Lung cancer is one of the most lethal forms of cancer known to man, affecting millions of individuals worldwide. Despite advancements being made in lung cancer treatments, the prognosis of patients with the disease remains poor, particularly among patients with late‑stage lung cancer. The elucidation of the signaling pathways involved in lung cancer is a critical approach for the treatment of the disease. Over the past decades, accumulating evidence has revealed that Rho‑associated kinase (ROCK) is overexpressed in lung cancer and is associated with tumor growth. The present review discusses recent findings of ROCK signaling in the pathogenesis of lung cancer that were conducted in pre‑clinical studies. The significant role of ROCK in cancer cell apoptosis, proliferation, migration, invasion and angiogenesis is discussed. The present review also suggests the use of ROCK as a potential target for the development of lung cancer therapies, as ROCK inhibition can reduce multiple hallmarks of cancer, particularly by decreasing cancer cell migration, which is an initial step of metastasis.

The purpose of this study was to investigate ROCK2 activation in squamous cell carcinogenesis and assess its co-operation with rasHa and fos oncogene activation together with loss of PTEN mediated AKT regulation. The analysis of ROCK deregulation with these genes in the MAP Kinase and PI3K pathways, two of the most commonly deregulated signalling systems, employed a well-characterised, transgenic mouse skin model of multi-stage carcinogenesis. A major goal was to study co-operation between these genes in the conversion of benign tumours to malignancy and investigate subsequent progression to aggressive carcinomas, given these are the most significant clinical stages of carcinogenesis from a patient’s viewpoint; and also investigated effects of ROCK2 deregulation on the processes of normal epidermal differentiation. ROCK2 is an effector protein of RhoA, which is a member of the ras superfamily and ROCK2 activation has been associated with tumour progression via an increase in tissue stiffness mediated by changes in actomyosin cytoskeleton leading to increased cellular motility. Thus, ROCK2 expression is commonly associated with the later events in cancer. Furthermore, there are many studies investigating ROCK2 in cancer given that it may be a useful therapeutic target in being downstream of oncogenic ras signalling. Yet, relatively few studies have explored the possibilities of a definite link that confirms the co-operation status of ROCK2 activation with ras/MAPK/fos and /or PTEN/PI3K/AKT pathways in SCC aetiology. Thus, questions exist as to exactly when does ROCK2 activation become causal; and what are the collaborating genes involved in the mechanism that drive the early or late stage events in carcinogenesis. To begin to answer these questions, inducible ROCK2 activation has been introduced into a well-characterised transgenic mouse skin carcinogenesis model that expressed a combination of ras and fos activation, driven by a modified human keratin 1 vector (HK1)
