strains carried the gene, while one strain possessed the gene.

Cancer-associated fibroblasts (CAFs) are key stromal cells in the tumor microenvironment (TME) that critically contribute to cancer initiation and progression. In bladder cancer (BCa), there is emerging evidence that BCa CAFs are actively involved in cancer cell proliferation, invasion, metastasis, and chemotherapy resistance. This review outlines the present knowledge of BCa CAFs, with a particular emphasis on their origin and function in BCa progression, and provides further insights into their clinical application.

Background: Endothelial-mesenchymal transition (EndoMT) is an emerging adaptive process that modulates lymphatic endothelial function to drive aberrant lymphatic vascularization in the tumour microenvironment (TME); however, the molecular determinants that govern the functional role of EndoMT remain unclear. Here, we show that cancer-associated fibroblast (CAF)-derived PAI-1 promoted the EndoMT of lymphatic endothelial cells (LECs) in cervical squamous cell carcinoma (CSCC).

Methods: Immunofluorescent staining of α-SMA, LYVE-1 and DAPI were examined in primary tumour samples obtained from 57 CSCC patients.

Cancer-associated fibroblasts (CAFs) are important, highly heterogeneous components of the tumor extracellular matrix that have different origins and express a diverse set of biomarkers. Different subtypes of CAFs participate in the immune regulation of the tumor microenvironment (TME). In addition to their role in supporting stromal cells, CAFs have multiple immunosuppressive functions, membrane and secretory patterns, against anti-tumor immunity.

The activation of stromal fibroblasts into cancer-associated fibroblasts (CAFs) has been suggested to promote primary tumor growth and progression; however, the mechanisms underlying the crosstalk between tumors and fibroblasts that drives stromal heterogeneity remain unknown. Here, we show that high Wnt2B levels were positively correlated with the number of CAFs in cervical cancer (CC). More importantly, Wnt2B was characteristically enriched in CC cell-secreted exosomes and transferred into fibroblasts to promote fibroblast activation via Wnt/β-catenin signaling, and inhibiting exosomal release or the Wnt/β-catenin signaling pathway diminished the activation induced by exosomal Wnt2B.

Lymphatic remodelling in the hypoxic tumour microenvironment (TME) is critically involved in the metastasis of cervical squamous cell carcinoma (CSCC); however, its underlying mechanisms remain unclear. Here, we uncovered a novel lymphatic pattern in the hypoxic TME, wherein lymphatic vessels (LVs) are encapsulated by tumour-associated macrophages (TAMs) to form an interconnected network. We describe these aggregates as LVEM (LVs encapsulated by TAMs) considering their advantageous metastatic capacity and active involvement in early lymph node metastasis (LNM).

Lymph node metastasis (LNM), a critical prognostic determinant in cancer patients, is critically influenced by the presence of numerous heterogeneous cancer-associated fibroblasts (CAFs) in the tumor microenvironment. However, the phenotypes and characteristics of the various pro-metastatic CAF subsets in cervical squamous cell carcinoma (CSCC) remain unknown. Here, we describe a CAF subpopulation with elevated periostin expression (periostin CAFs), located in the primary tumor sites and metastatic lymph nodes, that positively correlated with LNM and poor survival in CSCC patients.

The accumulation of tumour-associated macrophages (TAMs) in the hypoxic tumour microenvironment (TME) is associated with malignant progression in cancer. However, the mechanisms by which the hypoxic TME facilitates TAM infiltration are not fully understood. This study showed that high ZEB1 expression in hypoxic cervical cancer cell islets was positively correlated with CD163 TAM accumulation.

Article Synopsis
  • The study explores how exosomes from cervical cancer cells, specifically miR-221-3p, influence angiogenesis, which is vital for tumor growth in cervical squamous cell carcinoma (CSCC).
  • Researchers found a strong link between miR-221-3p expression and microvascular density in clinical CSCC samples, and confirmed its role in promoting angiogenesis through various in vitro and in vivo experiments.
  • The findings suggest that miR-221-3p downregulates a protein called Thrombospondin-2 (THBS2) in endothelial cells, indicating its potential as a new diagnostic biomarker and therapeutic target for advanced cervical cancer.

MicroRNAs have implicated in the relapse and metastasis of cervical cancer, which is the leading cause of cervical cancer-related mortality. However, the underlying molecular mechanisms need further elucidation. Our present study revealed that miR-221-3p is transcriptionally promoted in metastatic cervical cancer tissues compared with non-metastatic cervical cancer tissues.

Cervical cancer is the most frequent cause of gynecologic cancer-associated death worldwide. Animal models that demonstrate metastatic patterns consistent with the clinical course of cervical cancer are urgently needed to conduct studies focused on understanding the mechanisms of the disease and identifying optimal treatments. To address this, we established an orthotopic xenograft model of cervical cancer in female NOD-SCID mice using SiHa and ME180 cell lines stably expressing green fluorescent protein to evaluate the role of microRNA-21 (miR-21) in spontaneous lymph node metastasis in vivo.

Objective: To investigate the prevalence of physical state of HPV-16 DNA in cervical cancer and cervical precancerous carcinoma.

Methods: Multiplex PCR was adopted to detect the physical state of HPV in samples from 252 patients with cervical carcinoma, including 48 samples of cervical cancer, 204 cervical intraepithelial neoplasia (CIN ) (125 CIN I, 46 CIN II and 33 CIN III) and 20 normal samples from the subjects with hysteromyoma undergoing hysterectomy, respectively.

Results: Among 48 patients with cervical cancer, 31 (65.
