Figure S1. Bid-Deficient Mice Respond Normally to Full-Body -Irradiation Bid-/- mice and wt littermates of matching sex were subjected to a single dose of -radiation (2.5 Gy) and sacrificed for analysis 20 h later. (A) Bid-deficient mice had comparable total body and organ weights (spleen and thymus) as wt controls both before and after exposure to irradiation. (B) Total numbers of leukocytes and lymphocytes in

peripheral blood did not differ between bid-/- and wt mice. (C) Cell subset composition analysis in thymus, spleen and lymph nodes from untreated and irradiated wt and bid-/-

mice. No difference in percentages of lymphocyte subsets was observed between bid-/-

and wt mice. (D) Total cellularity and cell subset composition of thymus and spleen were found to be comparable between both untreated and irradiated bid-/- and wt mice. All graphs represent means +/-SD from 3-6 independent mice per genotype and treatment.

Figure S2. Blood Counts of Aged Bid-Deficient Mice on an Inbred C57BL/6 Genetic

Background

(A) White blood cell counts from 21 of our Bid-deficient mice (aged 14-21 months) and 8 of the original Bid-deficient (bidneo/neo) mice (aged 18-24 months) do not show abnormally elevated leukocyte numbers as compared to our 6-12 week old Bid-deficient mice or C57BL/6 wt mice. Each dot represents a single animal. (B) Peripheral blood analysis from the same aged Bid-deficient mice as in (A) shows normal lymphocyte, neutrophil and platelet counts, as well as normal levels of hemoglobin (HGB). Data represent means +/-SD from the indicated number (n) of animals.

FACS-sorted lymphocyte sub-populations (CD4+8+ immature thymocytes, CD4+8- and CD4-8+ mature T cells from lymph nodes, B220+sIgMhiDlo immature B cells and B220+sIgMloDhi mature B cells from lymph nodes and B220+sIg-c-Kit- pre-B cells from bone marrow) of bid-/- and control (wt) littermates were treated with the indicated doses of dexamethasone, recombinant FasL (FLAG-tagged and crosslinked with anti-FLAG antibodies), PMA or ionomycin. Percentages of viable cells were determined at the indicated time points by staining with PI plus AnnexinV-FITC followed by flow cytometric analysis. Data represent means +/-SD from cells of 3-6 independent mice of each genotype.

Figure S4. Bid-Deficient Primary MEF Undergo Normal Cell Cycle Arrest after Exposure to DNA Damage or Replicative Stress Independent lines of early passage (P1) wt and bid-/- (A) or wt and bidneo/neo (derived from the originally described Bid-deficient mice) (B) primary MEF were left untreated, -irradiated ( -rad., 5 and 20 Gy) or treated for 2 h with the indicated doses of etoposide (etop., 10 g/ml = 17 M), mitomycin C (mito C, 1 M), hydroxyurea (HU, 1 mM) or aphidicolin (aphid., 5 or 10 M) followed by 8 h incubation in drug free medium. Cell cycle distribution was then analyzed as described in Figure 5A. Data represent means +/-SD using 3 independent primary MEF (passage 1) derived from 3 independent embryos of each genotype.
