We describe the synthesis, MMP-2 and 9 potency, and in vitro evaluation of a series of α-sulfone hydroxmate MMP inhibitors conjugated to a series of dyes with different absorption/emission lamina maxima's that can be used to visualize tumors.

Triple-negative breast cancer (TNBC) is an aggressive subtype often characterized by high lymphocyte infiltration, including tumor-infiltrating B cells (TIBs). These cells are present even in early stages of TNBC and associated with microinvasion. This study shows that co-culturing TNBC cells with B cells increases Interleukin-1β (IL-1β) expression and secretion.

Priego and colleagues identify a secreted glycoprotein TIMP1, expressed downstream of the transcription factor STAT3, in a subpopulation of STAT3+ reactive astrocytes as a mediator of immunosuppression in late-stage brain metastases. The STAT3 inhibitor silibinin enhances the preclinical efficacy of the combined PD-1/CTLA4 immune checkpoint blockade, providing a rationale to translate the combination therapy into clinical use for this underserved patient group with poor prognosis.

Immune-based combinations are the cornerstone of the first-line treatment of metastatic renal cell carcinoma patients, leading to outstanding outcomes. Nevertheless, primary resistance and disease progression is a critical clinical challenge. To properly address this issue, it is pivotal to understand the mechanisms of resistance to immunotherapy and tyrosine kinase inhibitors, that tumor eventually develop under treatment.

Matrix metalloproteinases (MMPs) are M2 macrophage markers that are modulated by inflammation. A disintegrin and metalloproteinases (ADAMS) and those with thrombospondin motifs (ADAMTS) regulate the shedding of membrane-bound proteins, growth factors, cytokines, ligands, and receptors; MMPs, ADAMS, and ADAMTS may be regulated by tissue inhibitors of metalloproteinases (TIMPs). This study aimed to determine whether these interacting proteins were dysregulated in PCOS.

Matrix metalloproteinase (MMP)-induced collagen degradation at the resin-dentin interface remains a significant challenge for maintaining the longevity of dental restorations. This study investigated the effects of epigallocatechin-3-gallate (EGCG), a potent MMP inhibitor, on dental adhesive curing efficiency when encapsulated in halloysite nanotubes (HNTs). EGCG-loaded HNTs were incorporated into a commercial dental adhesive (Adper Scotchbond Multi-Purpose) at 7.
