Abstract Melanoma is an aggressive skin cancer with historically poor survival due to low sensitivity to cytotoxic chemotherapy. Recently, novel therapeutic approaches, such as targeted therapy against the frequently activated mitogen-activated-protein-kinase (MAPK) pathway and immune- checkpoint inhibitor therapy have improved the prognosis of patients with metastasized melanoma. However, resistance formation or low response frequently occur. Thus, further mechanistic studies of melanoma progression and survival may eventually lead to therapeutic options.

  • Targeting the LKB1 Tumor Suppressor
    Send Orders for Reprints to [email protected] 32 Current Drug Targets, 2014, 15, 32-52 Targeting the LKB1 Tumor Suppressor Rui-Xun Zhao and Zhi-Xiang Xu* Division of Hematology and Oncology, Comprehensive Cancer Center, University of Alabama at Birmingham, Birmingham, AL, USA Abstract: LKB1 (also known as serine-threonine kinase 11, STK11) is a tumor suppressor, which is mutated or deleted in Peutz-Jeghers syndrome (PJS) and in a variety of cancers. Physiologically, LKB1 possesses multiple cellular functions in the regulation of cell bioenergetics metabolism, cell cycle arrest, embryo development, cell polarity, and apoptosis. New studies demonstrated that LKB1 may also play a role in the maintenance of function and dynamics of hematopoietic stem cells. Over the past years, personalized therapy targeting specific genetic aberrations has attracted intense interests. Within this review, several agents with potential activity against aberrant LKB1 signaling have been discussed. Potential strate- gies and challenges in targeting LKB1 inactivation are also considered. Keywords: LKB1 (serine-threonine kinase 11, STK11), AMP-activated protein kinase (AMPK), tumor suppression, mutations, targeting therapeutics. INTRODUCTION THE BIOLOGICAL FUNCTIONS OF LKB1 The LKB1 gene, also known as serine-threonine kinase Cell Metabolism 11 (STK11), was first identified by Jun-ichi Nezu of Chugai About a decade ago, studies from three different groups Pharmaceuticals in 1996 in a screen aimed at identifying new established that LKB1 is the long-sought kinase that phos- kinases [1]. The human LKB1 gene has been mapped to phorylates AMPK [9-11]. AMPK is a heterotrimeric enzyme chromosome 19p13.3. The gene spans 23 kb and is com- complex consisting of a catalytic subunit and regulatory posed of nine coding exons and a noncoding exon [2].

  • STK11 Gene Serine/Threonine Kinase 11
    STK11 gene serine/threonine kinase 11 Normal Function The STK11 gene (also called LKB1) provides instructions for making an enzyme called serine/threonine kinase 11. This enzyme is a tumor suppressor, which means that it helps keep cells from growing and dividing too fast or in an uncontrolled way. This enzyme helps certain types of cells correctly orient themselves within tissues ( polarization) and assists in determining the amount of energy a cell uses. This kinase also promotes a type of programmed cell death known as apoptosis. In addition to its role as a tumor suppressor, serine/threonine kinase 11 function appears to be required for normal development before birth. Health Conditions Related to Genetic Changes Breast cancer Inherited changes in the STK11 gene greatly increase the risk of developing breast cancer, as well as other types of cancer, as part of Peutz-Jeghers syndrome (described above). These mutations are thought to account for only a small fraction of all breast cancer cases. Peutz-Jeghers syndrome Inherited mutations in the STK11 gene cause Peutz-Jeghers syndrome, a condition characterized by the development of noncancerous growths called hamartomatous polyps in the gastrointestinal tract and a greatly increased risk of developing several types of cancer. More than 340 STK11 gene mutations have been identified in people with this condition. Many of these mutations result in the production of an abnormally short, nonfunctional version of the serine/threonine kinase 11 enzyme. Other mutations change single protein building blocks (amino acids) used to build the enzyme. Mutations in the STK11 gene impair the enzyme's tumor suppressor function, allowing cells to grow and divide without control or order.

  • KRAS Oncogene in Non-Small Cell Lung Cancer: Clinical Perspectives
    Román et al. Molecular Cancer (2018) 17:33 https://doi.org/10.1186/s12943-018-0789-x REVIEW Open Access KRAS oncogene in non-small cell lung cancer: clinical perspectives on the treatment of an old target Marta Román1,2, Iosune Baraibar1,2, Inés López2, Ernest Nadal3, Christian Rolfo4, Silvestre Vicent2,5,6 and Ignacio Gil-Bazo1,2,5,6* Abstract Lung neoplasms are the leading cause of death by cancer worldwide. Non-small cell lung cancer (NSCLC) constitutes more than 80% of all lung malignancies and the majority of patients present advanced disease at onset. However, in the last decade, multiple oncogenic driver alterations have been discovered and each of them represents a potential therapeutic target. Although KRAS mutations are the most frequently oncogene aberrations in lung adenocarcinoma patients, effective therapies targeting KRAS have yet to be developed. Moreover, the role of KRAS oncogene in NSCLC remains unclear and its predictive and prognostic impact remains controversial. The study of the underlying biology of KRAS in NSCLC patients could help to determine potential candidates to evaluate novel targeted agents and combinations that may allow a tailored treatment for these patients. The aim of this review is to update the current knowledge about KRAS-mutated lung adenocarcinoma, including a historical overview, the biology of the molecular pathways involved, the clinical relevance of KRAS mutations as a prognostic and predictive marker and the potential therapeutic approaches for a personalized treatment of KRAS-mutated NSCLC patients.

  • The Altered Activity of P53 Signaling Pathway by STK11 Gene Mutations
    Jiang et al. BMC Medical Genetics (2018) 19:141 https://doi.org/10.1186/s12881-018-0626-5 RESEARCHARTICLE Open Access The altered activity of P53 signaling pathway by STK11 gene mutations and its cancer phenotype in Peutz-Jeghers syndrome Yu-Liang Jiang1,2†, Zi-Ye Zhao3,4†, Bai-Rong Li2†, Fu Yang3, Jing Li2, Xiao-Wei Jin2, Hao Wang4, En-Da Yu4, Shu-Han Sun3* and Shou-Bin Ning2* Abstract Background: Peutz-Jeghers syndrome (PJS) is caused by mutations in serine/threonine kinase 11 (STK11) gene. The increased cancer risk has been connected to P53 pathway. Methods: PJS probands with STK11 mutation were included in the function analysis. P53 activity elevated by STK11 mutants was investigated using dual-luciferase reporter assay in vitro after constructing expression vectors of STK11 wild type and mutants generated by site-directed substitution. The association between the P53 activity and clinicopathological factors was analysis, especially the cancer history. Results: Thirteen probands with STK11 mutations were involved, and within the mutations, c.G924A was novel. P53 activity elevation caused by 6 truncating mutations were significantly lower than that of STK11 wild type (P < 0.05). Family history of cancer was observed in 5 families. Within them, P53 activity was reduced and cancer occurred before 40 in 2 families, while it was not significantly changed and cancers happened after 45 in the other 3 families. Conclusions: The affected P53 activity caused by STK11 mutations in PJS patients is significantly associated with protein truncation, while cancer risk in PJS can be elevated through pathways rather than P53 pathway.
