Robbins 10th edition updates cover: cell field labelled ferroptosis and HPV E6 increasing TERT, Pathology MCQ.

Chapter-wise updates

New and expanded topics
ChapterUpdateKey fact
1. The cellSatellite DNALarge arrays of repeats (5 bp to 5 kb) at centromeres; besides spindle attachment, they maintain tightly packed heterochromatin
1. The cellGene editing with CRISPRโ€“Cas9Clustered regularly interspaced short palindromic repeats guide the Cas9 nuclease to cut a chosen DNA sequence, allowing precise genome editing
2. Cell injury and deathFerroptosisDescribed in 2012; iron-dependent lipid peroxidation that overwhelms glutathione-dependent (GPX4) antioxidant defences
3. Inflammation and repairNeutrophil extracellular trapsExpanded: chromatin webs that trap microbes; also a source of autoantigens and a driver of thrombosis
6. ImmunityTransplant rejectionMore detail on mechanisms of hyperacute, acute (cellular and antibody-mediated) and chronic rejection
7. NeoplasiaNew proto-oncogenesFLT3 (point mutations or internal tandem duplications in leukaemia); GNAQ (uveal melanoma); GNAS (pituitary adenoma)
7. NeoplasiaNew tumour suppressorsSDHB and SDHD (succinate dehydrogenase, TCA cycle) in familial paraganglioma and phaeochromocytoma
7. NeoplasiaHPV oncoproteinsE6 not only inactivates p53 but also increases telomerase (TERT) expression; E7 inactivates RB
8. Infectious diseasesSARS-CoV-2Added coverage of the virus and COVID-19

Exam focus

Ferroptosis is a favourite one-liner: iron-dependent cell death from lipid peroxidation, prevented by GPX4. Remember also that HPV E6 raises TERT as well as degrading p53.

Practice questions

PRACTICE ยท SBA1 of 3

Ferroptosis is triggered mainly by:

Show answer
Correct: B. RIPK3/MLKL drive necroptosis, gasdermin drives pyroptosis, and cytochrome c and caspases drive apoptosis.
PRACTICE ยท SBA2 of 3

Besides inactivating p53, the HPV E6 protein:

Show answer
Correct: B. E6 degrades p53 and upregulates TERT; E7 binds and inactivates RB.
PRACTICE ยท SBA3 of 3

GNAQ point mutations are characteristic of:

Show answer
Correct: B. GNAQ (and GNA11) mutations drive uveal melanoma; GNAS is linked to pituitary adenoma, FLT3 to AML and SDHx to paraganglioma.
