“…The data presented here can accomplish the hypothetical picture of events occurring in the tumor according to which monocytes/macrophages and other stromal cells, primarily fibroblasts and neutrophils, undergo rewiring depending on their amount and powerfulness of cancer cells; the balance between these abilities may be established by proteostasis mechanisms, including molecular chaperones governed by HSF1 and autophagy. This process may involve cancer cells even in the very beginning of tumor growth and dissemination, e.g., tumor-initiating cells, stem-like cells and drug-tolerant persisters [ 46 , 47 ].…”

“…A previous study suggests that GPX1 may induce cisplatin-based chemoresistance in NSCLC [32], but the exact role of this gene in lung cancer is still unclear [33]. Investigation of pathway-level differences of tumors compared to NATs mirrored known cancer hallmarks, including the impairment of glycolysis [34], unfolded protein response [35], translation [36], ECM organization [37] pathways or signaling by RTKs [38]. Importantly, except for the first two processes, these hallmarks were only detected at the protein level, highlighting the relevance of proteomics in spatial profiling studies.…”

“…In many cases, tiny populations of tumor cells constituting so called minimal residual disease, acquire a dormant phenotype that is characterized by extremely low growth and metabolic activity and an increased level of autophagy [ 1 ]. Such cells, known as disseminated tumor cells or drug-tolerant persisters, demonstrate the attributes of cancer stem cells (CSCs) [ 2 , 3 ]. Irrespective of their origin, dormant cells persist in special niches as single cells or sparse colonies (micrometastases) for an indefinite period of time.…”
