Mesenchymal tumors of the breast, which originate from the mammary stroma, are rare accounting for only approximately 0.5%-1% of all breast tumors. Pathologically, they can exist on a spectrum, ranging from benign to malignant. Such tumors may present with nonspecific findings on breast imaging, including mammography, ultrasound, and MRI, which can lead to diagnostic challenges. In the 2019 revised 5th edition of the World Health Organization classification, breast mesenchymal tumors are categorized into six groups. The current pictorial essay aimed to explore the clinical, pathological, and imaging characteristics of representative lesions in each category according to this six-group classification, with the ultimate goal of enhancing awareness for early diagnosis.

Thyroid cancer, a prevalent endocrine malignancy, is influenced by its tumor microenvironment (TME), with cancer-associated fibroblasts (CAFs) playing a pivotal role in disease progression. Molecularly, CAFs orchestrate a pro-tumorigenic niche via cytokine secretion and extracellular matrix (ECM) stiffening, underscoring their targetability. Therapeutic strategies, including small molecule inhibitor-based therapies, immune-based therapies, nanoparticle-based approaches, and combination regimens, have been evaluated for their efficacy in disrupting CAF functionality.

TP53 mutations are highly associated with hepatocellular carcinoma (HCC), a common and deadly cancer. However, few primary drivers in the progression of HCC with mutant TP53 have been identified. To uncover tumor suppressors in human HCC, a genome-wide CRISPR/Cas9-based screening of primary human hepatocytes with MYC and TP53 overexpression (MT-PHHs) is performed in xenografts.

Gastric cancer (GC) is the third leading cause of cancer mortality globally, often presenting with insidious symptoms that lead to late-stage diagnoses, underscoring the critical need for innovative diagnostic and therapeutic strategies. One such avenue is the exploration of ferroptosis, a regulated form of cell death implicated in various pathological conditions and malignancies. In this study, we demonstrate that brucine, an alkaloid derived from Strychnos nux-vomica, exerts significant antitumor effects on GC cells both in vitro and in vivo.

Bispecific T-cell engagers (BiTEs) are small-molecule antibodies that exhibits potent tumoricidal activity but suffer from a short plasma half-life. Mesenchymal stromal cells (MSCs) represent promising delivery vehicles for sustained therapeutic protein expression. In this study, we used human umbilical cord blood-MSCs (hUC-MSCs) as a delivery system to to secrete HER2/CD3 BiTE antibodies, thereby addressing the pharmacokinetic limitations of conventional BiTE therapies.

Long non-coding ribonucleic acids (lncRNAs) form a subclass of non-coding RNAs (ncRNAs), they are quite long and as their name non-coding suggests they do not have a role in protein coding. lncRNAs are vital in all the key steps of tumorigenesis, such as epithelial-mesenchymal transition, cancer stem cells formation, invasion, migration, and formation of the tumor vasculature. lncRNAs are classified into oncogenic or anti-tumor lncRNAs based on their functions.
