In recent years, the unprecedented increase in various cancers such as melanoma has caused researchers to focus more on the formulation of newer drugs with less side effects. In this study, we herein indicate the biogenic nanoarchitechtonics of Ag NPs template over chitosan/starch mixed hydrogel having notable reducing potential and anti-malignant melanoma effects. The two biopolymers also could stabilize as-synthesized Ag NPs. Physicochemical features of the material were further characterized over a range of advanced methods like X-ray diffraction (XRD), elemental mapping, dynamic light scattering (DLS), energy-dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), and Fourier transformed infrared spectroscopy (FT-IR). TEM analysis showed the spherical-shaped nanocomposite with the mean diameter in the range of 5-15 nm. Thereafter, the nanocomposite was exploited in the anti-malignant melanoma and cytotoxicity effects studies against various human malignant melanoma cell lines (HT144, RPMI7951, SKMEL2, UACC3074, WM266-4 and MUM2C) in situ. The bio-composite corresponding IC values were 193, 102, 227, 250, 301, and 203 μg/mL against MUM2C, WM266-4, UACC3074, SKMEL2, RPMI7951, and HT144 cell lines, respectively. A significantly high IC value offered an excellent antioxidant capacity of bio-composite. According to the above results, Ag NPs/CS-Starch nanomaterial can be utilized as an efficient drug to treat malignant melanoma in humans after doing clinical trial studies.

Background: The infiltration of tumor-infiltrating B cells and plasma cells in early-stage breast cancer has been associated with a reduced risk of distant metastasis. However, the influence of B-cell tumor infiltration on overall patient survival remains unclear.
Materials And Methods: This study explored the relationship between an antitumor immune response, measured by a 14-gene B-cell/immunoglobulin (IGG) signature, and mortality risk in 9638 breast cancer patients across three datasets.

Many patients with cancer approaching the end of life (EOL) continue to receive treatments that are unlikely to provide meaningful clinical benefit, potentially causing more harm than good. This is called overtreatment at the EOL. Overtreatment harms patients by causing side-effects, increasing health care costs, delaying important discussions about and preparation for EOL care, and occasionally accelerating death.

Therefore, the enrichment of tumor-antigen specific CAR-T cells in the desired region is critical for improving therapy efficacy and reducing systemic on-target/off-tumor side effects. Here, we functionalized human CAR-T cells with superparamagnetic iron oxide nanoparticles (SPIONs), making them magnetically controllable for site-directed targeting.

The continuous exploration and reporting of risk factors of melanoma is important for standardizing and reducing the incidence of the disease. Calcium signaling is a promising therapeutic target for melanoma; however, the relationship between total serum calcium levels and melanoma development remains unclear.
