While immune checkpoint inhibitors have been groundbreaking for cancer treatment, there are many reported cases of patients undergoing immunotherapy who have discontinued or temporarily interrupted treatment due to the development of autoimmune-related adverse effects. Here, we present a 63-year-old female with a history of psoriasis (in spontaneous remission) and newly diagnosed poorly differentiated lung adenocarcinoma (pTXN3M1a) who experienced a severe flare-up of her psoriasis three months after initiating single-agent pembrolizumab. The patient was initially treated with topical clobetasol propionate ointment, however, due to minimal response to this regimen, the patient was commenced on secukinumab; an IL-17 inhibitor. To our knowledge, this is the first case of the successful use of secukinumab for the treatment of immunotherapy-induced psoriasis. More importantly, immunotherapy with pembrolizumab was continued successfully with the co-administration of secukinumab without complications or the recurrence of non-small cell lung cancer (NSCLC).

Triple-negative breast cancer (TNBC) remains a significant global health challenge, emphasizing the need for precise identification of patients with specific therapeutic targets and those at high risk of metastasis. This study aimed to identify novel therapeutic targets for personalized treatment of TNBC patients by elucidating their roles in cell cycle regulation. Using weighted gene co-expression network analysis (WGCNA), we identified 83 hub genes by integrating gene expression profiles with clinical pathological grades.

A novel method for expressing and purifying large quantities of functional and stable human voltage-gated proton channel (hH1).

Purifying membrane proteins has been the limiting step for studying their structure and function. The challenges of the process include the low expression levels in heterologous systems and the requirement for their biochemical stabilization in solution. The human voltage-gated proton channel (hH1) is a good example of that: the published protocols to express and purify hH1 produce low protein quantities at high costs, which is an issue for systematically characterizing its structure and function.

Macrophages are pivotal in the body's defense and response to inflammation. They are present in significant numbers and are widely implicated in various diseases, including cancer. While molecular and histological techniques have advanced our understanding of macrophage biology, their precise function within the cancerous microenvironments remains underexplored.

Background: The treatment of glioblastomas (GBM) with radiation therapy is extremely challenging due to their invasive nature and high recurrence rate within normal brain tissue.
Purpose: In this work, we present a new metric called the tumour spread (TS) map, which utilizes diffusion tensor imaging (DTI) to predict the probable direction of tumour cells spread along fiber tracts. We hypothesized that the TS map could serve as a predictive tool for identifying patterns of likely recurrence in patients with GBM and, therefore, be used to modify the delivery of radiation treatment to pre-emptively target regions at high risk of tumour spread.
