Incorporation of dermoscopy and artificial intelligence (AI) is improving healthcare professionals' ability to diagnose melanoma earlier, but these algorithms often suffer from a "black box" issue, where decision-making processes are not transparent, limiting their utility for training healthcare providers. To address this, an automated approach for generating melanoma imaging biomarker cues (IBCs), which mimics the screening cues used by expert dermoscopists, was developed. This study created a one-minute learning environment where dermatologists adopted a sensory cue integration algorithm to combine a single IBC with a risk score built on many IBCs, then immediately tested their performance in differentiating melanoma from benign nevi. Ten participants evaluated 78 dermoscopic images, comprised of 39 melanomas and 39 nevi, first without IBCs and then with IBCs. Participants classified each image as melanoma or nevus in both experimental conditions, enabling direct comparative analysis through paired data. With IBCs, average sensitivity improved significantly from 73.69% to 81.57% ( = 0.0051), and the average specificity improved from 60.50% to 67.25% ( = 0.059) for the diagnosis of melanoma. The index of discriminability (') increased significantly by 0.47 ( = 0.002). Therefore, the incorporation of IBCs can significantly improve physicians' sensitivity in melanoma diagnosis. While more research is needed to validate this approach across other healthcare providers, its use may positively impact melanoma screening practices.

Individuals with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) have a high risk of developing other malignancies (OMs). The development of OMs may be associated with the advanced age of CLL/SLL patients, presence of a tumor-promoting microenvironment, immune alterations inherent to CLL/SLL, or chemotherapy. Importantly, the occurrence of OMs following frontline fludarabine, cyclophosphamide and rituximab (FCR) treatment is associated with a reduction in the overall survival (OS).

Yet the differential roles and biological functions of co-targeting transcription factors is poorly understood. In melanoma, three highly-related transcription factors are co-expressed: The mTORC1-regulated TFEB and TFE3, that are key effectors of a wide range of metabolic and microenvironmental cues; and MITF, that controls melanoma phenotypic identity.

Background: Cucurbitacin E glucoside (CEG), a prominent constituent of Cucurbitaceae plants, exhibits notable effects on cancer cell behavior, including inhibition of invasion and migration, achieved through mechanisms such as apoptosis induction, autophagy, cell cycle arrest, and disruption of the actin cytoskeleton.
Objective: Melanoma, the fastest-growing malignancy among young individuals in the United States and the predominant cancer among young adults aged 25 to 29, poses a significant health threat. This study aims to elucidate the apoptotic mechanism of CEG against the melanoma cancer cell line (A375).

Extracellular vesicles (EVs)-mediated communication by cancer cells contributes towards the pro-tumoral reprogramming of the tumor microenvironment. Viral infection has been observed to alter the biogenesis and cargo of EVs secreted from host cells in the context of infectious biology. However, the impact of oncolytic viruses on the cargo and function of EVs released by cancer cells remains unknown.

Introduction: Anorectal melanoma (ARM) is rare and highly lethal neoplasm. It has a poorer prognosis compared with cutaneous ones. Sentinel lymph node biopsy (SLNB) has become the preferred method of nodal staging method for cutaneous melanoma.
