The RECQL helicase prevents replication fork collapse during replication stressThis work shows that RECQL is an essential player in the protection of stalled replication forks and possibly the restart of broken replication forks, thereby representing a target for cancer therapy.
DDX5 promotes oncogene C3 and FABP1 expressions and drives intestinal inflammation and tumorigenesisIn intestinal epithelial cells (IECs), DDX5 promotes the expression of immune response genes and oncogenes posttranscriptionally and is a novel therapeutic target for treating colitis and intestinal cancers.
Thymosin α1 protects from CTLA-4 intestinal immunopathologyThis study demonstrates that Tα1 protects mice from anti–CTLA-4–induced colitis and sustains its antitumor activity, thus suggesting that Tα1 may be used in combination protocols.
Small molecule inhibitors and a kinase-dead expressing mouse model demonstrate that the kinase activity of Chk1 is essential for mouse embryos and cancer cellsThe study use small molecule inhibitors and a kinase-dead expressing mouse model to demonstrate that the kinase activity of Chk1 is essential for mouse embryos and cancer cells.
STAG1 vulnerabilities for exploiting cohesin synthetic lethality in STAG2-deficient cancersThis work highlights the degradation of STAG1 and inhibition of its interaction with cohesin as promising therapeutic strategies for exploiting synthetic lethality to treat STAG2-mutated tumors and lays the groundwork for the discovery of STAG1-directed small molecules.
Tradeoff between metabolic i-proteasome addiction and immune evasion in triple-negative breast cancerEngaging the immunoproteasome helps maintain proteostasis during TNBC development, but ultimately leads to increased immune visibility and favorable prognosis. Assessing i-proteasome expression could augment the prognostic and/or predictive value of TILs assessment in diagnostic practice.
Integrin α3β1 in hair bulge stem cells modulates CCN2 expression and promotes skin tumorigenesisAlthough hair bulge stem cells are not the cancer cells-of-origin, they contribute to two-stage DMBA/TPA skin carcinogenesis in an α3β1-dependent manner.
MAPK pathway mutations in head and neck cancer affect immune microenvironments and ErbB3 signalingMAPK mutations favor HNSCC survival, revealing the broad clinical utility of MAPK pathway mutations in prognosis and potentially in precision immunotherapy.
Pancreatic cancer triggers diabetes through TGF-β–mediated selective depletion of islet β-cellsPancreatic ductal adenocarcinoma formation culminates in hyperactivation of transforming growth factor β signaling, which in turn induces selective depletion of β-cell mass and thereby leading to new-onset diabetes.
Immunoglobulin expression in the endoplasmic reticulum shapes the metabolic fitness of B lymphocytesImmunoglobulins shape mitochondrial function by driving ER expansion, this form of metabolic control is independent of the role the immunoglobulins play as part of the antigen receptor on the cell surface.
