SLC39A14 promotes the development of esophageal squamous cell carcinoma through PI3K/Akt/mTOR signaling pathway.

Objectives: This study aims to investigate the expression of solute carrier family 39 member 14 (SLC39A14) in esophageal squamous cell carcinoma (ESCC) tissues and its prognosis, as well as the impact of SLC39A14 expression on the biological behavior of ESCC cells and associated mechanisms.

Methods: Bioinformatics analysis was utilized to compare the differential expression of SLC39A14 mRNA between esophageal cancer tissues and adjacent non-cancerous tissues. Immunohistochemistry was employed to evaluate SLC39A14 protein expression in human ESCC tissues and normal esophageal tissues, followed by an analysis of its association with clinicopathological parameters in esophageal cancer patients.

Primary cutaneous rhabdomyosarcoma with EWSR1/FUS::TFCP2 fusion: four new cases with distinctive morphology, immunophenotypic, and genetic profile.

EWSR1/FUS::TFCP2-rearranged rhabdomyosarcoma (RMS) is a rare tumor with an aggressive clinical course, a predilection for craniofacial bones, spindled and/or epithelioid histomorphology, and positive immunohistochemistry (IHC) for epithelial and myogenic markers, along with variable ALK expression. Herein, we present four additional cases of primary cutaneous TFCP2-rearranged RMS. Notably, one tumor (case 1) displayed a varied pathological spectrum, initially presenting as a low-grade spindle cell neoplasm, but progressed into a high-grade spindle/epithelioid tumor.

Advancements and challenges of R-loops in cancers: Biological insights and future directions.

R-loops involve in various biological processes under human normal physiological conditions. Disruption of R-loops can lead to disease onset and affect the progression of illnesses, particularly in cancers. Herein, we summarized and discussed the regulative networks, phenotypes and future directions of R-loops in cancers.

Role of repeat transurethral resection in no-muscle-invasive bladder tumour: an umbrella review.

Background: Repeat transurethral resection of bladder tumour (reTURB) is a conventional treatment for non-muscle-invasive bladder cancer (NMIBC) to enhance prognosis. However, the necessity of reTURB in NMIBC remains controversial owing to upstaging of treatments and new evidence.

Objectives: We performed an umbrella review to determine the need for reTURB in patients with NMIBC.

Construction of a hydrophilic porphyrin-based MOF@COF hybrid post-synthetic modification for -glycopeptides analysis in human serum.

A hybrid material, M@C-Br@GMA@Glu, consisting of a porphyrin-based metal-organic framework-covalent organic framework (MOF@COF), has been meticulously synthesized using a post-synthetic modification approach. This advanced material has demonstrated exceptional effectiveness in glycopeptide enrichment, characterized by an impressively low detection limit (0.2 fmol μL), high selectivity (1 : 2000), and loading capacity for glycopeptides (100 mg g).

Molecular classification of geriatric breast cancer displays distinct senescent subgroups of prognostic significance.

Breast cancer in the elderly presents distinct biological characteristics and clinical treatment responses compared with cancer in younger patients. Comprehensive Geriatric Assessment is recommended for evaluating treatment efficacy in elderly cancer patients based on physiological classification. However, research on molecular classification in older cancer patients remains insufficient.

Pan-cancer analysis of m1A writer gene RRP8: implications for immune infiltration and prognosis in human cancers.

Background: Ribosomal RNA Processing 8 (RRP8) is a gene associated with RNA modification and has been implicated in the development of several types of tumors in recent research. Nevertheless, the biological importance of RRP8 in pan-cancer has not yet been thoroughly and comprehensively investigated.

Methods: In this study, we conducted an analysis of various public databases to investigate the biological functions of RRP8.

The complex interplay of tumor-infiltrating cells in driving therapeutic resistance pathways.

Drug resistance remains a significant challenge in cancer treatment. Recently, the interactions among various cell types within the tumor microenvironment (TME) have deepened our understanding of the mechanisms behind treatment resistance. Therefore, this review aims to synthesize current research focusing on infiltrating cells and drug resistance suggesting that targeting the TME could be a viable strategy to combat this issue.

[Isolated intraductal carcinoma of the prostate: a clinicopathological and molecular analysis].

To study the clinicopathological features, immunohistochemical phenotypes, molecular changes, differential diagnosis and prognosis of isolated intraductal carcinoma of the prostate (iIDC-P). Three iIDC-P cases were collected retrospectively from 2016 to 2022 at Ningbo Clinical Pathology Diagnosis Center, Ningbo, China. The clinicopathologic features and immunophenotypic profiles were studied using light microscopy and immunohistochemistry.

[Several key and difficult issues related to the grading of urothelial carcinoma of urinary bladder].

Grading and staging are the most important prognostic factors for both non-invasive and invasive urothelial carcinomas, and are also one of the most common difficulties encountered by pathologists in the daily diagnostic practice of urothelial carcinoma. Recently, the International Society of Urological Pathology organized a survey and questionnaire conference on various issues related to the diagnosis, grading, and staging of urothelial carcinoma, and ultimately formed a series of consensus opinions. This article briefly summarizes the consensus opinions of this series, and combines them with the current pathological diagnosis status of urothelial carcinoma in China.

Reappraisal and refined diagnosis of ultrasonography and histological findings for hydatidiform moles: a multicentre retrospective study of 821 patients.

Aims: Specific identification of a hydatidiform mole (HM) and subclassification of a complete hydatidiform mole (CHM) or partial hydatidiform mole (PHM) are critical. This study aimed to reappraise the diagnostic performance of ultrasonography and histology with a refined diagnosis.

Methods: This was a retrospective, multicentre cohort study of 821 patients with histologically suspected HM specimens.

Myoepithelioma-Like Tumor of the Vulvar Region: A Clinicopathologic Study of Four Cases.

Myoepithelioma-like tumors of the vulvar region (MELTVR) are solid tumors found in the vulva of adult women. They have a similar histopathology to myoepithelioma but differ in immunohistochemical phenotype and genetic changes. In this study, we report four examples of MELTVR, occurred in the external genitalia and mons pubis of adult women aged 32 to 39 years.

Relationship between clonal evolution and drug resistance in bladder cancer: A genomic research review.

Bladder cancer stands as a prevalent global malignancy, exhibiting notable sex-based variations in both incidence and prognosis. Despite substantial strides in therapeutic approaches, the formidable challenge of drug resistance persists. The genomic landscape of bladder cancer, characterized by intricate clonal heterogeneity, emerges as a pivotal determinant in fostering this resistance.

PRRX1-fused mesenchymal neoplasm: A novel PRRX1::NCOA1 fusion transcript.

PRRX1-fused mesenchymal neoplasm is a recently identified, rare subcutaneous soft tissue neoplasm that is characterized by fusion of PRRX1 (exon 1) with NCOA1 (exon 13) in the majority of reported cases. Although initially considered to be fibroblastic, a possibility of neural or neuroectodermal differentiation has been suggested in a subset of cases. We report a 26-year-old female with a 4.
