Osteosarcoma (OS) is a prevalent primary malignant bone tumor, typically managed through a combination of neoadjuvant chemotherapy and surgical interventions. Recent advancements in early detection and the use of novel chemotherapeutic agents have significantly improved the 5-year survival rate of OS patients. However, some patients fail to achieve the desired treatment outcomes despite undergoing intensive chemotherapy and surgicals procedures, with chemotherapy resistance emerging as a critical factor contributing to therapeutic failure in OS.

Articular cartilage damage is predominantly caused by trauma, osteoarthritis (OA), and other pathological conditions. The limited intrinsic capacity of cartilage tissue to self-repair necessitates timely intervention following acute injuries to prevent accelerated degeneration, leading to the development of planar arthritis or even osteoarthritis. Unfortunately, current therapies for articular cartilage damage are inadequate in effectively replacing or regenerating compromised cartilage due to the absence of suitable tissue-engineered artificial matrices.

PD-L1 is constitutively expressed on various immune cells, epithelial cells, and cancer cells, where it functions as a co-stimulatory molecule capable of impairing T-cell mediated immune responses. Upon binding to PD-1 on activated T-cells, the PD-1/PD-L1 interaction triggers signaling pathways that can induce T-cell apoptosis or anergy, thereby facilitating the immune escape of tumors.

Strong immunosuppression mediated by CCR8 Tregs observed in breast and lung malignancies suggest for their functional significance in cancer therapy. To date, detailed characterization of tumor-infiltrating CCR8 Tregs cells in colorectal cancer (CRC) is limited.

This study utilised Ganoderma lucidum mycelium to prepare a mycelium-based leather substitute with zinc cross-linking (MF-Zn) and evaluated its physicochemical properties and sensory performance; the conventional Cr tanning method was used as reference. Results demonstrated that Zn and Cr formed cross-links with the -OH and -NHOCH groups in the polysaccharides of chitin, while Zn selectively bonded to a fraction of -NH groups in cystine and phenylalanine.

Despite standard hormonal therapy that targets the androgen receptor (AR) attenuates prostate cancer (PCa) effectively in the initial stage, the tumor ultimately converts to castration-resistant prostate cancer (CRPC), and the acquired resistance is still a great challenge for the management of advanced prostate cancer patients. The tumor microenvironment (TME) consists of multiple cellular and noncellular agents is well known as a vital role during the development and progression of CRPC by establishing communication between TME and tumor cells. Additionally, as primary prostate cancer progresses towards metastasis, and CRPC always experiences bone metastasis, the TME is conducive to the spread of tumors to the distant sits, particularly in bone.
