This report describes the management of small cell lung cancer (SCLC) transformation in a patient with untreated ALK-mutated advanced disease and a minimal smoking history, and a separate case of a de novo SCLC in a lifelong nonsmoker found to have a potentially targetable ERBB2 alteration. In the first case, chemotherapy followed by a targeted inhibitor was chosen due to the presence of the ALK rearrangement, as well as a somewhat discordant response to induction chemotherapy, suggesting possible progression of the ALK inhibitor-sensitive component. Molecular testing for the identification of driver mutations should be considered in patients with SCLC who have light/never smoking histories in order to help understand the incidence and ultimate optimal management strategies.

Adaptive immune resistance in cancer describes the various mechanisms by which tumors adapt to evade anti-tumor immune responses. IFN-γ induction of programmed death-ligand 1 (PD-L1) was the first defined and validated adaptive immune resistance mechanism. The endoplasmic reticulum (ER) is central to adaptive immune resistance as immune modulatory secreted and integral membrane proteins are dependent on ER.

One hallmark of cancer is the upregulation and dependency on glucose metabolism to fuel macromolecule biosynthesis and rapid proliferation. Despite significant pre-clinical effort to exploit this pathway, additional mechanistic insights are necessary to prioritize the diversity of metabolic adaptations upon acute loss of glucose metabolism. Here, we investigated a potent small molecule inhibitor to Class I glucose transporters, KL-11743, using glycolytic leukemia cell lines and patient-based model systems.

Aedes mosquitoes transmit pathogenic arthropod-borne (arbo) viruses, putting nearly half the world's population at risk. Blocking virus replication in mosquitoes is a promising approach to prevent arbovirus transmission, the development of which requires in-depth knowledge of virus-host interactions and mosquito immunity. By integrating multi-omics data, we find that heat shock factor 1 (Hsf1) regulates eight small heat shock protein (sHsp) genes within one topologically associated domain in the genome of the Aedes aegypti mosquito.
