Special Issue Information

Dear Colleagues,

This Special Issue is the continuation of our Special Issue “Lung Cancer: From Molecular Mechanisms to Novel Therapeutics”.

Lung cancer remains the most significant cause of cancer-related deaths worldwide. Both molecular-targeted therapy and immunotherapy have revolutionized the diagnostic and therapeutic management of this heterogeneous disease, which includes different histologic and molecular subtypes. The number of actionable oncogenic drivers continues to expand in parallel with the development of novel targeted agents. On the other hand, several immune checkpoint inhibitors, as single agents or in combinatorial regimens, have been approved in metastatic non-small-cell lung cancer without targetable molecular alterations because of the demonstration of significant clinical efficacy and manageable toxicity profiles. Their development has been shifted in the early stages, with promising results. However, despite significant therapeutic advances, several challenges still remain, including the need for additional reliable biomarkers to select patients for immunotherapy and a better understanding of the complex biologic mechanisms leading to therapeutic resistance. This Special Issue will focus on (a) identification of new druggable driver gene alterations in lung cancer; (b) development of new drugs and combination therapies targeting specific molecular pathways; (c) current knowledge on primary and secondary mechanisms of resistance to targeted therapies or immunotherapy; and (d) current and emerging techniques to identify predictive biomarkers in tissue and liquid biopsy.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

From a previously performed proteomics screen, GPP130, or Golgi phosphoprotein of 130 kDa, was identified as a potential substrate of the proprotein convertase 7 (PC7; PCSK7). GPP130 is a type-II transmembrane protein with a luminal domain containing endosomal and Golgi-retrieval determinants, enabling a unique trafficking route. Most of the previous work on GPP130 relates to its binding and retrograde trafficking of the Shiga toxin. However, its cellular biology and its biochemical characterization remain understudied. Recently, GPP130 was reported to be implicated in cell cycle progression and cell proliferation in head and neck cancer cells. This led us to analyze the cBioPortal for Cancer Genomics, revealing that the GPP130/GOLIM4 gene is amplified in many cancers, including lung, ovarian, and cervical. This observation led us to use the A549 lung cancer cell line to investigate the growth-regulating roles of endogenous and overexpressed GPP130 and to analyze the impact of its cleavage/shedding by PC7 and/or Furin on cellular growth. Our cell-based assays suggest that GPP130 is a novel pro-protein convertase substrate that increases cell proliferation in A549, SKOV3, and HeLa cells, and that the latter activity is enhanced following its cleavage by PC7 and/or Furin into a membrane-bound N-terminal product and secreted C-terminal fragments. This novel work sheds light on the cell biology of the poorly characterized GPP130, its proliferative activity, and modulation upon its shedding by PC7 and Furin in lung cancer progression.
